I have zone alarm pro installed as my firewall and it has been
repeatedly blocking netbios requests on port 139 from an IP address
which i know to be a computer on my network.

I cannot think of anything on that computer to be executing these
requests other than a virus. I have done a virus scan with norton and
nothing was found!

A virus could exploit port 139 but that's not necessarily a
sign of one- it's used for file sharing even if you're not
actively requesting one from across the lan you may have
traffic there.
