Consider the following scenario:

•	You create a scheduled task on a computer that is running Windows Server 2008 or Windows Vista Service Pack 1 (SP1).
•	One or more command-line arguments in this scheduled task are enclosed in quotation marks.

In this scenario, the scheduled task does not run as expected. Additionally, a value of 0×1 appears in the Last Run Result column.

For example, assume that you create a scheduled task by running the following command-line argument:

The scheduled task fails after it starts at 03:15. However, if you delete the quotation marks around 1-Jan-70 8:00:00, the scheduled task runs successfully.

Note The issue does not occur in Windows Vista or in Windows Server 2003.

This problem occurs because Task Scheduler cannot correctly parse quotation marks in a command line.
