Creating Application Pools in IIS 6.0 (IIS 6.0)


This feature of IIS 6.0 is available only when running in worker process isolation mode.

With IIS 6.0 running in worker process isolation mode, you can group Web applications into application pools. Application pools allow specific configuration settings to be applied to groups of applications, and the worker processes servicing those applications. Any Web directory or virtual directory can be assigned to an application pool.

By creating new application pools and assigning Web sites and applications to them, you can make your server more efficient and reliable, and your other applications always available, even when the applications in the new application pool terminate.


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 a new application pool


In IIS Manager, double-click the local computer, right-click Application Pools, point to New, and then click Application Pool.


In the Application pool ID box, type the name of the new application pool.


Under Application pool settings, click either Use default settings for new application pool or Use existing application pool as template.


If you selected Use existing application pool as template, from the Application pool name list box, click the application pool to be used as a template.


Click OK.
