    Server’s LAN adapter hangs on long pings

    Locked

    by mike_m ·

    NT4 SP6 Server
    Mixed clients
    Had occasional network hang ups
    Found out that I can trigger the hangup sending long pings on the network (-l 50000) to a remote PC that is limited to 10Mhz (but it normally works resolved by the router).
    When I pingthis client (w98SE) and have a request time-out, server’s LAN board hangs up,
    no connection is seen anymore, and have to restart it to make it operational again.
    Default gateway goes to Internet remote share.
    Must at least avoid server’s hang up,then will make network consistent to 100Mhz, but can’t accept an unknown hang up situation.
    Something must be wrong with settings but can’ t understand what. Apart from this all semms to work correctly and relyably, exept primary WINS (see my previous question). Secondary WINS is OK.
    Any hint ?

      After some test add the following:
      – router is obviously a switcher
      – Default gateway has nothing to do with the problem: Nothing changes with gateway to itself.
      – Tracert gives no information: when the problem arises it looks just as a dead adapter board. Nothing goes in and nothing goes out. Ping to itself is OK.
      – Logoff and logon don’t restore operation.

      Hi Mike_M,
      I have seen this with buggy NIC drivers and or NICs that are faulty. Particularly Netgear FA311 and some Realtek chipset based NICs. Replace the NIC (use a 3Com or Intel NIC), re-load the drivers and see how you go.

        Ok, it worked. It was a Realtek chipset. also had to remove and uninstal NetBios to have everything ok. Thank you. I didn’t think it could be adapter’s bug.
