It's unlikely that there are physical networking problems (cables,
hubs or NICs). ifconfig show zero errors, and all other applications
work perfectly. The exact same machine worked perfectly in its
previous life as an NT4 server.

That of course doesn't necessarily mean that the problem is with Samba. It
could be the Linux kernel (2.2.19) or the driver for the NIC
(3c905c).

Is it possible with e.g. tcpdump to diagnose this problem? I can
provide detailed info, I just need to know where to look. :-)

Since this is a production machine, I'm not able to toy with it too much.
I'll see what I can do, of course.
