Audit policies must be configured to ensure that events are logged whenever any activity occurs.
Log in to ADAudit Plus' web console → Click on the File Audit tab → Select Windows File Server from under the Configured Server(s) drop-down list → Click on Configure Audit Policy in the right corner above the table view.
This will create a Group Policy object (GPO) [domainname_ADAuditPlusPolicy] and set the required audit policies for Windows file server auditing.
