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"
