Are the both running portmap ? That's the only think that strikes me
straight off...or maybe DNS. Some stupid commands in 7.1 and 7.2 do DNS
lookups before doing anything. Ping, for instance. Real pisser if you are
trying to work out if you network is dead, or just the name server...

Crap hardware ?

Ok. I think it could just be the software install is haunted.
