This is the same problem that I reported yesterday. What version of windows is your
LMB? For me it works if the LMB is win9x (most likely it doesn't respond to port 445
at all :), but not when it's XP ;(
I even attached the tcpdump log. But I haven't tried accessing port 139, so this is
something to try indeed.
