    Hi guys. I have a Window Vista PC that keeps loosing it's gateway. It looses this randomly or on a reboot.
    I'm using static IP (Not DHCP). It keeps everything else Subnet, DNS and IP address just not the gateway.
    Any idea guys.

    Just to confirm, you're saying that you can do an ipconfig /all and see the proper static IP configuration, and then later you do another and it is exactly the same except the Default Gateway is blank?

    Is it still correct in the TCP/IP Properties, or do you have to assign it again there?

    Terry in TCP/IP properties the gateway goes blank. I haven't tried by checking ipconfig.
    I can only assume it's gone from there also as the PC looses all connection.

    I have never heard of that happening, have no idea what could cause it, and the only thing I can offer in the way of hope are the following repairs.

    (From a JohnWill post)

    TCP/IP stack repair options for use with Vista or 7.

    Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

    Reboot the machine.

    Gave that a try Terry but it failed with a message saying 'Needs elevation'
    I've tried enabling DHCP and it keeps the gateway. Unfortunately I need to use a static IP on this PC so no good long term.

    No. I wrongfully thought being signed on as an admin was enough. Redid it letter by letter and it did the resets just fine. All done remotely so won't know the result for a couple of days. Will report then.
    Sorry for being a twat.

    Doubt the repairs will help, but as I said I really am baffled by this one.

    Just an update. Ain't exactly cured the problem. I have got rid of it for now by just enabling DHCP. I'll revisit when I can.
    For now thanks guys for you time and efforts.
