We have stood up a pair of Windows 2012 DHCP servers and configured DHCP failover (in Load Balancing mode) as per the Microsoft Technet article. The two servers are on the same subnet, and time is in sync between them. Almost immediately after
configuring scopes to failover, one node loses contact with the other, and the alternate node goes to failover mode "Recover".
We have restarted both servers and services. Both DHCP servers show as available. Clicking "Replicate Failover Scopes" completes successfully with no errors, and the only two warnings in the Event Log are about credentials for Dynamic DNS updates and a dynamic IPv6 address (which we don't use at all.)
How come they can replicate, but have "lost contact"; and how do we get the one out of "Recover" mode?
