Interesting... I'm not sure if it's related but I'm having
other non-Python problems with Win2K and Samba.
I have a network drive mapped to a directory on a linux box
running Samba and when booting up the Win2K box it _always_
says it can't find the network drive, but if I go into
Windows Explorer or something and try and open that network
drive it works perfectly and everything after that can
access it fine.
So it looks like some of the ways Win2K tries to login to Samba
don't work, but others do...
