I know you say that other versions of windows can access the server, but
Windows integration supposedly does not work through firewalls, and
definitely not through proxy servers. I'm a little fuzzy on the details,
but www.isaserver.org or support.microsoft.com should have additional info
on this. Possibly this is the problem?
