Sorry it didn't do the trick. I did notice that when I ping the receive
icon in the system tray lights, but the send doesn't. Looks likes its
getting the pings, but doesn't recognise them and rely. Data flows if a
connection is initiated from the W2k side, but no connection can be
initiated from the linux side. Likewise, broadcasts seem to be dropped.
The packets get here (the rec'd counts increment proportional and in time
with activity), however, win2k is dropping them like [insert silly
hyperbole/simile].
Some details...
Windows 2000 Professional SP2 (Winver -> 5.0 Build 2195 SP2).
Here's the syslog messages -
