Discussion Question What benefits do Citrix solutions bring to your organization? How do these solutions affect your role?

Desktop Virtualization Architecture Citrix built XenDesktop 7.x on an architecture that offers simple, powerful configuration and operations management and cloud-style automation and scalability. XenDesktop delivers Windows applications and desktops as secure mobile services. End users can use tablets, smart phones, PCs, Macs, and thin clients to self-select applications from an application store. High Definition Experience (HDX) technologies, a key component of XenDesktop, optimize the end-user experience for different endpoints and network conditions. Virtualized environments are very complex and have many components that are necessary for them to function as intended. In this section, you will review some of the main components as well as how they communicate. This high-level understanding of components allows you to more efficiently troubleshoot end-user issues.

Understanding Citrix XenDesktop 7.x Components The diagram below details the components found in a XenDesktop environment.

Citrix Receiver Installed on end-user devices, Citrix Receiver provides end users with secure access to documents, applications, and desktops from any of the end-users’ devices. Receiver provides: • • • •

Simple, self-service access to virtual desktops, applications, and IT services. A hi-definition experience on any network or device. Instant updates to end users with IT control and visibility. Easier management of enterprise data, applications, and desktops through secure, centralized deployment to any device.

Citrix StoreFront The app store concept came about from the increase in mobile activity by end users, providing them with a centralized access point for all the applications specific to a platform. StoreFront enables you to create universal enterprise application stores to facilitate your end users' mobile workstyles while giving you centralized control. StoreFront is an integral component of any XenDesktop implementation, authenticating end users to Microsoft Active Directory and managing the delivery of desktops and applications from your servers in the datacenter to end-users' devices. End users access StoreFront stores through Citrix Receiver or by browsing to a Receiver for Web or Desktop Appliance site, which enable end users to access stores through a webpage. StoreFront keeps a record of each end-user application and automatically updates devices, ensuring that end users have a consistent experience as they roam between their devices.

Delivery Controller Installed on servers in the datacenter, the Delivery Controller consists of services that communicate with the hypervisor or physical machines to distribute applications and desktops, authenticate and manage end-user access, and broker connections between end users and their virtual desktops and applications. The Controller manages the state of the desktops, starting and stopping them based on demand and administrative configuration. Each site can have one or more Delivery Controllers.

Citrix Studio Citrix Studio is the management console that enables you to manage and troubleshoot your XenDesktop environment, eliminating the need for separate management consoles for managing delivery of applications and desktops. Studio is also used by Citrix administrators to deploy and assign applications and desktops to end users.

Citrix Director Director is a web-based tool that enables IT support and helpdesk teams to monitor an environment, troubleshoot issues before they become critical, and perform support tasks for end users. You can also view and interact with an end user’s session. Director offers: • • • •

A Details page that displays connection information and resource utilization. An Activity Manager page that allows helpdesk representatives to troubleshoot and resolve issues quickly. A Dashboard that provides a graphical summary of your environment in a central location. A Trends page that provides in-depth, graphical monitoring and troubleshooting of the entire deployment with various time ranges.

Server OS Machines With the Server OS machine model, a single server-based OS can host multiple desktops. The Server OS machine model provides a low-cost, high-density solution; however, applications must be compatible with a multiuser, server-based OS. In addition, because multiple end users share a single OS, they are restricted from performing actions that may negatively affect others. Example of such actions include: installing applications, changing system settings, and restarting the OS. A single end user may also consume too many resources, which may negatively affect others.

Desktop OS Machines With the Desktop OS machine model, each end user has a full desktop OS, which provides administrators with a granular level of control over the number of virtual processors and memory assigned to each desktop. You can deliver Desktop OS machines as: Random Desktops

Desktops in which end users are dynamically connected to one of the desktops in the pool each time they log on. Restarting the machine will lose changes to the desktop image.

Static Desktops

Desktops that assign a virtual desktop or allocate a virtual desktop to end users on first access. Once assigned, end users will always be connected to the same virtual desktop. Changes to the desktop image are lost when end users restart the machine, unless you implement persistent write cache or Personal vDisk (PvD).

PvD is a dedicated virtual disk attached to an environment and can add flexibility and persistence of end-user installed applications and end user settings. The PvD is merged along with the write cache.

Discussion Question Why would you use Random desktops over Static? Why would you use Static over Random?

18

Module 1: Supporting XenDesktop 7.x as a Helpdesk Representative

Virtual Delivery Agent (VDA) You must install the Virtual Delivery Agent (VDA) on any server or workstation-based OS used to deliver applications or desktops to the end user. The VDA incorporates functionality, applicable group policy, and Personal vDisk (PvD) settings. You cannot install the VDA from XenDesktop7 on Windows XP or Vista. You must use the VDA from XenDesktop 5.x

SQL Database After completing the authentication process, the Delivery Controller contacts the Microsoft SQL database to discover the machines and applications available to the end user. The SQL Server is a relational database and management system that you can install on a Windows server. A total of three databases store the following information: the Site, configuration logging, and statistical data for the implementation. By default, XenDesktop creates the required databases on the SQL Server.

NetScaler NetScaler provides a secure application access solution that brings granular application-level policy and action controls. NetScaler optimizes the delivery of applications over the Internet and private networks, combining application-level security, optimization, and traffic management into a single, integrated appliance.

Citrix License Server The Citrix License Server stores and manages the license files for all Citrix components within the XenDesktop architecture, with the exception of NetScaler components, which you manually configure with license files.

Hypervisor A hypervisor is a thin layer of software that allows you to allocate physical resources of a device amongst multiple virtual machines. These virtual machines reside on the hypervisor. Citrix administrators will use the hypervisor to manage resources and monitor the environment. XenDesktop supports several hypervisors, including: • • •

Citrix XenServer Microsoft Hyper-V VMware ESX

Discussion Question What are the benefits of hosting virtual machines within a hypervisor as opposed to using physical machines?

XenDesktop Infrastructure Now that you have an understanding of the XenDesktop 7.x components, below you will see each layer of the infrastructure and the basic flow of an end-user device as it accesses the environment.

User Layer

The user layer contains Citrix Receiver, regardless of whether the end user connects from an internal or external device.

Access Layer

The access layer contains the components that provide end-user access to the environment, Citrix NetScaler, and StoreFront. The NetScaler provides secure access and intelligent load-balancing for StoreFront, Delivery Controller, and related infrastructure. Internal end-user devices connect from the user layer to the access layer using Citrix StoreFront. In a Citrix-recommended implementation, external end-user devices connect first through Citrix NetScaler---and often a firewall and perimeter network---and then through StoreFront to access resources.

