In order to run a system service correctly using a user account, you may be required to manually set your user account to have the "Log on as a service" right. The method of doing this varies between versions of Windows NT and Windows 2000/XP/2003.

    To set the "Log on as a service" user right on Windows 2000/XP/2003:

      Bring up the System Policies program from the Administrative Tools group on the Start Menu. Select the User Rights Assignment from the Domain Policies section. Highlight the Log on as a service item in the Policy list. Select Security from the Action item on the menu. You'll be presented with the Policy Setting screen.
