This security setting determines whether to audit each instance of a user exercising a user right. 

If you define this policy setting, you can specify whether to audit successes, audit failures, or not audit this type of event at all. Success audits generate an audit entry when the exercise of a user right succeeds. Failure audits generate an audit entry when the exercise of a user right fails. 

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.