Control Layer

The control layer houses various controllers and infrastructure components required for managing and delivering virtual desktops. The control layer addresses decisions surrounding the management and maintenance of the overall solution. The control layer is comprised of access controllers, Delivery Controllers, and infrastructure controllers. Once an end-user connection moves past the access layer, Citrix StoreFront communicates with the Delivery Controller in the control layer.

Resource Layer

The resource layer contains the end user's virtual desktop and applications. It contains three components: applications, operating system image, and personalization, which contain the end-user profiles and policies.

Management Layer

The management layer contains all of the consoles and utilities used to configure and manage the XenDesktop components.

Port Utilization The following is a summary of the ports used by the components we have discussed throughout this module.

For more information about the ports used in a XenDesktop environment, see Citrix article CTX101810 at http://support.citrix.com.

Helpdesk Overview Helpdesk representatives solve a variety of issues for end users with the assistance of administrative tools. Every organization follows different policies and procedures. Yet when troubleshooting within an environment, you will find the methodology remains consistent. This section discusses the methodology and helps build your skills of documenting, troubleshooting, and resolving issues.

Support Levels and Responsibilities Tier 1 and tier 2 helpdesk administrators act as the first line of defense for IT support, though their roles vary between organizations. Many of the common tasks performed between the two levels include: • • • • •

Answering helpdesk calls and email queues. Following guidelines and procedures to troubleshoot common software, hardware, network, and telecom issues. Documenting and tracking end-user issues and resolutions. Providing onsite and offsite support. Monitoring the environment to help prevent potential issues from developing and becoming system-critical.

The boundaries for what a specific helpdesk tier can and cannot do depend on the size of the organization, whether the helpdesk provides dedicated support for Citrix components, and whether the helpdesk is the first-level entry point for all issues in an environment. This course will present tasks and utilities that some helpdesk teams may not have access to, while other helpdesk teams will be able to complete these tasks and more. This section provides the knowledge you need to understand the XenDesktop architecture and the communication flow between the components. This knowledge will enable you to diagnose and troubleshoot end-user issues.

Troubleshooting Methodology The diagram below outlines the troubleshooting methodology. You can use this troubleshooting methodology regardless of the product, components, or environment.

Defining the issue. Gathering detailed information. Considering the possible causes. Creating an action plan to address the issue. Implementing the action plan. Observing the results of the action plan. Documenting any changes following resolutions.

Each time you discover a new issue, the process will start from the beginning. Depending on your organization and the level of support you work in, you may have to escalate an issue before reaching the end of the methodology.

Defining the Issue Your first step in troubleshooting is to define the issue by analyzing general information to find the likely cause. Information is limited to the end user reports about their issues. You must create an issue statement, a concise and accurate summary of the known facts. Using an issue statement places the focus on the true issue and prevents you from troubleshooting any other out-of-scope issues.

Gathering Detailed Information Gathering detailed information involves reviewing helpdesk reports and investigating further if necessary using tools such as Citrix Director or Citrix Studio. This additional information should include data that serves to exclude other possible causes and helps to narrow the scope of the issue. 22

Use the following tasks to narrow the scope of the issue: Identify Symptoms

Further define the scope of the issue by identifying, categorizing, and documenting symptoms.

Reproduce the Issue

Attempt to reproduce the issue and obtain a clear representation of the environment.

Investigate the Timeline

Determine when the issue began and how often it occurs.

Determine the Scope of the Issue

The scope of the issue is the number of end users impacted or the extent to which it affects performance.

Check Baseline Information

Review historical data about the environment such as resource usage. This information can help determine if recent changes made to the environment may be at fault.

Considering Possible Causes The clues gathered from the investigation in the previous steps will help point to possible causes of the issue. Define the scope of the issue and create a list of possible causes. This list of possible causes assists in troubleshooting.

Creating an Action Plan Investigate each possible cause and create an action plan based on this information. The action plan may involve actions such as configuring the end-user device and investigating settings. When creating an action plan, you should consider how a repair to one component may cause another issue. Questions to consider include: • What is the scope of the change? • When will the change occur and how long will it take? • Who will be involved in the change? • Will the change occur in a controlled environment? • Is there a plan to roll back whatever changes you implemented, if needed? • In what ways does the test environment differ from the production environment? When creating an action plan, you should first test potential changes in a controlled environment. For example, if you suspect that memory optimization is the cause of an issue, you should test potential corrective actions, such as disabling memory optimization, prior to implementing them into production.

Implementing the Action Plan The next step is implementing the action plan, which could be an investigation leading to identifying additional action items or a full repair of the issue. When implementing action plans, Citrix recommends making only one change at a time. Also, it is best to make changes in small sets when situations require multiple simultaneous changes. This methodology helps to track the process and differentiate between successful and failed actions. Ideally, you should implement all changes in a test environment that mimics the actual environment. This will allow trial and error without consequences. You may even find unintended behaviors after implementing your solution in the test environment, another reason not to first implement in the actual environment.

23

Observing the Results of the Action Plan Observing results consists of monitoring the changes made to the environment during implementation. The issue may require more than one repair. You must observe each repair separately to ensure that the action plan does not create other issues. You must gather enough information to determine whether a change is effective, even when the action plan does not resolve the issue. If the repair is successful, move on to the next step of the Citrix troubleshooting methodology. Otherwise, you must investigate further and create another action plan.

Documenting Changes Following Issue Resolution Documentation is an integral part of troubleshooting and change control. Recording changes and, in some instances, the time these changes occurred provides valuable information for future reference. Before closing a case, you must document all troubleshooting steps and actions taken. In general, while working through the initial action plan, you should consider that changing something during the repair might impact the environment in some other way. Recording allows you to retrace and therefore undo those changes if needed. Documentation provides the following advantages: • • •

It explains exactly what was done to repair the issue, which can be helpful in repairing similar issues. It provides valuable historical information to colleagues. It includes troubleshooting steps and their results, which can reduce the likelihood of repeated actions and promote faster case closings with escalated issues.

Citrix recommends documenting all actions, including key information provided by the end user, as they occur. Doing so ensures you do not overlook vital information. In addition, when you document while troubleshooting, you save time after the helpdesk call that could go toward working with other end users. This workflow promotes efficient case management, resulting in quicker case resolutions.

Discussion Question In what instances has documentation saved you time or trouble? When have you tried to resolve an issue and not had proper documentation?

Troubleshooting Flowchart Problems can arise in multiple areas within an environment. Sometimes the issue may seem related to the virtualization aspect; however, you must properly configure many other components XenDesktop to function properly. Prior to escalation, ask the right questions to ensure that you escalate the issue to the appropriate group within your organization. Below is a flowchart that will help you rule out components by answering questions based on what is happening during troubleshooting. This is also available within a job aid in your Student Resource Kit.

