Remove an Application Pool (IIS 7)

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

If an application pool does not have any applications assigned to it, you can remove the application pool. However, if the application pool has applications assigned to it, you must assign those applications to another application pool before removing the original application pool. Applications cannot run unless they are associated with an application pool.


IIS applications anywhere in a site's directory structure can run in the Default Application Pool if they have the appropriate permissions. If you remove the Default Web Site for security reasons, the Default Application Pool is also removed. Therefore, you must make sure that you have already assigned all applications on your Web server to other application pools.


For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required for this procedure, see Application Pools Feature Requirements (IIS 7).
