  • One computer in the LAN acts as a Black Sheep...

    Dont know why, but it refuses to get an IP by DHCP.
    It's mac address is writtend down in the router (NETGEAR) and the
    internet and the IP mapping is working fine on the other 2 computers.

    I had a SASSER Crush at that PC. dunno if that has any relation.
    If anyone had some experiance with such problems please help
    me solving mine...


    Good Day.

    What OS? Did it ever have a dynamic IP, does it work with a static one?

      WinXP Sp-2, Other pc'z have auto IP when the router..

      WinXP Sp-2, Other pc'z have auto IP when the router actualy maps the IP for each PC by the mac address of the network card.

      It works without the mapping also...
      So let's say I can give a pc a static IP and it will work k,
      but this specific pc wont work properly.

      I can access it thru the lan, in the workgroup, and transfer files
      from and to this pc, but no Internet connection...

      I just cant figure it out.

      Thank you and good day.

        So now you say it does work on the LAN? If you want us to help you'll need to tell us all about your settings, otherwise it'll be a guesswork, and that's something I'd like to avoid.

            What IP are you trying to give it (assuming a class see, something like xxx.xxx.xxx.12 is an example).

            How many computers do you currently have set up like this?

            What settings are running on the router (straigh DHCP, or DHCP via MAC, etc).

            What NIC (Network Interface card) are you using?

            Are you using a server to firewall, that requires the router to verify you via MAC address or something like that?

            If you change a working computer to a Static IP, can it still access the internet as well as the Workgroup LAN??

            B.
