I'm able to finally access the CIFS volumes I have. The only problem is
that the connection to them remains persistant and even logging off and
back on does not clear the connection. It takes a full reboot to do
this, but then it still seems to cache the address in such a way that
was described by our CIO as "clunky".

The testing I was doing was by typing the UNC path in the run dialog and
logging in when prompted. Any suggestions? Thanks-
