DNS zones can be stored in the domain or application directory partitions of Active Directory Domain Services. A partition is a data structure within Active Directory used to distinguish data for different replication purposes.

For a zone to be stored in the specified application directory partition, the DNS server hosting the zone must be enlisted in the specified application directory partition.
