One of the possible reasons that the administrator is not seeing the printers within his Horizon Desktop session is that printing is disabled in the Horizon Desktop Pool. Printing is a feature that allows users to print from a remote desktop to any local or network printer available on their client device. Printing can be enabled or disabled for each desktop pool by using the VMware Integrated Printing feature.

VMware Integrated Printing is a feature that supports client printer redirection, location-based printing, and persistent print settings. Client printer redirection enables users to print from a remote desktop to any local or network printer available on their client device. Location-based printing enables users to print to network printers that are physically near their client device. Persistent print settings enable users to retain their print settings across sessions.

To enable or disable printing for a desktop pool, the administrator needs to follow these steps:

• In Horizon Console, select Inventory > Desktops.
• Select the desktop pool and click Edit.
• In the Edit Desktop Pool dialog box, select the VMware Integrated Printing tab.
• Select or clear the Enable VMware Integrated Printing check box.
• Click OK.

If printing is disabled for a desktop pool, users will not see any printers within their Horizon Desktop session, even if they have installed the VMware Integrated Printing feature in the Horizon Agent and the Horizon Client. Therefore, to resolve this issue, the administrator needs to enable printing for the desktop pool by selecting the Enable VMware Integrated Printing check box.

The other options are not likely to be the reason that the administrator is not seeing the printers within his Horizon Desktop session:

• Port TCP 9427 is disabled: This port is used by the VMware Integrated Printing feature for communication between the Horizon Agent and the Horizon Client. If this port is disabled, users might experience printing errors or delays, but they should still see the printers within their Horizon Desktop session.
• The VMware Integrated Printing feature is not installed in the Horizon Client: This feature is installed by default in the Horizon Client for Windows, Mac, Linux, Chrome, and HTML Access. If this feature is not installed in the Horizon Client, users might not be able to print from their remote desktops, but they should still see the printers within their Horizon Desktop session.
• Port TCP 32111 is disabled: This port is used by ThinPrint for communication between the Horizon Agent and the ThinPrint Client. ThinPrint is a legacy printing feature that has been replaced by VMware Integrated Printing. If this port is disabled, users might experience printing errors or delays with ThinPrint, but they should still see the printers within their Horizon Desktop session if they use VMware Integrated Printing.

VMware Horizon's Dynamic Environment Manager (DEM) is designed to provide a consistent and personalized desktop experience for users across different sessions and desktops. DEM manages user profiles and policies dynamically, ensuring that user settings, preferences, and application configurations are consistent no matter which desktop a user connects to, thus meeting the requirement for a uniform desktop experience.

Application Profiler is a tool that analyzes the registry and file system locations where the settings for a particular application are stored, and creates a Flex configuration file for use with Dynamic Environment Manager. Application Profiler is installed using VMware Dynamic Environment Manager Enterprise Setup Wizard and explicitly selecting local drive installation1. This option allows you to install Application Profiler on a separate machine from the Dynamic Environment Manager Agent or Management Console. Alternatively, you can install Application Profiler on the same machine as the Dynamic Environment Manager Agent or Management Console, by selecting network share installation1.

VMware Dynamic Environment Manager Agent and the Application Profiler can be installed on the same machine, but it is not recommended. This is because the Dynamic Environment Manager Agent might interfere with the profiling process by applying settings to the application being profiled1. Therefore, it is best to use a clean system for profiling applications.

Application Profiler is not installed automatically when installing VMware Dynamic Environment Manager FlexEngine or Management Console. FlexEngine is the component that applies the user environment settings during logon, logoff, and session reconnect or disconnect events2. Management Console is the component that allows you to configure and manage the user environment settings2. Neither of these components requires Application Profiler to function. Application Profiler is an optional tool that helps you create Flex configuration files for applications that are not included in the predefined settings library1. References:

• VMware Dynamic Environment Manager Overview2
• Using Application Profiler1

To improve the user experience when using Application Profiler from Dynamic Environment Manager to create application-specific user defined settings, the administrator can configure exclusions to filter out unnecessary folders and registry entries. Exclusions are rules that specify which file system or registry locations are not included in the Flex configuration file. Exclusions can reduce the size of the Flex configuration file and the profile archive, and improve the performance of the application profiling and synchronization processes12.

