Don't be so sure... I got the "Request timed out" when I tried pinging a
linux machine with a 65510 byte packet, but, when i triedto ping the
machine again with just "ping machine.ip.address", it was, SURE ENOUGH,
down.....
I tried this numerous times, and they ll went down.. Yes, I am using the
"latest" win95, with the service pack installed and everything....
just my 2 cents
