I'm having a problem running a scheduled task in Windows 2003 server, it ran for 4 hours, now it won't start up again.

I will tell you exactly what I have done to create the task, please tell me if I am doing anything wrong.

My objective is to have my task (console app) run every 30 minutes.

1. I open control panel, scheduled tasks, add new scheduled task
2. Browse for my application I want to run, a console app without any command line arguments
3. I select, perform this task - Daily
4. I select the start time (now 8:00 in the morning)
5. Start date set to today
6. Set the correct username + password
7. Open advanced properties
8. Repeat the task every 30 minutes for 24 hours

Save and close.

Anything wrong in the above mentioned steps I've implemented?

Thanks in advance.
