Creating Applications in IIS 6.0 (IIS 6.0)
To create an application, you must first designate a directory as the starting point, which is also called the application root, for the application. You can then set properties for the application. Each application can have a friendly name. This name appears in IIS Manager and gives you a way to distinguish between applications. The application name is not used anywhere else.
Web sites are root-level applications by default. When you create a Web site, a default application is created at the same time. You can use this root-level application, remove it, or replace it with a new application.
You can remove a directory from the application boundaries so that requests to files in that directory and its subdirectories cannot start the application. Removing a directory from an application boundary does not delete the directory from either your Web site or from your computer's hard disk.
Important You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /user:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
To create an application
If you see the Remove button instead of the Create button, an application has already been created.
To remove a directory from the application
To stop an application and unload it from memory, click Unload. If the Unload button is dimmed, you are not in the application's starting-point directory.
