<br><br>I have two machines (92A & 92B) that are conencted via a 3ft patch cable and dedicated NICs, so I would not expect there to be a connection failure between the two. It seems I had one. I had a similar error on another pair of machines a few weeks ago. Is there anything obvious from these two abbreviated logs, or does it just look like they lost contact with eachother? Something happened at 15:23:58.
