JSI Tip 9955. Windows 2000 Task Scheduler job will not start with event ID 7901?

Even though you have applied SP4, you continue to experience the error from Microsoft Knowledge Base article 329962 - Task Scheduler may create corrupted job files.

This behavior will occur if Protected Storage becomes corrupt.

To resolve this behavior:

1. Move the contents of "C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\S-1-5-18" to another folder for safe keeping, causing the S-1-5-18 the sub-folder to be empty.

2. Shutdown and restart Windows 2000.

NOTE: The restart should cause Protected Storage to be rebuilt and your scheduled jobs should run.

NOTE: This solution will also work if you experience these same symptoms on Windows Server 2003 or Windows XP.
