The resource kit has a program called IFMEMBER , which
you can use in your login script logic. IFMEMBER works
by checking for membership in a group and returning an ERRORLEVEL hence you'll have a bunch of IF THENS. Code segment
if not errorlevel 1 goto hrgrp
net use u: \\server1\itsshare$
if not errorlevel 1 goto secgrp
net use u: \\server1\secshare$
Unfortunately, I believe ifmember only works for NT workstations.
