I am trying to access a NetWare 6.5 server w/ SP6 over a SonicWALL VPN from
a Windows XP Pro machine using CIFS. Everytime I try I get this error

\\\Shared is not accessible. You might not have permission to use
this network resource. The network name cannot be found.

This despite the fact that I can PING the server and can access it via FTP
(which is also running) and via NetWare Remote Manager.

Suggestions? Thoughts? Ideas?
