I would hazard a guess that you have one or both NICs set to 
auto-negotiate, combined with a 3COM switch that is fscked as far as 
auto-negotiation goes...

No excuse, on a stable fixed network, not to hard-code the speed / 
duplex...  Unless, like my *^&^&^*( Intel Pro/100+ you can only get 100 
half duplex under Linux...

Grrrrr
