Windows 7 scheduled task returns 0x2

If you look on your task properties, there is the Conditions tab. Any of these conditions could stop the task. For instance, if you have Start the Task only if running on AC Power and Stop task if the computer switches to battery power, and you unplugged your laptop, that would cause this exit condition.

Same goes from Start only if only has been idle for ... and Stop if no longer idle.

That's just an example of anything on that tab which could cause it not to run or stop running prematurely.
