For Active Directory Domain Services (AD DS) to function properly, DNS Server must be installed and configured correctly. AD DS registers resource records in Domain Name System (DNS) zones so that DNS clients can locate domain controllers. You must configure DNS clients with the address of a DNS server that can refer to the required zone data. The DNS server must either host the required zones itself or be able to use forwarding or delegations to reach another DNS server that hosts the required zones.