Configuring Citrix Receiver and Using Citrix StoreFront In order to help end users through issues, you must know what the end user should experience in a properly working environment. This module will discuss that experience and give you an understanding of how Receiver and StoreFront work together to deliver applications and desktops to the end user. After completing this module, you will be able to: • • • • • • •

Discuss the logon process of an end user. Verify Delivery Controllers associated with stores. Install, configure, and reset Receiver. Access a desktop and open applications from Receiver. Verify the version of Receiver. Access Connection Center. Access and view event logs.

Module timing: 2 hours

Authenticating to the XenDesktop Environment Citrix StoreFront authenticates end users to XenDesktop sites, enumerating and aggregating available desktops and applications into stores that end users access through Citrix Receiver. StoreFront is the successor to Web Interface and was built on a modern, more flexible and powerful framework that enables StoreFront to provide next-generation features, such as: • • • •

A unified StoreFront that delivers Software as a Service (SaaS) & native mobile applications and XenDesktop resources. Simplified Account Provisioning, which enables end users to connect to assigned desktops and applications by simply entering their email or a server address, or by opening a provisioning file in Receiver. Access from any Receiver with a consistent end-user experience, including automatic fallback to an HTML5 client if a native client is not available locally and cannot be installed. Synchronization of resource subscriptions across all platforms and devices (Follow-me Apps & Data).

Understanding StoreFront Components StoreFront has several key parts that perform specific functions. You must gain an understanding of each in order to better troubleshoot issues reported by the end user. An issue could arise specific to each component. StoreFront Server

The StoreFront server locally records application subscriptions, shortcut names, and locations. When an end user accesses a store, the application synchronization feature automatically updates the subscribed applications on the end-user device to match the configuration stored on the StoreFront server. The Store Service retrieves the credentials to authenticate to XenDesktop, ensuring that end users have a consistent experience across all devices.

Authentication Service

This service authenticates end users to XenDesktop sites. Built-in Windows security features store the credentials, so the end user only needs to log on once.

Store

The store authenticates end users to the components providing the resources. The store also enumerates resources available from XenDesktop sites and the Delivery Controller (SaaS applications). End users access the store through Citrix Receiver or Receiver for Web.

Receiver for Web site

This site enables end users to access stores through a web page. The site can verify the installed version of Receiver and guide the end user through an upgrade or installation process. For scenarios in which end users cannot locally install Receiver, they can use HTML5 Receiver.

Understanding the Authentication Process

1. 2.

3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.

30

An end user enters a username and password into Receiver, which sends the information to the StoreFront server (end users may skip this step if an administrator already configured pass-through authentication). The authentication service of StoreFront retrieves the end-user credentials and validates them with a domain controller. The StoreFront server must be a member of the same Active Directory forest as the end-user account and the accessed resources. StoreFront retrieves the end-user’s application subscriptions locally and loads them into memory. StoreFront forwards the end-user credentials as part of an XML query to the Delivery Controller. The Controller validates the end-user credentials with a domain controller. After successful validation, the Controller checks which resources in its database it has already published to the end user. The Controller sends an XML response to StoreFront containing all resources available to the end user. StoreFront sends the list of available resources including the existing subscriptions to the Citrix Receiver or displays them in the Receiver for Web. The end user requests a resource. Receiver sends the request to the Controller, which starts the broker service. The broker service finds a machine to fulfill the session request and powers it on if needed. The Controller sends the connection details to the StoreFront Server. The StoreFront Server sends the information in an ICA file to the Receiver client on the end-user’s device. Receiver client launches a connection to the server hosting the resource.

Understanding Citrix Receiver Citrix Receiver is a universal software client that provides secure, high-performance delivery of virtual desktops and applications. Citrix Receiver provides: • • • •

Self-service access to virtual desktops, applications, and IT services. A high-definition experience on any device. Instant updates to end users with IT control and visibility. Easier management of Enterprise data, apps, desktops, and SaaS apps through a secure, centralized deployment.

Receiver handles the ICA extension, a file that contains details such as session properties and establishes a connection between the end user and the remote server. End users receive the ICA file when they request an application or desktop. You will first learn how to configure Receiver manually. You can also push a configuration file to the end user.

Installing Receiver from Citrix.com An end user downloads the CitrixReceiver.exe package from Citrix.com. During the installation, the end user can set up an account using an email address or a server URL. This is sometimes referred to as Receiver for Desktop. End users will want to install this version when they are able to establish a secure connection to the network, such as VPN from their work-issued physical machine. Citrix has a Receiver download site that will detect the end user's OS and offer the appropriate install package. This is one of the fastest and simplest methods of deployment. This version of Receiver may be newer than the version offered from the StoreFront server. Different versions may have different features or menus.

To Install Receiver from Citrix.com 1. 2. 3.

Log on to the machine you will perform the installation on. Open Internet Explorer. Type http://receiver.citrix.com. The site will auto-detect the endpoint OS and offer the appropriate installation package.

Discussion Question Can you make a connection from an endpoint to a XenDesktop resource without installing Receiver installed on the endpoint? Why?

Navigating Receiver Citrix Receiver can be accessed from a device or from a browser. In both cases, the Receiver client and Receiver for Web act as gateways to the internal corporate network, requiring the end user to sign in. Once signed in, the end user can customize Receiver with the applications and virtual desktops needed to work on site or remotely.

Launching Applications and Desktops The end user can customize which applications and desktops appear in the dashboard upon logging in. Receiver will stream these to the end user's device. In many cases, the end user can add an application in Receiver faster than installing it locally. The end user's hardware does not limit the performance of streamed applications. The end user can also stream virtual desktops if the administrator has designated appropriate machines in the desktop OS machine catalogs. These virtual desktops can run as separate windows on the end-user's device. For example, the end user can run multiple desktops for code testing or a separate desktop OS in each window. Receiver allows end users to add desktops to access machines remotely or from their own device.

Troubleshooting Receiver Issues Since end users frequently access resources through Receiver, you may first want to investigate Receiver connectivity. Sometimes, a difference in software versions might explain why two end users are not experiencing the same issue. Other times, an incorrect Store URL could mean that one end user sees applications for a different group or office. Citrix offers a set of tools to analyze the environment for these variables.

Verifying the Version of Receiver End users may not have access to certain features of Receiver if they do not have the appropriate version. Verifying which version of Receiver the end user has will quickly help you determine if this could be the cause of the problem.

