Audit system events  This security setting determines whether to audit when a user restarts or shuts down the computer or when an event occurs that affects either the system security or the security log.  If you define this policy setting, you can specify whether to audit successes, audit failures, or not audit the event type at all. Success audits generate an audit entry when a system event is executed successfully. Failure audits generate an audit entry when a system event is attempted unsuccessfully.  To set this value to No auditing, in the Properties dialog box for this policy setting, select the Define these policy settings check box and clear the Success and Failure check boxes.  Default:  Success on domain controllers. No auditing on member servers.
