It is possible to configure DNS servers that are also domain controllers to store the contents of the DNS database in the Active Directory which will then be replicated to all domain controllers in the domain.

  3. Right click on the domain and select Properties from the context menu
  4. Under Type click Change
  5. Select "Active Directory-integrated" and click OK
  6. Click OK to "Are you sure you want this zone to become an Active Directory-integrated"
  7. Click Apply then OK
