Hello,
If you encounter a problem with your Symantec Endpoint Protection Manager (SEPM) database, Symantec Support may ask you to run the Database Validation tool to assist in diagnosing the problem. The batch file, dbvalidator.bat, is located by default in Program Files\Symantec\Symantec Endpoint Protection Manager\Tools folder. This tool creates a log file that is called dbvalidator.log, which is placed in the Program Files\Symantec\Symantec Endpoint Protection Manager\tomcat\logs folder.
