  • New SBS2008 server loses gateway

    Everytime I reboot my SBS2008 server it comes back up with no gateway. I've rerun the connect to the Internet wizard and it sees my gateway, so I don't understand why it's not holding it on reboot? After the wizard runs it still has the gateway.

    I've done some searching but I haven't found anyone with this issue.

    Luckily it's not in production yet, but will be soon.

    Any sugestions would be greatly appreciated.

    I found the answer here, just tried it and it worked.

    1. Open the registry with regedit.exe
    2. Go to the path: HKLM/System/CurrentControlSet/Services/Tcpip/Parameters/Interfaces/
    3. Here you'll need to select the CLSID of your networkadapter where you change the settings. You'll probably recognize it by looking at the value IPAddress that will have the IP of this adapter.
    4. Open the value "DefaultGateway" by doubleclicking it. You will see a list of all the gateways that disappeared! (maybe in your case it will be only one, in my case there were due to lots of testing several addresses) Very likely, the first line will be empty. I'm not sure, how this little flaw can make such a big problem. However, if you manually remove this first empty line, click OK and reboot your system everything should be working fine again.

        Can also confirm that the registry fix works

          But before yougo delving in the registry, did you try the "Fix My Network Wizard" ?
