I have a Small Business Server 2008 domain, and wish to add an additional domain controller at a branch office. I currently have Server 2008 R2 STD installed at the branch office with a Site to Site VPN connection, but have not been able to find any info except I will have to run AD Prep on the SBS 2008 server, and dcpromo on the R2 server in order for it to become a domain controller. Has anyone done this to a SBS 2008 server yet? I'm just very cautious because I cannot afford to have much down time.
Thanks In advance!
