You will copy the Horizon Extras Bundle zip file to a local folder on the Domain Controller and extract it there. That minimizes Windows file security checks that, in some environments, can prevent copying files from a network share to the domain repository.

If prompted for Replace or Skip files, select Replace the files in the destination.

If your Windows Server uses a language other than English, you would copy the ADML files from the appropriate language folder of the extracted zip file to the corresponding language folder in the domain repository.

In a production environment you would normally have multiple domain controllers and would need to wait for SYSVOL replication to complete (typically 5-15 minutes) before the template files are available on other domain controllers.

You will notice that there are multiple Omnissa Horizon administrative templates available in the Group Policy Editor. Feel free to explore the settings and configurations that are available.

Although in this lab you only configured computer settings, you can also apply user configuration in the GPO. When setting user level GPO settings, it is often useful to use GPO loopback processing mode. This is a Group Policy feature that applies user-side policies based on  the computer a user logs into, rather than the user's own location in Active Directory. For more information, see the Microsoft website.

A GPO can be linked to multiple OUs.
