Hi, This is my first post here.
I want to add one 2008R2DC to current domain.
Here is current domain servers
Server1 (DC) – 2008Std
Server2 (DC) – 2008Std
Server3 (DC) – 2008Std
Server4 – RODC (site 2)
Domain and Forest functional level are both windows2003. Should I need to run forestprep, and domainprep again before I install 2008R2 DC?
