GPO's not being applied after upgrade to 2008 R2
I recently just upgraded my PDC from 2008 to 2008 R2 and after what I thought was a smooth upgrade I have come to find that GPO's are not being applied to anyone (Windows XP or 7, Server 2003, or Server 2008 R2). During the process of upgrading I also upgraded the Domain Functional Level from 2003 to 2008 R2 as this is our only DC and thought this was a logical solution. Now not even the simplest GPO is applied to clients. I have created new GPO's to test and even those don't apply. Did I miss something?
