Ensure 'Configure DNS over HTTPS (DoH) name resolution' is set to 'Enabled: Allow DoH' or higher


This setting determines if DNS over HTTPS (DoH) is used by the system. DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution over the Hypertext Transfer Protocol Secure (HTTPS). For additional information on DNS over HTTPS (DoH), visit: Secure DNS Client over HTTPS (DoH) on Windows Server 2022 | Microsoft Docs.

The recommended state for this setting is: Enabled: Allow DoH. Configuring this setting to Enabled: Require DoH also conforms to the benchmark.


DNS over HTTPS (DoH) helps protect against DNS spoofing. Spoofing makes a transmission appear to come from a user other than the user who performed the action. It can also help prevent man-in-the-middle (MitM) attacks because the session in-between is encrypted.


If the option Enabled: Require DoH is chosen, this could limit 3rd party products from logging DNS traffic (in transit) as the traffic would be encrypted while in transit. The Require DoH option could also lead to domain-joined systems not functioning properly within the environment.

The option Enabled: Allow DoH will perform DoH queries if the configured DNS servers support it. If they don't support it, classic name resolution will be used. This is the safest option.

Note: Per Microsoft, don't enable the Enabled: Require DoH option for domain-joined computers as Active Directory Domain Services is heavily reliant on DNS because the Windows Server DNS Server service does not support DoH queries.


To establish the recommended configuration via GP, set the following UI path to Enabled: Allow DoH (configuring to Enabled: Require DoH also conforms to the benchmark):

Computer Configuration\Policies\Administrative Templates\Network\DNS Client\Configure DNS over HTTPS (DoH) name resolution

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template DnsClient.admx/adml that is included with the Microsoft Windows 10 Release 21H2 Administrative Templates (or newer).

Default Value:

Disabled. (The computer will use locally configured settings.)
