Hi everyone out there,
I have been having problems getting a new server 2012 to work properly in my forest.
My forest is mainly controlled by a Windows 2008 R2, under 2003 compatibility. Just wanted to join a new Server 2013 but looks like the AD DBs aren't fully compatible. Does that mean that I have to promote the 2012 to become the main Domain Controller and everything older should be right underneath. Any best practices from any one out there with similar problems?
