Resolved: W2k -> Solaris: Cannot connect to port 139

[Michael Kolmodin]

Thanks for the hints. The problem seems to be that NT in some
situations routes packets to hosts on the same network via
the default router. In my case, this is the ISP's router which
blocks port 139 (and only that one, BTW). The routing is not stable,
sometimes the packets goes direct. This explains the random
behaviour and that no other service is affected.

I know it sounds silly, but below you will find the logs describing
how my stupid NT client (address 213.113.120.125) routes packets
to the host mumin/213.113.120.70 via the default router. Note that
according to the output from the "route" command this should not
happen. But it does, at least according to "traceroute".

Any idea where this kind of topics are best discussed out there?
I think I understand the problem, but have no solution on hand
right now. But I see some light in the tunnel... And I'm happy
to inform all of you that my suspicions regarding samba where
totally wrong :-)
