Description

Disables the Domain Name System (DNS) dynamic update registration of PTR (pointer) records by this DNS client. PTR 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.

This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
