Current AD domain is 2003 servers schema updated using adprep for 2008 R2.
I am running the DCPROMO wizard on WIndows 2008R2 server and get the following listing on the screen where it asks which services to install DNS, Global Catalog:
There are currently no DNS servers registered as authoritative name servers for this domain.
A domain controller running Windows Server 2008 or Windows Server 2008 R2 could not be located in this domain. To install a read-only domain controller, the domain must have a domain controller running Windows Server 2008 or Windows Server 2008 R2.
I do a nslookup from the server for the domain and receive the authoritative response from the current DNS servers.
Checked and the ZOne lists the current DNS servers, I do want to install DNS on this server but am concerned that it is saying there are no authoritative DNS servers, I do not want to destroy the existing DNS.
Any advice greatly apreciatted.
