Event ID 105 — Task Scheduler Service Status

Applies To: Windows Server 2008

The Task Scheduler service enables you to perform automated tasks on a local or remote computer. With this service, you can schedule any program to run at any time or when a specific event occurs.

The Task Scheduler service is automatically started by Service Control Manager (SCM). The Task Scheduler service cannot be stopped or disabled by administrators using the Services Microsoft Management Console (MMC) snap-in user interface, unless special permissions are added to the administrator token. The Task Scheduler service uses the Component Object Model (COM) service, the Windows Event Log service, and the Remote Procedure Call (RPC) service; all of these services must be started for the Task Scheduler service to run correctly.
