user profiles in terminal session

Hi
Need to know how to use a certain profile in windows 2000 terminal session, and another for the Local workstation.
1 Server 20 workstations.
1. App on certain everyone will use.
1. certain profile when logged into workstation.
breakdown. Really would like to limit the users on the terminal session, and I created a OU and edited the group policy. and sent the users to that policy. But when on workstation they get the same policy as terminal session>? Hope I satated that correctly
