Multiple Computer connecting to Server using RDp and printing issue

I have several usersconnecting to a Windows 2000 server using RDP.

I have checked their connection setting to make sure it is connecting their local printers. The problem is their default printer is not changing to their printer. It could be any random printer of any of the users that are logged on at that time.

Any help on making the users default printer theri default while logged into RDP.
