I'm guessing you did a new install of SQL2k ... if I recall correctly, one
of the default Network Configurations includes NamedPipes as well as TCP/IP
... which in turn will lead to some issues with being able to use TCP/IP.
Try clearing NamedPipes.

This may also be a role/user access issue on the Win3 server.
