I (tobor), demonstrate how to set up Secure Only Dynamic DNS updates on Windows Server 2022.

If you are NOT using best practices, running your DHCP service on your Active Directory server you will need to execute the below command to apply least privilege.
CMD: dnscmd /config /OpenAclOnProxyUpdates 0
