Hoary upgrade: no network connection

[Carl Karsten]

Next guess - your problem has nothing to do with the upgrade, but 
another box on the LAN has the same IP, or maybe MAC.

You said you can't ping the gateway during the "blackout" - can you ping 
it now? (just to be sure your admin hasn't done something dumb.)

During the "blackout", can you ping localhost?

If no, then stop, else

During the "blackout", can you ping another box that is up, and can it 
ping you?

If No to either, is it posaible to isolate the 2 machines from the rest 
of the LAN, like with a crossover cable, unplug everything else from the 
hub/switch or plug the 2 into a spare hub? (what, everyone doesn't carry 
around a hub with them?)
