I suspect the transmit error is unrelated to the network stoppage.
error 82 refers to the NIC detecting a collision after more than 128
bytes of a single packet have been sent. Yes, this is probably be due
to something misbehaving on your network but the driver recovers.
The stock 2.2.12 driver has a number of quite serious problems. One
which comes to mind was a packet counter wraparound thinko which could
cause the receive path to fail after the interface has received 2
gigapackets. I note that you've almost hit that level again....
The answer is to apply the latest service pack :).

I'd expect either one to fix this problem.
