Terminal server 2003 local drive access not available non ..

Archived from groups: microsoft.public.windowsnt.terminalserver.client (More info?)

Performed an upgrade from terminal server 2000 to 2003. This is a
member server of a domain. Added the appropriate users to the local
Remote Desktop Users group to allow them login. The users can login,
but to not see local redirected drives even if checking the option in
the RDP client. However, if a user is a member of the terminal
server's local administrator's group, they do see the drives. I
obviously can't leave everyone a member of the local computer's admin
group. I've done a new install of a 2003 terminal server before and
didn't have this issue. Is there a security setting that I'm missing
somwhere? Permission compatibility is set to Relaxed Security. Any
help is much appreciated.
