Webservices and HTTP Error 404.3

When viewing a new webservice setup in IIS 7, you get the following error:

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.

Check that you have installed the WCF Activation component for IIS.
  1. Open Server Manager, click Start > Server Manager
  2. From the left panel in Server Manager, click on Features
  3. Click on Add Features
  4. From the available list of features, scroll down and select .Net Framework 3.0 Features and then WCF Activation, then click Next
  5. On the Confirmation page, click on Install
  6. Installation of the selected feature will be initialized and started
  7. Once installation is completed, click on Close
