7021403: IIS 404.3 Error After Installing Retain



HTTP Error 404.3-Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is script, add a handler. If the file should be downloaded, add a MIME map.

Even after the ISAPI Extensions and ISAPI Filters are installed, the error still occurs.

How do you resolve this error and allow access to the Retain Server interface?
