We have a 2003 TS with a 2008 running our AD. I created a OU and moved the 2003 server into the OU. I created a Policy for that OU and choose Group policy Loopback with replace mode. It does not seem to be working on the terminal server in that OU. Ran the GPUpdate and even restricted to no results. I have reviewed the policy and it seems I choose all the settings i was looking for. Any ideas or steps I missed? Or does anyone have a link to a step by step process on locking down the TS?
