I've heard of lots of problems with machines using cross-over
cables. Can you connect the machines through a switch, and ensure
that they are hard-wired to 100Base-TX full duplex at both ends, as
opposed to auto-negotiating?

I've also heard of lots of problems with some machines when the
cable is too short, at least in certain combinations. Try
successively longer lengths of cable, at least up to 20-30m.
