I have several Windows 2003 servers running as terminal servers. As near as I can determine, all are configured the same way. All have been running successfully for at least a couple of months (some longer). Today, we started getting the message:
“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 Remote Desktop Users Group or another group that has these permissions, or if the Remote Desktop User group does not have these permissions, you must be granted these permissions manually.”
I’ve been all over this server, comparing to two others. “Allow logon through Terminal Services” has everyone listed. The Remote Desktop Users group is populated as well. I haven’t found anything at Microsoft that covers this. Logon fails with both RDP from Windows XP workstation and the older mstsc client from Windows 2000 workstation.
Remote Desktop Users group does have Domain Users. RDP-tcp properties under the security tab shows that Remote Desktop Users have permissions.
The server is not a domain controller, nor are we running Active Directory.
Is there a feature that may have been turned on that would cause this?
