well, you'l tell us?

e.g.: what's the WAN network number? how's that configured? are they 
physically connected via the same switch/or even worse a hub?

what are the other 29 PCs doing? have you lokked at each and every 
single one of them? have you looked at each and every end of Network 
cable in your net (is there a "hidden gateway" instaled by some clueless 
/ reckless user?

lots of possibilities.
