When a Windows Server 2012 Remote Desktop Virtualization Host is added to a domain and the default domain policy is applied, the option to select a physical GPU used for Remote FX (within Hyper-V settings) is unavailable.
Even if the option to select a physical GPU in the Hyper-V settings is available, you are unable to add the RemoteFX 3D Adapter to the Virtual Machines provisioned on the host server.
The issue can occur if the Default Domain policy (or any other policy) has removed the “Users” group from the “Allow log on locally” policy.
The RemoteFX feature availability in a Remote Desktop Virtualization host is provided by a system account named 'RDV Graphics Service'. This account is part of the local ‘Users' group on the Remote Desktop Virtualization Host. If the 'Users' group is denied the permission to logon on to the system, the account in turn is also denied permission to log on to the server.

Note: The same steps apply to a Domain Group policy (or any other Group policy) that needs to be added or modified using Group Policy Management Console.
