Attempting to get a hot standby failover initiated for our place. Windows environment. We have 3 DC's, 3 sites (one DC per site handling DHCP and DNS).
We would like to setup fail-over between them -- Example: When "site 1" DHCP server fails, those scopes are picked up on site 2.
NOTE: We attempted configuring failover in the DHCP options, Hot-Standby mode. Next morning, all the scopes were switched around between the different sites! Shouldn't that only happen with Load Balancing?
Funny, but in all seriousness -- 5 years old? 2012 R2 is still widely used, because 2016 Server tends to break many pieces of software (at least in our environment, and others I witnessed when consulting).
Find one multi-million dollar company using all 2016 servers -- or even 2016 DC's. It is not happening.
