What is the IE Task Scheduler?
A task scheduler is a utility that lets administrators submits tasks for execution at a specified time. For instance, an administrator might use a task scheduler to automatically start a backup process at the same time every day. Windows NT has a native task scheduler, known as the Schedule Service or the “AT Service” IE 5 delivers a new task scheduler that replaces the native Windows NT service. Tasks that are scheduled for execution via the Task Scheduler are known as “AT jobs”.