Researching Issues Using Citrix Studio Citrix Studio is the console that enables you to configure and manage your deployment, eliminating the need for separate consoles to manage the delivery of applications and desktops. Studio provides various wizards to guide you through the process of setting up your environment, creating workloads to host applications and desktops, and assigning them to end users. Administrators will primarily use this console for monitoring and managing the environment, however this module will give you a better understanding of how the environment works on the back end. After completing this module, you will be able to: • • • • • •

Create an administrator with a role and scope pair. Enable and disable Maintenance Mode on machines. Verify the state of a virtual machine within a machine catalog. View, edit, and configure policies. Create and edit machine catalogs and Delivery Groups. Run the Policy Modeling report to investigate policy conflicts.

Module timing: 3 hours

Working with Delegated Administration The delegated administration model uses role-based and object-based control to offer customized permissions to match the roles in your organization. Delegated administration uses three concepts: administrators, roles, and scopes.

Working with Administrators An administrator can be a single entity or group identified by a corresponding Active Directory account. Each administrator is associated with one or more role and scope pairs, allowing organizations to create administrative functions to match job roles.

Working with Roles Roles represent a job functions. XenDesktop has the following built-in roles: Full Administrator

Performs all tasks and operations. A Full Administrator has the All scope by default.

Machine Catalog Administrator

Creates and manages machine catalogs. This role can manage base images and install software, but cannot assign applications or desktops to end users.

Delivery Group Administrator

Delivers applications, desktops, and machines; manages associated Delivery Group sessions and also settings for policies and power management.

Host Administrator

Manages host connections and their associated resource settings. This role cannot deliver machines, applications, or desktops to end users.

Help Desk Administrator

Views Delivery Groups and manages their sessions and machines. Sees the machine catalog and host information of the active Delivery Groups and performs session and machine power management for the machines in those Delivery Groups.

Read-only Administrator

Reads all objects in specified scopes as well as global information, but cannot modify settings.

Working with Scopes A role defines a set of permissions, while a scope defines what objects the role has control over. Scopes, group objects in a logical way that reflects your organization. Objects refer to desktops, Delivery Groups, machine catalogs, and hosts (for example, XenServer or vSphere). Different scopes may share the same objects. The All scope grants the Full Administrator control over all objects. You can also create scopes when you create a new administrator; you must associate each administrator with at least one role and scope pair. When you are creating or editing desktops, machine catalogs, applications, or hosts, you can add them to an existing scope. If you do not add them to a scope, they remain part of the All scope. You cannot use a scope to enable an administrator to create a Site, nor can a scope contain other roles and scopes; however, those objects are included in the All scope. You cannot directly scope machines, power actions, desktops, or sessions. You can grant administrators permissions over these objects through the associated machine catalogs or Delivery Groups.

Tracking Administrator Activity The Logging node in Studio records changes made by all administrators. This information is valuable for investigating whether reported issues came before or after the last administrative changes made in Studio. The logs show time stamps next to change. If an end user reports an issue at the start of your shift, check the Logging node to see what changes made by a previous administrator might have caused the issue. Document the time stamps and logged actions when troubleshooting. Studio records changes made to: • • • • •

Machine catalogs Delivery Groups (including changing power management settings) Administrator roles and scopes Host resources and connections Citrix policies through Studio

Examples of recorded activity include: • •

Power management of a virtual machine or an end user's desktop. A message sent to an end user through Studio or Director.

Working with Machine Catalogs A machine catalog is a collection of virtual machines or physical computers that you can manage as a single entity. Machine catalogs specify the virtual machines or computers available to host applications or desktops, the Active Directory computer accounts assigned to those virtual machines or computers, and in some cases, the master image that is copied to create the virtual machines. Aside from Studio, Citrix offers two methods of creating machine catalogs: Machine Creation Services (MCS)

MCS enables the rapid creation of machine catalogs based off a single master image. Since the master image contains a single OS and settings, MCS can provision identical VMs and place them in their own catalog. MCS will also create corresponding machine accounts in Active Directory. The power of MCS is in its ability to update the master image and replicate the changes to the provisioned VMs.

Provisioning Services (PVS)

PVS also enables the rapid creation of machine catalogs, but might be better suited for larger deployments and for storage performance considerations such as IOPS limitations. With PVS, you can start new VMs using PXE or BDE services and add them to a catalog specified in the PVS console. Like MCS, you can update the single master image and replicate changes to the members of your machine catalog.

Creating and Viewing a Machine Catalog An administrator with the appropriate role and scope can create machine catalogs in Citrix Studio. If an OU needs to stream applications, you can create a machine catalog of server-based OS machines. If another OU needs desktops served as random sessions, you can create a machine catalog of desktop-based OS machines. A machine catalog cannot contain mixed-OS machines. You cannot add a desktop-OS machine to a catalog of server-OS machines. If the end user calls Helpdesk and reports a missing application or desktop, try viewing the catalog to determine if the hosting machine is down for maintenance. Viewing the catalog can give insight into the machine's status. For example, a machine hosting desktops could be down due to power failure or put into Maintenance Mode by another administrator to receive hotfixes.

To Create and View a Machine Catalog 1.

Log on to the Controller machine that has Citrix Studio installed on it.. Log on to the XDC-001 machine using the TRAINING\Administrator and Password1 credentials.

Discussion Question Why would an application or desktop appear to the end user but fail to launch? If the machine does not register with the controller, why does the application or desktop still appear?

Working with Delivery Groups Delivery Groups tell you which end users should have access to certain resources. For example, an Accounting Delivery Group may only need access to Microsoft Office and accounting software, whereas an Engineering Delivery Group may need access to machine catalogs hosting CAD software. The machine catalogs might have a one-to-one relationship with their Delivery Groups.

Creating Delivery Groups You can edit a Delivery Group to manage power settings for the machines, such as: • •

46

Days and times to turn off machines. The delay (in minutes) before suspending any disconnected machine for peak hours and off-peak hours.

Module 3: Researching Issues Using Citrix Studio

The behavior of machines after they disconnect from all sessions: nothing, suspend, or shut down.

When you want to investigate the status of a machine, check to see if an administrator had previously configured these settings. You cannot create Delivery Groups from machine catalogs with different machine types. For example, a Delivery Group cannot mix machines from a Server OS catalog with a Desktop OS catalog.

Discussion Question How would you handle a request that asks you to provide access to a Windows 8 machine catalog and a Server 2012 machine catalog for one group of end users?

Enabling and Disabling Maintenance Mode Administrators can use Citrix Studio to put a machine into Maintenance Mode before applying updates. This mode prohibits connections to the machine. No end user can log on to a machine in this state. Maintenance Mode takes effect as soon as end users log off. If they try to connect to a machine in Maintenance Mode, a message will report the machine is currently unavailable and to try reconnecting. Check with an administrator if a machine no longer requires Maintenance Mode, so you can turn off this mode to make the machine available.

