Creating and Isolating Applications in IIS 6.0 (IIS 6.0)
To create an application, you designate a directory as the starting point (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 by removing it and creating a new application.
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
Isolating applications means configuring them to run in a process (memory space) separate from the Web server and other applications. You can run IIS 6.0 in one of two isolation modes: worker process isolation mode or IIS 5.0 isolation mode. IIS cannot run in both modes simultaneously.
Worker process isolation mode is the default mode that the server runs in on a clean installation. In this mode, you can isolate an application by adding it to an application pool that includes isolation settings. For more information on creating and configuring application pools, see Configuring Application Pools in IIS 6.0.
Before you isolate an application, verify in which application isolation mode the computer is running. You can determine the application isolation mode in which IIS is running by the presence (worker process isolation mode) or absence (IIS 5.0 isolation mode) of the Application Pools folder.
To isolate an application in worker process isolation mode
IIS 5.0 isolation mode allows you to run applications in IIS 6.0 that were developed for earlier versions of IIS. Use this mode only if an application has a compatibility issue when it runs in worker process isolation mode and you cannot resolve the problem.
To isolate an application in IIS 5.0 isolation mode
Server-side include (SSI) and Internet Database Connector (IDC) applications cannot be run in a memory space separate from the Web server.
