I have a Windows 2003 server which is providing DHCP addresses to client machines. I have just installed a backup circuit from a different ISP. So now I have 2 different ISPs coming into my location. Because of certain equipment and my setup I have need to now point everyone to a new gateway. However if the primary router fails the users will no longer be able to browse the internet because their gateway will be pointing to the new router.
I would like to add an additional gateway in my DHCP server settings so that if the primary route goes down they will be able to go to the other gateway. Is this possible with Windows 2003? Can you have 2 gateways in a DHCP scope? If the first gateway does not get them out to the internet will it automatically fail over to the 2nd gateway in the scope?
