I have seen some answers to this question on here for this question but I have not seen anyone explicitly state what I am asking so here goes.
We currently have 2 Windows 2003 domain controllers. Functional level for AD is 2003 Native. We have created a VM with Windows 2008 R2 on it and want it to be an additional domain controller in our Windows 2003 AD environment.
basically we want to add a 2008 server in ad a Domain controller but still keep the functional level at 2003 until we are ready upgrade the domain to 2008. we want the 2008 domain controller to act as a 2003 domain controller until we are given the go ahead to upgrade the domain to 2008.
I understand that you will need to run adprep /forestprep and adprep/domainprep
are these commands run on the existing 2003 domain controllers? If so then from what I have read you need to use the adprep32. Will these commands try to upgrade the domain functional level to 2008?
I'm weary about adding this server as a domain controller because at this time we DO NOT want to upgrade our domain functional level (or active directory) to 2008, we just want to use the 2008 server as a 2003 domain controller.
on a separate note we are running Exchange 2007 in our environment. will this in any way effect Exchange at all? will anything need to be done on the Exchange server at all?
My books on these subjects are back ordered :) any help appreciated!
