I'm setting up a Windows Server 2008 R2 RDS environment (with Citrix). Now I want to disable the known folders like library, music, pictures and so on through GPOs. I found an linke with the ID's and I guess the canonical names:http://msdn.microsoft.com/en-us/library/dd378457(v=VS.85).aspx
I entered a few ID's in the policy and linked it to the server (see attached document).
Then I logged in with a new profile (first time login) and the folders are still available (see attached document).
I checked already the registry, and the policy has been applied.