To Enable or Disable Maintenance Mode 1.

Log on to the Controller machine that has Citrix Studio installed. Log on to the XDC-001 machine using the TRAINING\Administrator and Password1 credentials.

2. 3.

Open Studio. Locate the machine or desktop group to put into Maintenance Mode. Click Search and select the XDW-Acct-01.TRAINING.lab desktop OS machine. If you do not see the machine, make sure to clear the search filter then click the Desktop OS Machines tab.

Registered and Unregistered States A virtual machine must register with the Controller to be accessible to end users. Unregistered machines may not be available to end users accessing the corresponding Delivery Groups. An incomplete VDA installation is a typical cause for a machine failing to register. The event log of a VDA machine is a good place to look for registration issues. The log should show which Controllers the VDA machine is trying to register with and why registration attempts are failing.

To Check the State of a Virtual Machine 1.

Log on to the Controller machine that has Citrix Studio installed Log on to the XDC-001 machine using the TRAINING\Administrator and Password1 credentials.

2. 3. 4. 5.

Open Studio. Click the Delivery Groups node. Select HR User Desktops . Scroll the Details tab below and verify the states of machines under the State column to the right. There could be one registered machine and two total machines. Recall that you may have turned on Maintenance Mode in the previous lab task.

Understanding Citrix Policies After creating machine catalogs and Delivery Groups, you can personalize the end-user experience with Citrix policies. You can create policies for specific groups of end users, devices, or connection types. Each policy can contain multiple settings, which you can merge. A prioritization system minimizes the chances of conflict between settings. For example, you can configure settings to: • • • •

Control sound quality for end-user devices. Allow end users access to the Documents folder on their local machines. Allow or prevent remote end users from being able to save work to their hard drives. Allow or prevent end users access to the system clipboard.

With policies you can apply different profile behaviors to the machines in each Delivery Group. For example, one Delivery Group might require Citrix mandatory profiles, whose template is stored in one network location, but another Delivery Group might require Citrix roaming profiles stored in another location with several redirected folders. You can manage Citrix policies through Group Policy in Windows or from Studio. The console or tool you use depends on whether you have the appropriate permissions to manage policies, where you want to store them, and how you plan to maintain them. The site database stores Citrix policies. The database also pushes updates to the end-user session, either when the machine registers with the Controller or when an end user connects to a resource. Before you create a policy, decide which group of end users or devices you want it to affect. You may want to create a policy based on job role, connection type, device, or geographic location. By default, Citrix provides Unfiltered policies for Computer and User policy settings. If you use Active Directory Group Policy Editor to manage Citrix policies, settings applied to the Citrix Unfiltered policy will apply to farm servers and connections that fall within the scope of the Group Policy Objects containing the Unfiltered policy. If you use Studio to manage Citrix policies, settings added to the Unfiltered policy affect servers and connections in the farm.

Creating and Viewing Citrix Policies You can apply policies at different levels: OU, domain, local machine, XenDesktop Site, and local system-level. Prioritization determines the order in which the environment processes Citrix Policies and Microsoft GPOs. Policy settings applied at one level may conflict with settings another level.

49

When creating a policy, you will specify a filter and settings. The filter defines the objects affected by the policy, while the settings contain the specific rules of the policy. For example, a printing policy may specify that all objects (filter) within an OU retain the last installed printer as the default printer (settings). View policy details in Studio when you suspect there are policy conflicts. Documenting policy details can assist others during issue escalation. These are not the same as Group Policy Objects (GPOs), which an Active Directory administrator typically configures.

Understanding End-User Profiles An effective profile strategy improves network performance and the end-user experience by providing end users with faster logons, retained application setting and customized printers, and reduced administrative overhead. Designing this profile strategy requires analyzing end users' needs. Some important questions to ask: • • •

Do end users require streamed applications? Are desktops random or static? What percentage of end users are remote workers? How often do end users install their own printers?

The following are some common profile types: Local Profiles

The XenDesktop server stores local profiles and initially creates them based on the default profile. End users retain changes to their local profile on each individual server, but changes are only accessible for future sessions on that same server. Local profiles require no configuration.

Roaming Profiles

The site stores these profiles in a centralized network repository. Roaming profiles differ from local profiles, being available to end user sessions accessed from all XenDesktop servers in the environment. The first time the end user logs on to a XenDesktop server, the server creates the roaming profile based on the default profile. During logoff, the server copies the profile to a network location.

Mandatory Profiles

Sometimes called roaming mandatory profiles, the site also stores these in a centralized network location for each end user. They differ from roaming profiles by not retaining the end user’s changes at logoff.

Citrix Profile Management

This is a unique profile type that supersedes all other profiles. It addresses “last write wins” issues by only capturing changes within the profile, rather than writing the entire profile at logoff. This strategy minimizes conflicts that result from making profile changes when accessing multiple XenDesktop servers.

Understanding Citrix Profile Management Citrix Profile management allows end users to customize their virtual and physical desktops, applications, and server settings. Managed through Citrix policies or GPOs, Profile management provides a central point of configuration and control to give a consistent experience regardless of which machine hosts the end-user session.

52

Module 3: Researching Issues Using Citrix Studio

Citrix Profile management provides end users with fast logons and logoffs. The following steps describe how Citrix Profile management delivers a profile to the end user: 1. 2.

3. 4. 5.

The end user starts a session for a machine with Profile Management enabled. The Citrix Profile management service determines if the end user is a member of the processed group defined in the profile management policies. If the end user is a member, the service attempts to load the appropriate profile from the store. If the end user is not a member, a Microsoft profile is assigned. Profile management verifies that the store contains the profile. If a profile is not found on the store, the service migrates the end user's Microsoft profile to the store or creates a new one from a template specified in the policy. Profile management streams a local profile from the store to the virtual machine. Profile management monitors the end user's profile and logs any changes back to the end user's profile store. By default, Citrix Profile management installs silently on master images when you install the VDA. For more information about Profile Management best practices, see http://support.citrix.com/article/CTX136376

Configuring Profile Management Settings A sound profile strategy requires the right policy settings to optimize performance and the end-user experience. With XenDesktop 7, Citrix Profile Management installs silently during the VDA installation. You can enable the Profile Management policy through Studio and apply these commonly used settings: Enable Profile Management

You must first configure and enable this setting to enable the Profile Management policy.

