I have created an AD group called RDSusers and place the users that I want to give access to our Windows Server 2008 R2 Remote Desktop Server. On the RDS server I added the AD Group RDSusers to the local group Remote Desktop Users. The administrator works just fine. But when a non administrator attempts to login they get the "The connection was denied because the user account is not authorized for remote login." If I go in and manually add a specific non admin AD account to the same local Remote Desktop Users group they can get in. If I remove them from the group they cannot. But that user is a member of the RDSusers group which is a member of Remote Desktop Users group. Why is the group inside a group not working????
