Remote Desktop Users group problem

[pkirill]

I have a Windows 2003 server that is a dedicated Terminal Services/Remote Desktop machine. It is a member of our domain, but not a controller (or PDC). The problem I have is that our remote desktop server does not recognize the Remote Desktop Users group from the PDC or domain level. When I open the TS Configuration, right click on the connection, select Properties and then the Permissions tab, I cannot add the domain level RD Users group. All I can add is the local Remote Desktop Users Group. Which means that whenever I need to give someone Remote Desktop access, I have to do it on the Remote Desktop server. I cannot just add them to the RD users group from their account settings.

Anyone have any ideas what I may have done wrong?

Thanks in advance!
