Windows has 2 default gateways set and the first is 0.0.0.0 which is causing network failures
You may have installed a new Windows 2008 server or Windows 7 workstation with a static IP address but networing outside your localnet fails. After you investigate you find by running “ipconfig” that there is 2 default routes listed. You see first 0.0.0.0 and then you see your real default router IP address below the 0.0.0.0 address.
This is preventing you from accessing the Internet as it believes the first route to the internet is your local IP address and it goes nowhere. You need to get the first route out but if you use “route delete” on the next reboot it will right back and you will be left without Internet access so what do you do?
You need to edit the registery and remove the entry listed in the default route key. To do this go to:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\your interface #\DefaultGateway
You will most likely find if you edit this key 2 IP addresses listed and the one you want being listed as the second IP in the list. Just remove all IP addresses but the real gateway address.
Close and reboot then try to ping out and it should now work.
