I have a new DC on 2003R2 that I am building to replace existing 2003 DC. I am at the stage of setting up DNS. I want to build the DNS on the new box from scratch instead of pulling over the old existing one. Since I can't create a zone on the new DC with the same Zone name of "OurDomain" that is currently running on the dying DC, I have some questions.
Does the zone have to be the same name as our Domain? Is there anything I should be aware of by introducing a new DNS zone name? Can I have both running temporarily until finished transfering fsmo roles to the new box?
