I have a domain with one DC, and I want to join a 2nd DC to this existing domain.
The forest and the domain functional level is Windows Server 2003, the ser is Windows Server 2003 R2 Standard Edition Service Pack 2.
I had another DC which I had to substitute the server a few months ago, the server I want to promote to a 2nd DC is a Windows Server 2008 R2 Enterprise 64 bits Service Pack 1, this is a member server from my domain.
What I need to do to promote this member server to a DC in an existing domain??
It's necessary run the addprep and/or the forestprep before run dcpromo??
If you could tell me step by step what's necessary and in which servers, I would apprecciate.
