Well, so far the two services you mentioned this happen with require the
clients to be setuid root so that they can bind to a privileged port. Are
rlogin and lpr setuid root on the machine in question?
It is also possible that normal users dont have permission to even run the
clients. Check the permissions of rlogin and lpr. Make sure that:
1) users can execute them
2) they have the setuid bit set ( and are root owned ).
