IPCONFIG /ALL shows multiple gateways under one interface?

    I've got a problem. I have two NIC's on a Windows 2003 server but the second
    one is disabled. If I look at the TCP/IP settings under the GUI, it shows
    the correct gateway. This applies under the GUI where you can add multiple
    gateways as well. However, when I run ipconfig /all it lists two gateways
    under the same interface! Now, if I change the gateway under the GUI to
    something else and then back to the correct gateway, it appears correctly
    when I run ipconfig /all. However after rebooting, the two gateways once
    again return when I run ipconfig /all!

    The invalid gateway that keeps showing up is an old router from our recently
    updated infrastructure. The reaon why there are two NIC's on this server so
    we can add a SAN volume that’s on a different subnet. Is this some sort of
    corruption? This is one out of four terminal servers. The others don’t have
    this problem.

    Thanks in advance for your help.

  2. Plug the disabled nic into a (separate) hub or switch so that you can enable
    it. Go into the TCP/IP settings of that nic and remove any leftover
    configuration,...apply the changes,...then set the Nic to use DHCP,...apply
    the changes,...then disable it again and unplug it from the switch/hub and
    get rid of the switch/hub.

    Then,...assuming there are no static routes in the OS's routing
    table,...from a command prompt type:

    "c:\> route /f"

    This clears the routing table.
    Reboot,...the table will rebuild accoriding to the Nic(s) configuration.
    Recreate any legitament static routes in the table if there were any.
