I'm thinking of adding a 2nd domain controller to our network (2003 domain), and i have a few questions. Our primary dc has windows server 2003 on it and the the server i was thinking of promoting to a dc has windows server 2008. My research has lead me to the 2008 server will reduce functionality to a 2003 level. Now does this effect software on the 2008 server? We use SQL server 2008 and IIS 7.0. Would promoting this server cause a conflict with this software?
My second question is on the actual promoting of the server. Now i know all i have to do is type in "dc promo" and follow the wizard, and AD will copy itself to the 2008 server. Our primary dc also does internal DNS for our network. Will these settings be copied over also, or does DNS need to be manually setup on the 2008 server?
Any help/guidance would be appreciated
