We have two buildings connected with a fiber cable. These building work on one flat network, unfortunately. The Windows Server 2008 DHCP server is in the first building. We are trying to provide DHCP to the second building if the first building goes off-line.
I have implemented another Windows Server 2008 DHCP server in the second building and it is working ok. At this point users get IPs at random from either server.
Is there a better way to do this on a flat network?
