  1. In the Health Log referring to the email notifications: “An error occurred while sending email: 0x80040605 Failed to process a request because the target server is unreachable.”

The reason for the error is that the product cannot connect to its background services.


To resolve the issue make sure that the following services are running and their startup type is set to “Automatic“.

  • Netwrix Auditor Archive Service
  • Netwrix Auditor Configuration Server Service
  • Netwrix Auditor Core Service
  • Netwrix Auditor Data Collection Service

Try rebooting the server if the services cannot start.

NOTE.
Netwrix Auditor informs you if you are running out of space on a system disk where Long-Term Archive and Working folder are stored by default. You will see events in the Netwrix Auditor System Health log once the free disk space starts approaching minimum level.
