| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 2 | 3 | 1 |
Determines whether the DNS server updates the resource records of standard primary zones when the fully qualified domain name (that is, the name or the primary DNS suffix) of the local computer changes.
This entry establishes criteria for zone updates. If a zone meets the criteria, then, when the fully qualified domain name of the local computer changes, the DNS server updates the host name on resource records that include the local computer name, such as SOA, NS, and A records. Otherwise, the records are not updated when the computer name changes.
| Value | Meaning |
|---|---|
| 0 | No zones. The DNS server does not update resource records when the local computer name changes. |
| 1 | Dynamic update zones. The DNS server only updates resource records of standard primary zones that permit dynamic updates. |
| 2 | No dynamic update zones. The DNS server only updates resource records of standard primary zones that do not permit dynamic updates. |
| 3 | All zones. The DNS server updates the resource records of all standard primary zones. |
DNS reads its registry entries only when it starts. You can change entries while the DNS server is running by using the DNS console. If you change entries by editing the registry, the changes are not effective until you restart the DNS server.