The other options are not valid or effective because:

• Changing the default save path does not affect the size or content of the Flex configuration file or the profile archive. It only changes where the files are stored on the local machine3.
• Using Deepest Registry Path does not reduce the size of the Flex configuration file or the profile archive. It only changes how the registry locations are displayed in the Application Profiler interface4.
• There is no such thing as Cloud Entitlements in Dynamic Environment Manager. The correct term is Global Entitlements, which are used in Cloud Pod Architecture to entitle users to desktops or applications across multiple pods5.

VMware Horizon Cloud on Microsoft Azure is the only deployment solution that meets all the requirements. VMware Horizon Cloud on Microsoft Azure supports Windows 10 Enterprise multi-session desktops, which are a new Remote Desktop Session Host exclusive to Azure Virtual Desktop on Azure1. It also supports App Volumes, which is a real-time application delivery system that enables IT to instantly provision applications to users or desktops. VMware Horizon Cloud on Microsoft Azure supports centralized brokering, which means that the Horizon Cloud Service acts as a single point of entry for end users to access their virtual desktops and applications. VMware Horizon Cloud on Microsoft Azure also supports automatic routing of end-users to the most appropriate virtual workspace, using the Universal Broker feature. Universal Broker is a cloud-based brokering service that provides a unified user experience across multiple Horizon pods and clouds.

VMware vSphere Desktop Edition does not support Windows 10 Enterprise multi-session desktops, as they are only available on Azure Virtual Desktop1. VMware Workspace ONE Unified Endpoint Management does not support App Volumes, as it is a different solution for managing devices and applications. VMware Horizon On-Premises does not support automatic routing of end-users to the most appropriate virtual workspace, as it requires manual configuration of load balancing and global entitlements. References:

To enable debug logging for a single user in VMware Dynamic Environment Manager, the administrator needs to create an empty FlexDebug.txt file in the same folder as the standard log file for this user. This will trigger FlexEngine to switch to debug logging for this particular user1. Debug logging is useful for troubleshooting purposes, as it provides more detailed information about the FlexEngine operations and actions1.

The other options are not correct because:

• Updating the FlexEngine registry to DEBUG will not enable debug logging for a single user, but for all users who log on to the same computer. This option can only be set through Group Policy settings and applies to all users1. Moreover, this option is not recommended, as it can cause performance issues and disk space consumption due to the large size of the log files1.
• Creating an empty FlexDebug.log file in the log folder will not enable debug logging for a single user, as the file name must be exactly FlexDebug.txt. The file extension must be .txt, not .log1.
• Configuring the FlexEngine GPO to DEBUG will not enable debug logging for a single user, but for all users who are affected by the GPO. This option can only be set through Group Policy settings and applies to all users1. Moreover, this option is not recommended, as it can cause performance issues and disk space consumption due to the large size of the log files1.

The reason for the issue is that the administrator may not have added an instant clone domain administrator to VMware Horizon. This is a requirement for creating an automated farm of instant-clone virtual machines using the Add Farm wizard.

An instant clone domain administrator is a user account in Microsoft Active Directory that allows Connection Server to perform certain operations related to instant clones in Active Directory, such as joining instant-clone virtual machines to the domain, creating computer accounts, and deleting computer accounts. The administrator must create and configure this account in Active Directory and then specify the user name and password in VMware Horizon.

To add an instant clone domain administrator to VMware Horizon, the administrator needs to follow these steps:

• In the Horizon Console, select Settings > Domains > Domain Accounts.
• Click Add.
• Enter the domain, user name, and password for the instant clone domain administrator.

After adding the instant clone domain administrator to VMware Horizon, the administrator can proceed with creating an automated farm of instant-clone virtual machines using the Add Farm wizard.

The other options are not the reason for the issue:

• In the Add Farm wizard, the administrator may not have selected Automated Farm as farm type: This option is not relevant to the issue, as the farm type selection is done in a later page of the Add Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which is the first page of the Add Farm wizard.
• The administrator did not prepare a RDSH golden image snapshot: This option is not relevant to the issue, as the RDSH golden image snapshot selection is done in a later page of the Add Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which does not require a RDSH golden image snapshot.
• The administrator did not add the RDSH golden image to the correct domain: This option is not relevant to the issue, as the RDSH golden image domain selection is done in a later page of the Add Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which does not require a RDSH golden image domain.
