I am on a two DC domain. DC1 is a 2003R2 and DC2 is a 2008R2. I've inherited most of this stuff so what would be the best way to setup an automatically synchronized copy of my USERs data and DEPARTMENT data? DFS FRS?? Not sure about either of these and what would be the best practice.
I've got a good backup system, I just want that extra measure of backup assurance.
