There = is no routing between the LANs. One is for internet connections and the = other for purely internal traffic. Both the LANs are 100 Mbps switches = (different models). One of the servers is showing ethernet errors on = both interfaces. One interface has more input errors than output, and = the other is reverse. None of the other servers or devices show any = errors ever. It seems a bit strange that two switches would have errors = on one port or that one server would have errors on two different NICs = (different manufacturers) starting at about the same time. The errors = do continue to build up, but very slowly. This server does see quite a = bit of traffic, but its not as much as it used to be when there were no = errors. I am at a loss to explain what is going on or where the problem = might be. Any ideas? Unfortunately these servers are a 3 hour drive = away at 1 AM. It=E2=80=99s considerably longer during the day as I have = to drive through Los Angeles.
