Possible Cause: The services were restarted. However, the database that was populated by prior rounds of discovery was used while restarting the services
The machines that have already discovered during the previous cycles of discovery are not removed if ZENworks Server Management services are restarted with a changed scope without resetting.
Action: Copy the empty database and restart the services with the new scope.
WARNING: If you copy the empty database, the configuration information about alarms, health reports, etc., is lost.
