The host machine doesn't matter. All jCIFS needs is 2 sockets. One for
the NetBIOS name service and the other for SMB transport (but you aren't
getting past name service).

Doesn't matter either.

What could matter is the machine jCIFS is trying to connect _to_. From
the traces it looks like it's not even trying to broadcast for that name
or query WINS. Is this trace with the default resolve order? If DNS is
being tried first the netbios name is going to fail.

I think the position I must take here is that the name service code in
general is not predictable. I am not going to loose clock cycles trying
to decipher this if I know I should rewrite it anyway. Next week I will
start to do that. Having jCIFS try the *SMBSERVER name rather than do
the Node Status first (which is what is failing) should do the trick
for you.

Don't worry, my dad's a TV repair man -- he's got a mean set a tools.
