Configuring IIS to use the machine certificate

 Start up the IIS management console – for example by going to the Control Panel, opening “Administrative Tools”, and the opening “Internet Information Services”.

Double click on your local computer, then “Websites”, and highlight “Default Web Site”

Under the “Action” menu, select “Properties”, and then the “Directory Security” tab:

Click on the “Server Certificate” button and select “Next” when you see the wizard.  Then highlight the “Assign an existing certificate” radio button:

Click “Next”, highlight an appropriate certificate (e.g. the one you just installed), and press “Next” again.

You'll be shown certificate details, and on pressing “Next” one more time you'll be asked to “Finish”.

IIS is now configured to accept your machine certificate.
