Cannot Connect to Terminal Services Server

I just installed Terminal Services on a 2003 server and cannot RDP to machine. I was able to RDP before installing TS. I have verified users are in the local RDU group and have correct permissions. We are using Active Directory. This IS NOT a DC.
Here is the message I am getting:
"To log on to this remote computer, You must have Terminal Server User Access permissions on this computer. By default, members of the Remote Desktop users group have these permissions. If you are not a member of the RDU group, or another group that has these permissions, or if the RDU group does not have these permissions , you must be granted permission manually"

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Verify that your domain terminal server access group (RDP users) is part of the local Remote Desktop Users group on the terminal server.

We have already verified this.

any other ideas?
You should also make sure the users have the "Logon Locally" and "Interactive Logon" rights.  Check "Local Security Policy" under Administrative Tools to make sure the apropriate gourps (Users, Administrators, Remote Desktop Users) have been granted those rights and that they have not been explicty denied in Do Not Allow Local/Interactive Logon
