The user specifies which domain controllers are tested, such as all domain controllers within an enterprise or site, or just a single domain controller. The user can also select domain controllers holding a directory partition. In the default mode, minimum output is displayed a confirmation of each test. In the verbose mode, the collected data for each test is displayed.
