The UNC Path Redirection ADMX template file, called uncRedirection.admx, contains settings that enable you to control whether a UNC Path is opened on the client (agent-to-client redirection) or in a remote desktop or published application (client-to-agent redirection).

To apply the UNC Path Redirection group policy settings to your remote desktops and published applications, add the ADMX template file to GPOs on your Active Directory server. For rules regarding UNC Path clicked in a remote desktop or published application, the GPOs must be linked to the OU that contains your virtual desktops and RDS hosts.

You can also apply the group policy settings to a GPO that is linked to the OU that contains your Windows client computers.


  • Verify that the UNC Path Redirection feature is included when you install Horizon Agent. See Installing Horizon Agent with the UNC Path Redirection Feature Enabled.
  • Verify that Active Directory GPOs are created for the UNC Path Redirection group policy settings.
  • Verify that the MMC and the Group Policy Management Editor snap-in are available on your Active Directory server.
