scheduled task password

I have the following folder structure:

- root (main application - production)
- subfolder QA set up as Web Application (application for tests)
- root contains web.config and QA contains web.config
- my application uses form authentication


I have a method "MoveToArchive" that calles appropriate StoredProcedure and cleans up my DB. Now I want this to be a scheduled task. This should be password protected task.

So, the questions is:
- should I create new web site from VisualStudio and put there may method?
- if yes - should I create a subfolder in my QA folder for test and in my root folder for production (say, in fulder ScheduledTask)
- how to create password protected file, should I put some web.config in this ShceduledTask folder?
- if yes, how to configure it to use username/password protection and doesn't this folder inherits root folders web.config file?

THank you.

 

Does this work if my root application uses Form authentication?

 

3) To password protect the page, simply follow the instruction on this KB article. http://support.discountasp.net/KB/a3...-in-iis-7.aspx
