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.
