Path in the GPO console
Computer Configuration\Administrative Templates\Network\DNS Client Description
Specifies if the DNS client will register PTR resource records. By default, DNS clients configured to perform dynamic DNS registration will attempt to register PTR resource record only if they successfully registered the corresponding A resource record. If you enable this policy setting, registration of PTR records will be determined by the option that you choose under Register PTR records. To use this policy setting, click Enabled, and then select one of the following options from the drop-down list: Do not register: the DNS client will not attempt to register PTR resource records. Register: the DNS client will attempt to register PTR resource records even if registration of the corresponding A records was not successful. Register only if A record registration succeeds: the DNS client will attempt to register PTR resource records only if registration of the corresponding A records was successful. If you disable this policy setting, or if you do not configure this policy setting, the DNS client will use locally configured settings.
