When installing ColdFusion on Vista or on Windows Server 2008 you may receive HTTP 404.3 Error, similar to this one:
HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
Additionally if you run ColdFusion Web Server Configuration Tool, you will see a message saying that IIS components are being installed and could take between 2 to 5 minutes of time.
You can resolve this error by making sure that the two required components of IIS are installed on your system. Namely:
- ISAPI Extensions
- IIS Metabase and IIS 6 configuration compatibility.
