Yachnin,
This is a well known problem here, but can have many causes. One of the most
common would be a misconfigured or overlooked personal firewall, or other
security component. There are several other possibilities too, and any might be
the cause of your problem. Read this article with an open mind.

Look at provide "browstat status", "ipconfig /all", "net config server", and
"net config workstation", from each XP computer, and we can probably diagnose
the problem. Read this article, and linked articles, and follow instructions
precisely (download browstat!):

Thanks for your reply. I've added the diagnostics you requested from two of
the XP computers. One of them, Main, is the problematic machine. The
problem persists regardless of which of the other machines is present. I've
tried shutting down firewall and security software to see if that helps, but
no change. Also, I noticied that there have been problems with NVIDIA nForce
products. I *think* that I have a nForce2, which I *think* predates the
introduction of the firewall. I'm not sure, though. Is there a good way of
checking this?
