You can use the following procedure to modify an existing resource record in a zone. 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.
