How do I install my SSL certificate on the IIS5 and 6 ?

Installing an SSL certificate on the IIS5 and 6 is quite easy. The IIS Wizard will guide you through all the important steps required to create a CSR and link to the desired web page.

Please note that it is generally not possible to use the CSR generator in conjunction with the IIS web server as it only accepts certificates for which the CSR was generated on the server itself.

After you have successfully ordered and received your SSL certificate, you can start installing it on the web server.

Installing the Server Certificate
  • Click on "Start", then navigate to "Administrative Tools" and click on Internet Information Services (IIS) Manager.
  • Choose "WebSites". Then right-click on the "Default Web Site" and select "Properties" from the options.
  • In the next window, open the "Directory Security" tab and click on the "Server Certificate" button in the "Secure Communications" area. This will open the Certificate Wizard.
  • Click on "Next".
  • Please activate the option "Process pending requests and install the certificate" in the IIS Certificate Wizard.
  • Then click on "Next".
  • Now select "Browse..." and navigate to your SSL certificate. For security reasons, select "view all Types" when selecting the display to ensure that the file is actually displayed.
  • Click on "Next" and complete the next steps in the wizard.
Installing the Intermediate Certificate
  • Upload the intermediate certificate to a folder on your web server.
  • Double-click on the intermediate certificate to display the certificate details.
  • In the "General" tab, click on the "Install Certificate" button to open the Import Wizard. Then click on "Next".
  • In the Certificate Import Wizard select the option "Place all certificates in the following store" and click on "Browse...".
  • Activate the option "show physical stores", expand the folder "Intermediate Certification Authorities" and select the folder "Local Computer".
  • Now click on "OK", then on "Next" and then on "Finish" to complete the installation of the intermediate certificate.
  • It may be necessary to restart the server.

You can check whether the installation of the certificate has worked as desired by simply calling up the website with https instead of http as usual. The SSL Checker on our website offers you a more detailed check of the certificate chain.
