Application pool issue

Hi all,

I have configure IIS with multiple .net applications and coldfusion sites.

All are running under the same DefaultApplicationPool.

I add a new coldfusion site an I Add Application with different Application Pool. Getting error:

HTTP Error 403.18 - Forbidden

The specified request cannot be processed in the application pool that is configured for this resource on the Web server.

Most likely causes:

• An ISAPI filter or custom module changed the URL to run in a different application pool than the original URL.
• An ISAPI extension (or custom module) used ExecuteURL (or ExecuteRequest) to run in a different application pool than the original URL.
• You have a custom error page that is located in one application pool but is referenced by a Web site in another application pool. When the URL is processed, it is determined by IIS that that it should have been processed in the first application pool, not the other pool.
• The Web site has multiple applications configured. The application this request is configured to run in is set to run in an application pool that does not exist

 Found couple articles but no luck.

Any ideas how to solved this issue?

Thanks, Johnny
