HERB!!! Thank you SO MUCH for your time and effort. You pointed me in the
right direction, and that was firewall interference. There was a secondary
application running under Norton (2 icons running in the sys tray, I didn't
realize the other one was Norton as well), and I found the firewall settings
and told it to let Computer A (Wendy-zmud8nvrn) in. A ping here, a ping
there and we have communication.

In the meantime, I learned about Cmd prompt files, and that neat little
trick about getting them to write directly to a .txt file, and a whole lot
about communication.

I've been trying to figure this out since last Tuesday, so it is such a
relief to get it solved.
Again, thanks a million for your time and expertise. I couldn't have done it
without you, and I'm saving all your emails to my geeky win2000 archives.

Have a great night!
