Once you have received your SSL certificate from networking4all.com, you will need to install it to the server from which the certificate request was generated.
Save the certificate.
Once the SSL certificate has been successfully installed to the server, you will need to assign that certificate to the appropriate website using site bindings.
From the "Connections" menu in the main Internet Information Services (IIS) Manager window, select the name of the server on which the certificate was installed.
Under "Sites," select the site to be secured with SSL.
From the "Actions" menu (on the right), click on "Bindings." to open the "Site Bindings" window.
Your SSL certificate is now installed, and the website is configured to accept secure connections.
Use a web browser to visit your site using https. Test with both IE and Firefox, as Firefox looks to your server to find your intermediate certificate (IE does not). You should not receive any browser warnings or errors in any browser. If you immediately receive a browser error about “site unavailable”, then IIS 7 may not yet be listening on port 443. If your web request takes a very long time, and then times out, a firewall could be blocking traffic on TCP port 443 to the web server.
