Public Nic stops responding - no evidence of why

Discussion in 'Windows Networking' started by MajorWorkload, Sep 14, 2006.

  1. hi
    I have a windows 2003 server with 2 GB network cards
    One is on the public network, and on on the private network
    Same config as another window2003 server which works
    Except on the new one,
    every couple days, ,mostly in the middle of the night, the public card stops
    responding. it reports that its connected, and there is nothing in the event
    log.
    I repair the public nic, and it starts working right away.
    Anyone have any ideas what could be causing this, or a fix?
    thanks a bunch
