Network access: Let Everyone permissions apply to anonymous users
Applies to
- Windows 11
- Windows 10
Describes the best practices, location, values, policy management and security considerations for the Network access: Let Everyone permissions apply to anonymous users security policy setting.
Reference
This policy setting determines what other permissions are granted for anonymous connections to the device. If you enable this policy setting, anonymous users can enumerate the names of domain accounts and shared folders and perform certain other activities. This capability is convenient, for example, when an administrator wants to grant access to users in a trusted domain that doesn't maintain a reciprocal trust.
By default, the token that is created for anonymous connections doesn't include the Everyone SID. Therefore, permissions that are assigned to the Everyone group don't apply to anonymous users.
Possible values
Enabled
The Everyone SID is added to the token that is created for anonymous connections, and anonymous users can access any resource for which the Everyone group has been assigned permissions.
Disabled
The Everyone SID is removed from the token that is created for anonymous connections.
Not defined
