Updating DNS client information

Updating DNS client information on a computer is sometimes necessary, for example, when a computer is added or removed from an Active Directory domain. In most cases, clients perform dynamic updates for the following changes when entering or leaving a domain:

  • When a computer is joined to a domain, it adds its A and PTR resource records to DNS.

  • When a computer is removed from a domain, it deletes its A and PTR resource records from DNS.

If you have enabled dynamic update for zones, these changes occur automatically. For more information, see Dynamic update.
