Hi

My suggestion would be to return the permissions on the GPO to the defaults
so that it Authenticated Users have read and apply. Next enable user
environment debug logging at the verbose level, reboot the server and log on
as the administrator, then harvest the logs ...

221833 How to enable user environment debug logging in retail builds of
Windows
http://support.microsoft.com/?id=221833

These logs usually show you what's applying from where, what's not and why.
You'll typically want the log to reflect one reboot and one logon to avoid
confusion so if you need to make a couple of attempts, just delete or rename
the existing log so that it start from scratch on the next reboot.
