File access rights using plesk

Running Plesk on a Windows server. I want to set the access rights to a folder so that the .asp files cannot be accessed via a browser, only server side scripts. There is a subfolder with an access database in it that the server side script needs to update. What should I set the access rights to in Plesk?
These are the users
Plesk Domain User (number)
Plesk IIS User (IUSR_number)
Plesk IIS WP User (IWPD_number(number))

I believe you just need to set IUSER_ and IWPD_ to no access.  

If your site is set up like c:\inetpub\\httpdocs\index.asp  You could place your database in c:\inetpub\\mydatabase\db1.mdb and have your scripts access the database and this way the IUSR will not even be involved.
