You can use the following procedure to modify an existing resource record in a zone. You can perform this procedure by using DNS Manager or by using the Dnscmd command-line tool.

Membership in the Administrators group, 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 (http://go.microsoft.com/fwlink/?LinkId=83477).
