I have two file servers running server 2012 R2, Server1 and Server2. They are both configured as AD, DHCP, DNS servers. Server2 hold the FSMO records. DFSR is deployed.
I have DHCP configured for failover if either server should go down for some reason. The Options replicate from Server2 to Server1, but the leases and Reservations do not seem to update, and I cannot add a reservation to server1.
When first set up, the list of leases and reservations seemed to update from either server.
The mode is Hot standby.
What are the best practices for DHCP failover? There are up to 50 users connected to the network
Obviously this will not function as a hot standby because if Server2 failed, Server1 would not have the reservations necessary. Creating reservations is necessary to accommodate the network scanner that directs scans to a specific IP address.