Active Write Back

Traditional profile management faces the issue of "last write wins," meaning the NTUSER.DAT file stores system settings modified during each session and overwrites the version of the file on the network. With multiple active sessions, the NTUSER.DAT file saves settings for the last session to end, overwriting changes made during the previous sessions. Active write back addresses this by merging changes across all sessions and writing once to the NTUSER.DAT file.

Path to User Store

If enabled, the system stores end-user settings on the Store. The path can be relative to the home directory, a UNC path to a server share, or not configured. If disabled, the system stores settings in the Windows subdirectory of the home directory.

Profile Streaming

Reduce logon times by enabling this setting to stream files and folders only when accessed by the end user.

Exclusion List Setting

By default, Profile Management excludes some Microsoft system folders and roaming folders from syncing. You can configure this setting to exclude more folders or individual files from synchronizing with the end user's Store.

Inclusion List Setting

By default, Profile Management syncs folders and files within the end user's profile. With this setting enabled, Profile Management synchronizes the folders you've specified with a location on the end-user Store. Add folders outside the end user's profile or on the excluded folders list.

Profile Management processes domain profiles, not local accounts.

For more information about including and excluding files and folders from synchronization, see http://support.citrix.com/proddocs/topic/user-profile-manager-sou/upm-include-task-den.html.

Redirecting Folders Folder redirection is fundamental to any successful profile strategy. If storage space on the network is scarce, you may want to store only essential files on the network. End users can store Downloads, Pictures, Favorites, and personal files locally, while you might redirect Documents to a network location. A redirected folder is a persisting folder, because data is preserved after the end user session is over.

Troubleshooting Policies There may be many policies applied at multiple levels, such as site, domain controller, and organizational unit. The combination of Citrix and Microsoft policy settings creates a complex scenario. Conflicts can arise and often times it is because of the policy precedence and the order in which the session processes these settings.

Running the Citrix Policy Modeling Report Citrix Studio enables you to validate policies applied to the end user and corresponding machine of a session. When you suspect a reported issue to be caused by policy conflicts, you can run the Policy Modeling Report to check for conflicting settings. Document any conflicts to help the site administrator investigate the issue. You can run a similar tool from Microsoft, called Resultant Set of Policy (RSoP), from the Microsoft Media Console (MMC) or Active Directory. RSoP will only display Microsoft policies, while Policy Modeling in Studio displays both Citrix and Microsoft policies. You will be using Policy Modeling to view both types. For more information about Resultant Set of Policy, see http://technet.microsoft.com/enus/library/cc782615(v=ws.10).aspx

To Run the Citrix Policy Modeling Report 1.

Printing in a XenDesktop 7 Environment Printing is an important aspect of every Citrix infrastructure, but it is sometimes misunderstood and can be a common cause of issues. XenDesktop offers a variety of features that enable organizations to successfully integrate printing in almost any scenario. In this module you will first review the overall printing architecture in a virtualized environment and then consider other printing concepts. After completing this module, you will be able to: • • • •

Describe printing concepts. Describe the default printing behavior in XenDesktop. Alter the default printing behavior. Troubleshoot end-user printing issues.

Module timing: 2.5 hours

Printing Concepts In a virtualized environment, XenDesktop redirects print jobs through the network print server or end-user device to the printing device. When an end user prints, XenDesktop: • • •

Determines what printers to provide to the end user. This is known as printer provisioning. Restores the end user's printing preferences. Determines which printer is the default for the session.

The following concepts are crucial to understanding how printing in a virtualized environment works: Printer

A logical representation of a print device. A printer can be connected to a server, a client computer, or directly to a network.

Print Server

A computer on the network dedicated to managing printers on the network. The print server can be any computer on the network. Responsibilities include spooling, despooling, and managing and prioritizing print jobs.

Printer Driver

A program designed to allow other programs to work with a particular printer without involving the specifics of the printer's hardware and internal language.

Print Spooler

The Windows service and collection of dynamic link libraries (DLLs) that accepts a document sent to a printer by an application, then stores it on disk or in memory until the printer is available to process the job. This software receives, processes, schedules, and distributes documents for printing.

Spooling

The process of the printer driver taking device-independent commands from an application and formatting them into the device-specific format of a particular printer.

Print Queue

A group of documents waiting to print.

Citrix Universal Print Server

A server that provides universal printing support for network printers. The Universal Print Server uses the Universal Printer Driver, which enables you to use a single driver to allow network printing from any device.

Citrix Universal Printer Driver

A single driver installed and configured on the server to which an administrator can assign all auto-created client printers.

For more information about Windows and Citrix printing concepts, see Citrix article CTX111967 at http://support.citrix.com.

Printer Types In a Windows environment, there are two types of printers: local printers and network printers. With XenDesktop there is also the redirected client printer. The type of printer determines where the print metafile containing the print job is spooled. Understanding where the job is spooled can be useful should an issue arise. Local (Client and Server)

Local printers are connected to an end-user device or server. By default, the local OS directly spools the print job to a Windows end-user device or server.

Network (Client and Server)

Network printers are connected to a print server and the server OS directly spools the print job to the print server.

Redirected Client

Printers are connected to the end-user device using an UNC path or a cable. The server OS spools the print job to the end-user device.

Discussion Question Which type of printing do you use within your organization and why?

Default Printing Behavior By default, if you do not configure any policy rules, XenDesktop printing behavior is as follows:

The Universal Print Server is disabled. All printers configured on the end user device will automatically create at the beginning of each session. This behavior is equivalent to configuring the policy setting Auto-create client printers with the Auto-create all client printers option. XenDesktop routes all print jobs queued to printers locally attached to end-user devices as client print jobs (over the ICA channel and through the end user device). XenDesktop routes all print jobs queued to network printers directly from Server OS or Desktop OS machines. If XenDesktop cannot route the jobs over the network, it will route them through the end-user device as a redirected client print job. This behavior is equivalent to disabling the policy setting Direct connection to print servers. XenDesktop attempts to store printing properties, a combination of the end user’s printing preferences and printing device-specific settings, on the end-user device. If the client does not support this operation, XenDesktop stores printing properties in end-user profiles on the client's machine. This behavior is equivalent to configuring the policy setting Printer properties retention with the Held in profile only if not saved on client option. XenDesktop uses the Windows version of the printer driver if it is available on the end user machine. If the printer driver is not available, XenDesktop attempts to install the driver from the Windows operating system. If the driver is not available in Windows, it uses a Citrix Universal printer driver. This behavior is equivalent to enabling the policy setting Automatic installation of in-box printer drivers and configuring the Universal printing setting with the Use universal printing only if the requested driver is unavailable.

