DNS and AD DS
Applies To: Windows Server 2016, Windows Server 2012 R2, Windows Server 2012
Active Directory Domain Services (AD DS) uses Domain Name System (DNS) name resolution services to make it possible for clients to locate domain controllers and for the domain controllers that host the directory service to communicate with each other.
AD DS enables easy integration of the Active Directory namespace into an existing DNS namespace. Features such as Active Directory-integrated DNS zones make it easier for you to deploy DNS by eliminating the need to set up secondary zones, and then configure zone transfers.
For information about how DNS supports AD DS, see the section DNS Support for Active Directory Technical Reference.
If you implement a disjoint namespace in which the AD DS domain name differs from the primary DNS suffix that clients use, AD DS integration with DNS is more complex. For more information, see Disjoint Namespace.
