Currently sdudying for 70-640 and have a question to which i can't find an answer on google, not one that is clear to me anyway.
I have 10 DC's. 5 are writeable 2008 servers and 5 are RODC 2008 servers. All are domian controllers.
The forest and domain run at 2008. If I add a RODC 2008R2 domain controller do I need to run either domain prep or forest prep?
