What does it happen when you ping an external address with computer 2,
both IP and Hostname, say www."someplace".com
(http://www.hcidata.info/host2ip.cgi may help you to do this)? Would you
observe the same latency discrepancies?

Why hesitate? It would be nice to check the behavior of this "ancient"
computer regarding pings.

Wouldn't you have a spare lan board to test with the faulty PC?
