You can use the following procedure to disable recursion on the Domain Name System (DNS) server.

If you disable recursion on the DNS server, you will not be able to use forwarders on the same server.

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.
