Hi Maxim Fomin,
Thank you for reaching out to Microsoft Q & A forum.
The Default Domain Policy GPO applies to "Authenticated Users," which is a well-known Security Identifier (SID) in Active Directory. This group includes all entities that have successfully authenticated to the domain, such as users, computers, and services. Unlike "Domain Users," it covers all authenticated accounts, not just those within the domain. This ensures that policy settings are applied broadly. If more specific targeting is needed, Security Groups or WMI filters can be used.
Please feel free to contact us if you have any additional questions.
