You can use the following procedure to delete a resource record from a zone. Pointer (PTR) resource records are deleted automatically if the corresponding address (A) resource record is deleted.

You can perform this procedure by using the DNS snap-in or by using the Dnscmd command-line tool.

Administrative credentials

To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using the Run as command to perform this procedure.

  1. Open the DNS snap-in.

  2. In the console tree, click the applicable zone.

  3. In the details pane, right-click the resource record that you want to delete, and then click Delete.
