I have a Server 2012 R2 Essentials server, which is the PDC in the domain. I also have another 2012 R2 server acting as a domain controller for times when the primary is down.
I have setup DHCP on the secondary server as a hot standby. Both servers are communicating fine, and I can see changes at one DHCP server reflected in the other.
From time to time though, the DHCP server on the Essentials server shuts down, and I see this in the system log:
The DHCP/BINL service on this Small Business Server has encountered another
server on this network with IP Address A.B.C.D, belonging to the
domain: .
The IP listed is the server acting as a hot standby. . is not the name of the domain though.
What is causing the DHCP service on the Essentials server to shutdown, and how do I correct it? Perhaps I mis-configured the fail over somehow?
