Glenn-

The user is in the same OU as the other users and from what I've been told the problem exists on other computers. However I have not verified that with this users account am basing that off me requesting she try from one of the other computers.

The GPO is new so there aren't any excluded users, I even tried to add her specifically with no success. As mentioned the RSOP data shows that the Logon GPO has been applied to her user account.

Thanks for the heads up on using the domain in the GPO. This client is fairly small at this time and only has the one server, but this will be good for some other installations that I'll be setting up in the near future.
