How do I sync two seperate subnets two seperate DHCP servers in case one DHCP server goest down?

Windows 2003 Server... I have two subnets on a vLan.  Subnet one is 192.168.0.1 and Subnet two is 192.168.11.1.  One DHCP server currently hands out IP's.  This is a problem when one computer goes from one subnet to the next.  My solution is to add a second DHCOP server.  Have one DHCP server on 0.1 and one DNCP server on 11.1.  This will work out fine and seems like a good solution.  My question is how can I sync these two DHCP servers so if one goes down the other can take over for both subnets as it is doing now.Start Free Trial
