I've had a network with 2 XP SP2 computers for a while now, and everything
is great, Internet-file sharing all work great.

A friend of mine has a computer in the back room, and he's never upgraded
from Win98, the first edition. I had an extra network card, a NetGear FA311,
and we installed it and connected his machine to the router.



You need to check basic connectivity first and describe the ip
addressing scheme you are using. Is the router issuing private ip
addresses to all the computers? Can PC1 ping (and be pinged by) PC2
and the router using ip numbers?
Can you ping 4.2.2.1 and get a response?

Along with this information post a routing table for the 98box and one
of the xp boxes which work correctly for comparison.
To get the routing table into a text file type
"route print temp.txt" and the paste the contents of temp.txt here
