The Alerter subkey stores configuration data for the Alerter service. This service sends messages to users warning them of impending resource, security or access problems on the server. Alerts appear in a message box on the user's display. Typically, the Alerter service alerts users when a printer is running out of paper or the disk on a file server is nearly full.
