Delete a Resource Record
Applies To: Windows Server 2008
You can use the following procedure to delete a resource record from a Domain Name System (DNS) zone. Resource records remain in a zone until you delete them or they are removed by one of the following:
A pointer (PTR) resource record is deleted automatically if the corresponding host (A) resource record is deleted. For more information, see Providing Reverse Lookup for more information.
A host (A or AAAA) resource record is deleted automatically if the host that had dynamically registered the resource record deregisters the same record. For more information, see Managing Dynamic Update for a Zone.
A resource record is deleted automatically by aging and scavenging. See Managing Aging and Scavenging.
You can perform this procedure by using the DNS Manager snap-in or by using the Dnscmd command-line tool.
Membership in Administrators on the local computer, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure.
