2012 Failover clustering

Trying to understand this Failover clustering, since when I tried to apply it to the 2 2012 DC's I have and I had AD on both it would not let me, as it failed the test with the second server having AD installed. I'm guessing this is not the way it's supposed to be used? I read about the second server be read only, but not understanding this.

I was wanting to have the second server to have an identical configuration as the primary for failover.

Active Directory domain controllers should not be in a failover cluster. ADDS is inherently multimaster and resilient so clustering is not required.

Cliff, so you wouldn't have a secondary AD server for failover?
Cliff GaliherCommented:
You can have additional domain controllers. But they don't need to be part of a cluster. That's why I said they are multimaster. They all run, all replicate data amongst themselves, and all can handle normal duties in case one of them goes down. active Directory has supported this since 2000 when it was released without failover clustering being required.
