The backup DC would just see that replication failed for 15 minutes, then got re-established. Of course the copies are out of sync, as they would be during any failure of replication (such as network outage, etc). I don't see this as too big of an issue. Unless I am completely misunderstanding how AD replication handles temporary outages. > Don’t do it.
