>From looking at the code it looks like InetAddress.getLocalHost is
returning null. I don't recall off the top of my head why this occurs
but it has to do with the local system cofiguration. Try:
$ hostname
on both systems and see if you see an inconsistency. I think if it returns
'localhost' or '127.0.0.1' that will cause problems with JCIFS. One way
to hack around this is to add an entry in /etc/hosts.
Search the archives on google like:

etc.
