Yes. From either box.

No. From neither box.
When I attempt a ping from either box to the other,
both sets of lights on the switch blink, suggesting
that data is going through the switch, both NICs and
both cables. The lights on the switch correctly show
100Mb/sec full-duplex connections from both machines.
I have already changed the NIC on the gateway machine
in an attempt to solve this. The desktop machine has
a built in NIC and is only a few months old.
Everything worked fine until about a week ago.
