I have the task of upgrading our network to Active Directory that currently uses a workgroup. I will be installing 2 new Domain Controllers (Windows server 2003) and want to use Active Directory integrated DNS. My plan is to let the first Server's promotion happen via dcpromo and let it install DNS for itself. After that I want to promote the second server via dcpromo as a second DC in the domain. I want to install DNS on the second DC as well for redundancy but am unsure as to what type of zones to create. Will AD integrated primary zones on the second DC create new zones, making it neccessary for secondary zones instead? Also after this is done how should the DNS IP settings be for the DC's.
