You can prevent users from changing *DNS using Active Directory Group Policy*. See Microsoft's online guides for more information on Group Policy Objects (GPOs).

Another improvement is to *create some rules on your router/firewall* to automatically redirect DNS requests from PCs to the private IP address of the DNS Proxy.

In this way, internal devices configured to use a *DNS other than the Proxy DNS IP will be filtered using the default DNS filtering policies*.


**IMPORTANT**: This rule should be applied to all IPs except the Proxy DNS.
