    Additional Information


    Settings are applied in the following order through a Group Policy Object (GPO), which will overwrite settings on the local computer at the next Group Policy update:

    Local policy settings
    Site policy settings
    Domain policy settings
    OU policy settings

      When a local setting is greyed out, it indicates that a GPO currently controls that setting.
