The Alerts dialog box displays and manages the list of users and computers that are notified when administrative alerts occur at a selected computer.
Administrative alerts are generated by the system and relate to server and resource use. They warn about security and access problems, user session problems, server shutdown because of power loss when the UPS service is available, and printer problems.
For alerts to be sent, the Alerter and Messenger services must be running on the computer originating the alert. For alerts to be received, the Messenger service must be running on the destination computer.
For more information, see "Managing Administrative Alerts," "Starting and Stopping Services," and "Configuring Service Startup" in Server Manager Help.
