| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 0 |
Disables DNS dynamic update registration of PTR records by this DNS client. PTR ("pointer") records associate an IP address with a computer name.
This entry is designed for enterprises in which the primary DNS server that is authoritative for the reverse lookup zone cannot or is configured not to perform dynamic updates. It reduces unnecessary network traffic and eliminates event log errors that record failed attempts to register PTR records.
| Value | Meaning |
|---|---|
| 0 | Register PTR records. |
| 1 | Do not register PTR records. |
Note
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