Printing Policies When end users access printers from published applications, you can configure Citrix policies to specify: • • •

How printers are provisioned (or added to sessions). How print jobs are routed. How printer drivers are managed.

You can have different printing configurations for different end-user devices, end users, or any other objects on which policies are filtered. Configuring Citrix Printing policies will allow you to manage most printing functions. Printing settings follow standard policy behavior. By default, the system stores printer properties on the hard disk or in the end-user profile. When an end user changes printer properties during a session, the profile on the machine updates and saves those changes. The next time the end user logs on or reconnects, the end-user device inherits those retained settings. That is, printer property changes on the end-user device do not impact the current session until the end user logs off and then logs on again.

Altering the Default Printing Behavior You can alter the default printing behavior in the environment using policies. Altering the printing behavior can affect the performance of printing in the environment and the end-user experience. There are several ways to configure printers for use in a session. When configuring printers, carefully consider the following items: • • • • • •

Available printing options Types of printer drivers Printing environment End-user requirements Administrative requirements Business needs Prior to changing the default printing behavior using policies, you should study basic XenDesktop printing concepts such as printer types, printing security, printer provisioning, printing pathways, and printer driver behavior to ensure the implemented changes are successful.

To Alter the Default Printing Behavior 1.

Discussion Question When should you use the Citrix Universal printer driver in a XenDesktop environment?

Provisioning Printers The process by which XenDesktop makes printers available in a session is known as provisioning. Printer provisioning for XenDesktop is typically handled dynamically. Virtual machines will not store the printers that appear in a session. Instead, policies assemble the printers as the session is built during log on and reconnection. As a result, the printers can change according to policy, end-user location, and network changes. This means that end users who roam to a different location might see changes to their workspace.

62

XenDesktop also monitors client-side printers and dynamically adjusts in-session auto-created printers based on additions, deletions, and changes to the client-side printers. This dynamic printer discovery benefits mobile end users as they connect from various devices. The sections below provide configuration information for the different XenDesktop printer provisioning methods.

Auto-Creating Client Printers XenDesktop uses auto-creation to create printers at the beginning of each session, depending on which printers the end-user device defines and which policies apply to that session. By default, XenDesktop makes session printers available by automatically creating all printers configured on the end-user device, including locally attached and network printers. After the end user terminates the session, the printers disconnect from that session. The next time a session starts, XenDesktop evaluates the printer creation policies and enumerates the appropriate printers on the end-user device. You can change the default auto-creation settings to limit the number or type of auto-created printers. XenDesktop can autocreate locally defined client and network printers. XenDesktop includes these universal printing solutions for client printers: Citrix Universal Printer

A generic printer created at the beginning of sessions that is not tied to a printing device. The Citrix Universal Printer does not need to enumerate the available client printers during logon, thereby reducing resource utilization and decreasing logon times.

The Universal Printer can print to any client-side printing device.

Citrix Universal printer drivers

A device-independent printer driver that supports advanced printer functionality, such as stapling and sorting. If you configure a Citrix Universal printer driver, XenDesktop uses the EMF-based Universal printer driver by default.

Controlling Client Printer Auto-Creation At the start of a session, XenDesktop auto-creates all printers on the end-user device by default. You can control which, if any, types of printers are provisioned to end users and can prevent auto-creation entirely. The Auto-create client printers policy rule allows you to control printer auto-creation. Located in the Citrix Policies node of the Group Policy Management Console or the Policies node of Studio, with this rule you can: • • • •

Prohibit printers visible to the end-user device from auto-creation. Automatically create only the default printer for the end-user device. Automatically create all non-network printers (such as LPT, USB, TCP) defined on the end-user device. Auto-define all printers visible to the end-user device, including network and locally attached printers, at the start of each session.

To Control Client Printer Auto-Creation 1.

Log on to the Controller machine that has Citrix Studio installed. Log on to the XDC-001 virtual machine using the TRAINING\Administrator and Password1 credentials.

2. 3.

Open Studio. Select the Policies node. Click Close if the Citrix Policies Welcome screen appears.

Enter a name for the policy and verify that Enable policy is selected. Enter Auto-create client default printer only - Acct in the Policy name field and verify that Enable policy is selected. 14. Click Finish.

Session Printers By default, XenDesktop automatically creates network printers on the end-user device at the beginning of a session. By specifying the network printers you want to create for each session, XenDesktop allows you to reduce the number of enumerated and mapped printers. These specified printers are called session printers. You can filter session printer policies by IP address to provide proximity printing. Proximity printing enables end users within a specified IP address range to automatically access the network printing devices that exist within that same range. Citrix Universal Print Server provides proximity printing.

Enter Session Printer - Acct in the Policy name field and verify that Enable policy is selected. 14. Click Finish.

End User Self-Provisioning End users may need printers that are not auto-created at the beginning of their sessions. By default, end users can add network or client-defined printers in their sessions using the Windows Add Printer wizard on the server or an application that lets them browse to the printers.

Auto-Retained Printers Auto-retained printers are those in which end users add through user self-provisioning. Auto-retained printers are created again (or remembered) at the start of the next session and route print jobs along the client printing pathway. Auto-retained printers appear in the session on the end-user device until deletion of the client printer within the session is done manually. This will remove the remembered printer connection from the properties store of the end-user device. An auto-retained printer will show the notation "Auto Retained" in the Comment field of the printer properties. You can prohibit auto-retained printers from auto-creating at the beginning of a session using the Retained and restored client printers policy rule in the policies node of Studio or the Citrix policies node of the Group Policy Management Console.

Printer Drivers You must install the respective print driver in order to print on a print device. If the print device is changed, then you must install a new or updated driver. In large organizations with hundreds of printers, managing printer drivers can become an intensive management task.

Citrix recommends that you never update a printer driver. Always uninstall a driver, restart the print server, and then install the replacement driver. This helps ensure consistency and decreases the chance that issues with existing drivers are transferred to the updated drivers.

Citrix Universal Print Server The Citrix Universal Print Server provides universal printing support for network printers. The Universal Print Server uses the Universal printer driver, a single driver on a Server OS or Desktop OS machine that allows local or network printing from any device, including thin clients and tablets. When you enable the Citrix Universal Print Server, all connected network printers use it automatically through autodiscovery.

Universal Printer Driver To simplify printing in XenDesktop environments, Citrix recommends using the Citrix Universal printer driver. The Universal printer driver supports any print device, simplifying administration by reducing the number of required drivers. The Universal printer driver supports advanced printer functionality, such as stapling and sorting, and does not limit color depth. The Universal printer driver consists of two components: Server component

On a XenDesktop-based virtual desktop, the Universal printer driver is installed as part of the XenDesktop VDA installation. When a print job is initiated, this driver records the output of the application and sends it, without any modification, to the end-user device with the ICA/HDX connection.

