Hi Charlie,

I don't really want to mention the program, or the port, as it might
give away info on how to compromise my system. Suffice it to say that
on computer PC#1 (XP Home SP2) I run the sever and then do netstat
-ano and I see the server listening to the port. When I run it on PC#2
(Also XP Home SP2), it starts normally, but does not show up as
listening to the port.

Note that this server uses localhost, so there's no external network
connection involved. It basically looks at 127.0.0.1:<port X>.

What windows XP system files control the ports? Does Winsock do more
than just dial-up? I'm thinking I can copy a few system files from
PC#1 to PC#2 if something's corrupted.

M.
