That's very odd indeed.  The not defined is almost certainly an option 
negotiation failure, most PXE stacks seem to force one on purpose before 
starting the real transfer.

I hate to suggest this, but could you by any chance have either an 
address conflict on your network or a hardware/cabling failure?  The 
fact that it only affects one box our of a set that is known to work 
well is sticky...