Client component

The client component of the Universal printer driver is part of the Citrix Receiver installation. It receives the incoming print stream for the virtual desktop and forwards it to the local printing subsystem to render the print job using the device-specific printer driver.

It is important that if you support standard drivers in addition to the Citrix Universal printer driver, you should determine: • • •

Which types of drivers you can support. Whether to install printer drivers automatically when they are missing from machines. Whether to create driver compatibility tests.

If the Citrix Universal printer driver is not an option in your environment, you can map printer drivers to minimize the amount of drivers installed on the machines. In addition, mapping printer drivers enables you to: • • • •

Allow specified printers to use only the Citrix Universal printer driver. Allow or prevent printers to be created with a specified driver. Substitute good printer drivers for outdated or corrupted drivers. Substitute a driver that is available on a Windows server for a client driver name.

Configuring the Universal Print Server You must enable the Universal Print Server to use it with a Windows-native driver. The Universal Print Server selects a Windows-native driver by default, or it can fall back on the Universal printer driver. You can modify this behavior to select only one driver type by configuring the Universal print driver usage setting.

To Configure the Universal Print Server 1.

Log on to the controller machine that has Citrix Studio installed using domain administrator credentials. Log on to the XDC-001 virtual machine using the TRAINING\Administrator and Password1 credentials.

Troubleshooting End-User Printing Issues

You will likely need to ask several questions before you can begin to narrow the list of possible issues that are the root cause of any printing problem. The graphic shows some of the typical questions you may need to ask and how to proceed with your investigation . If during your investigation you realize that you need additional information that an end user cannot provide, for example, if you need to find out which printer drivers are in use, you can use a tool like Citrix Print Detective.

Running the Citrix Print Detective Tool Print Detective is a utility that can be used to gather printer driver-related information as part of the troubleshooting process. Print Detective: •

Reinforcement Exercise 1: Setting the Default Printer This exercise does not provide step-by-step instructions. Apply the concepts you just learned in this module to solve the problem. In most instances, the default value or choice will be the best choice, but you should explore other solutions whenever possible. If you have a question or get stuck, ask the instructor or a fellow student for assistance. In this module, you learned how to: • • • •

Describe printing concepts. Describe the default printing behavior in XenDesktop. Alter the default printing behavior. Troubleshoot end-user printing issues.

Approximate time to complete: 15 minutes You have received calls from several members of TRAINING's HR team stating that their default printer keeps changing daily and sometimes more than once a day. This is not the behavior intended in your XenDesktop environment. Instead, the HR team should have the Canon InkJet E600 printer as their default printer at all times. To complete your objective: • •

Check the printing policies in Studio to ensure that the appropriate policies are in place. Make note of any issues you find with the policies as currently configured.

As you investigate, remember to follow the troubleshooting methodology and document your findings during this exercise. Based on the results of the investigation, ensure that relevant policies are in place and correctly configured so that members of TRAINING's HR team always have the Canon InkJet E600 as their default printer.

Approximate time to complete: 15 minutes Recently, an administrator decided to restrict the automatic installation of printer drivers in the XenDesktop environment. However, after a few days, you began receiving calls from end users stating that their printers were not appearing in their sessions. Today, an end user from TRAINING's Accounting team called you and explained that she was unable to find her printer (Canon 9500 Accounting) after launching a published application. To complete your objective: • • • •

Verify the that the Canon 9500 Accounting printer is not available within application sessions. Review policies to see how the administrator restricted the automatic installation of printer drivers in the environment. Ensure that end users on the Accounting teams can print to their local printers. Following the troubleshooting methodology, investigate any reported errors or events.

Based on the results of the investigation, ensure that relevant policies are in place and configured correctly.

Discussion Question If an end user waits a long time for the desktop to load, where would you look within Director to find the problem? What could be possible causes?

Interacting with the End User You may need more information on an issue after reviewing an end-user's complaint. Director gives you the ability to send messages to the end user and also shadow the end user to view the problem and possibly correct the error remotely.

Sending a Message to an End User You can send messages to end users (or as a group message) to inform them about desktop maintenance or to communicate individually. For example, you may want to tell end users to log off before critical maintenance is about to take place to ensure they save their work, preventing loss of data.

To Send a Message to an End User 1.

Log on to the Helpdesk-PC computer. Log on to the Helpdesk-PC machine using the TRAINING\HelpdeskAdmin and Password1 credentials.

2.

Log on to Director using Internet Explorer. Browse to https://stf-001.TRAINING.lab/director and log on with HelpdeskAdmin, Password1, and TRAINING credentials.

The selected end user must have an active session running in order to receive the message. If the end user disconnects or the session times out, the message will not reach the recipient.

Shadowing an End-User Session Director allows you to shadow a XenDesktop session while assisting an end user. When shadowing, you are using the Microsoft Remote Assistance client, which allows you to view and work on the virtual machine of an end user whom you are assisting. You can also request that the end user allow you to share control of the keyboard and mouse. The system running Director, usually the Helpdesk Agent's desktop, must have the Microsoft Remote Assistance client installed. In addition, the virtual desktop must also have remote assistance enabled, either through the Virtual Delivery Agent Installation Wizard or through an Active Directory GPO. By default, only local administrators on the virtual desktop, including domain administrators, can launch a shadowing session. To provide shadowing access to Helpdesk administrators, you must configure an Active Directory GPO to add those administrators as remote assistance users.

Module 4 Reinforcement Exercise 1: Setting the Default Printer 1.

2.

Students should check these policies: • Default printer: set so that the default printer is the client's main printer • Session printers: set so that a list of printers uses the UNC convention • Wait for printers to be created: Disabled • Auto-create client printers: Do not auto-create client printers • Direct connections to print servers: Enabled Students should note that TRAINING has disabled client printer auto-creation and assigned network printers using the Session Printers policy rule. Based on that, they can select and set one of the configured session printers to be the default printer during end-user sessions using the Default Printer policy rule. Whichever selection they make will then persist for subsequent ICA sessions. It is important to note however, that if the end user selects in session a different printer to be the new default printer out of the pool of Session Printers available, that selection will be lost after session logoff. This is by design. For more information about this topic, see Citrix article CTX107415 at http://support.citrix.com/article/CTX107415. Also, it is possible to disable this behavior. You can prevent the deletion of those printer objects at logoff to enable end users to retain their default printer selection; however, this will have repercussions for the end-user profiles. For more information about retaining Session Printers for the end user, see Citrix article CTX130848 at http://support.citrix.com/article/CTX130848.
