[jcifs] Re: problem if Win2K laptop is not connected to the network

[Michael B. Allen]

I don't know Josef. Didn't we go over this before? It doesn't look like 
this is jcifs more than just underlying networking issues. You're 
getting NoRouteToHostException, NodeStatusRequests going unanswered, and 
Connection refused all in one trace. It seems like some network services 
are just off maybe? I think you can get netmon working if you specify 
the loopback device. You might also mess with the laddr, baddr, hostname 
properties etc. Try using an IP. These are all things that would 
eliminate intermediate steps that might be failing in a loopback env.
