There are a couple of ways of handling this.
The first is with a Windows Scheduled Task. On the system you want to submit the job every day, go to Start->All Programs->Accessories->System Tools->Task Scheduler
Just write a small script to submit a new Windows HPC job (you can export the xml from a previous job and use it to create the new ones).
Then use the Windows Scheduled Task to submit a new job every day.
The second approach is to have a task in your job create and submit a new job. That way you have a self perpetuating job. You can use the holduntil property on the job to make sure it doesn't run before a certain time (e.g. if you want the job
to run sometime after 6 PM, then use holduntil to keep it from running before 6:00 PM)
