A few things ..

First, both speed & duplex are set manualyl at both ends. In fact, I did
this more than a year ago as a recommendation to solve this particular
problem we're discussing now. In other words, the problem existed before
I manually set speed/duplex, and afterwards.

Second, the problem doesn't ever sort itself out. If I don't reboot the
server, the problem continues indefinitely. 

Last, here is the output of netstat and ifconfig:

Note: The parts marked with 'x' are indicating my internet IP address,
which I am futilely trying to mask. 

Thanks.
