shutdown and backup startup in NT

Hi all,
How to schdule a shutdown, backup and startup of DB in NT - like cron - using the AT command. I tryed this but didn't work :
C:\ AT 20:30 /every:1,2,3,4,5,6 smart
where smart is the batch file that stops the DB, back it up and start it again. It says that the job is schduled but it never happen. I checked for the Schdule service in Control Panel-->Services, there is 'Task Schduler' service and it's started. What could be the problem.

Thanks in Advance...

Did the smart script work properly on the command prompt?

Hi,
Yah, the script is working properly form the command prompt.

hi,

you can use scheduled tasks under control panel. It has a scheduled task wizard. You just need to add your startup and shutdown scripts there. I think it's much simpler and less complicated than using @.
