adding a 2008 domain controller to an existing 2003 domain environment
Posted on 2011-03-21
I have a current server 2003 active directory domain setup with 5 DC's across myltiple physical locations, all tied together and replaicating fine
I have a new server I am adding to the domain, it is a server 2008 unit. I went to DC promo the unit to the domain, and I got a message that i had to adprep /forestprep from the 2008 server tools CD on the 2003 before I could promote this unit to AD controller.
What am in for during this process? Do I just go ahead and start doing adprep /forestprep on the other DC's one by one and it is pretty straight forward? What downtime will be expected?
