Most likely, your cabling, duplex configuraion, nic, switch are
misconfigured and a high traffic ap like rdesktop is pushing them over
the edge.  I'd check the duplex settings on each end and try another
cable first.  Then try a different nic and switch if possible.  It's
possible the problem is a driver bug, but it's more likely you've for
some sort of physical network problem.
