JSI Tip 7642. Windows 2000 and Windows NT Scheduled Tasks do NOT run after a daylight-saving time change?

After the daylight-saving time change, scheduled tasks whose Run As was the administrator's user name, now show the current user, or a blank.

NOTE: If you reset the Run As to the administrator's user name, and set the password, the tasks will run.

NOTE: The Schedlgu.txt file has entries similar to:

The attempt to retrieve account information for the specified task failed; therefore, the task did not run. Either an error occurred, or no account information existed for the task. The specific error is: 0x8004130f: No account information could be found in the Task Scheduler security database for the task indicated.

This problem only occurs if your computer's System partition use the FAT files system. On NTFS file systems, the files maintain their original time stamp during a daylight-saving change, but FAT based files actually change.

To prevent this problem, I strongly recommend that you upgrade to the latest service pack available, AND convert to NTFS.

NOTE: Open a CMD prompt and type CONVERT /?.
