This service is disabled and isn't loading or starting in Windows XP Home SP2, Professional SP2, Home SP3, Professional SP3. When the Alerter service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other services and drivers are allowed to run in the same process. If the Alerter fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the Alerter service has failed to start.

Alerter depends on the Workstation service.
