Specifies if a computer performing dynamic DNS registration will register A and PTR resource records with a concatenation of its computer name and a connection-specific DNS suffix, in addition to registering these records with a concatenation of its computer name and the primary DNS suffix.

By default, a DNS client performing dynamic DNS registration registers A and PTR resource records with a concatenation of its computer name and the primary DNS suffix. For example, a computer name of mycomputer and a primary DNS suffix of microsoft.com will be registered as: mycomputer.microsoft.com.

If you enable this policy setting, a computer will register A and PTR resource records with its connection-specific DNS suffix, in addition to the primary DNS suffix. This applies to all network connections used by computers that receive this policy setting.

For example, with a computer name of mycomputer, a primary DNS suffix of microsoft.com, and a connection specific DNS suffix of VPNconnection, a computer will register A and PTR resource records for mycomputer.VPNconnection and mycomputer.microsoft.com when this policy setting is enabled.

Important: This policy setting is ignored on a DNS client computer if dynamic DNS registration is disabled.

If you disable this policy setting, or if you do not configure this policy setting, a DNS client computer will not register any A and PTR resource records using a connection-specific DNS suffix.
