I have loop back processing working on a 2008 terminal server. When the gpo is applied to authenticated users it works and drives are hidden. I only want to apply to policy to a particular security group. However, when I do this, the part of the policy that hides the drives no longer is applied. I can see this in group policy results and in actuality.
The permissions for the GPO are the same for Authenticated users and the Security group I created.
