Event ID 202 — Task Monitoring and Control
Applies To: Windows Server 2008
The history of a task is tracked by events. These events can be viewed in Task Scheduler for each task to track when the task was registered, run, and when it completed or failed. The progress of a task can be monitored through its history. A task can be controlled by running or stopping the task manually (on-demand).
