We are looking to configure DHCP HA for our server 2 x 2012 DCs\DHCP servers. We want to implement an active\standby config on each scope. To test, we are thinking of temporarily deactivating the active scope to initiate the fail over to the passive scope (on the secondary DHCP server).
Does anybody have any experience with this and would deactivating the scope initiate the fail over and vice versa to fail back? Also, is there anything to look out for in terms of failing over and failing back?
