Windows 2012 Server -- "Active Directory domains" ?

What are some good "Windows 2012 Server
Active Directory domains" step-by-step
setup websites since it looks like in the
NEW Active Directory domains, the concept
of primary and secondary domain controller
relationships no longer applies ?
Current Setup
      ** two locations using site-to-site VPN
      ** old 2003 "Domain Controllers"
      ** want to move to "Windows 2012 Server"

   1. primary domain controller (PDC: at site #1
   2. backup domain controller (BDC: at site #2
   3. replication between controllers
       ** site #1 client DNS
            ** primary DNS =
            ** secondary DNS =
       ** site #2 client DNS
            ** primary DNS =
            ** secondary DNS =
   4. if either controller goes down, users can
      still login/etc using the other controller

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The concept of a PDC and a BDC went away with 2000. NT4 was the last server version of windows that had such a concept. So this isn't new. Any study guide for a 2000 - 2012 R2 administrator MCSA exam will cover the basic concepts.

I do recommend books over websites as reputable publishers screen content and authors, unlike "random blog x from guy in his basement."

But if you really want free, the Microsoft Virtual Academy is a good place. Many modules are available, including good ones on 2012 and active directory.
