I have read bits and pieces and wanted to make SURE this is valid.
I have 3x 2003 domain controllers in different sites. I want to add a 2008 server as a 4th DC to the forest and 2nd DC to a site. This server wont hold any FSMO roles but simply act as a DC.
I will install DNS on the DC as a safeguard if the primary fails and adjust the DHCP info. But do I do any thing more than simply add it to the domain and promote it?
