Terminal Server Access Windows 2003

I have two server I installed TS on a server that is not a domain controller, is a member server with Windows 2003 Standart Edition, I have created the users in the other server that is the DC and I need to include this users to the local user group remote desktop on the member server. I can not found the path to find in this member server that is part of the domain the built-in and local groups, I went to Computer Managment and does not appear any option to do that. How can I have access to the built-in local group on the member server? Also I tried to install this snap-in from mmc and does not appear.
