The "local device name is already in use" message is a bug in the
Windows 7 Explorer Shell.   The only part that matters is
\\afs\cs.uwm.edu\ is not accessible.   When the share is not accessible
the Explorer attempts to reconnect the device but when that fails to
make it difference the Explorer forgets to restore the original error.

Port 7005/udp is blocked by a firewall somewhere.   Perhaps all of the
AFS ports are blocked.

Its there because someone established a drive mapping to it.

On what "Network"?  "OpenAFS Network" or "Microsoft Windows Network".
What is the actual output from NET USE?

The problem isn't in NIM or OpenAFS.  Reinstalling is not going to make
a difference.
