New: IIS 7 installation video walkthrough

After DigiCert issues your SSL Certificate, you first need to install the certificate on the server from which you generated the certificate signing request (CSR). Then, you can assign or bind the certificate to the appropriate website.

Installation:

Using IIS 7 to Install the SSL Certificate

  1. Open the ZIP file that contains your SSL Certificate and save the SSL Certificate file (your_domain_name.cer) to the desktop of the web server that you are securing.

  2. Open Internet Information Services (IIS) Manager.

    In the Windows Start menu, click Administrative Tools > Internet Information Services (IIS) Manager.

  3. In Internet Information Services (IIS) Manager, under Connections, select your server’s Hostname.

  4. In the center menu, in the IIS section, double-click the Server Certificates icon.

  5. In the Actions menu, click Complete Certificate Request to open the Complete Request Certificate wizard.

  6. In the Complete Certificate Request wizard, on the Specify Certificate Authority Response page, under File name containing the certification authority’s response, click to browse to the .cer certificate file that DigiCert sent you, select the file, and then, click Open.

  7. Next, in the Friendly name box, enter a friendly name for the certificate. The friendly name is not part of the certificate; instead, it is used to identify the certificate.

    We recommend that you add DigiCert and the expiration date to the end of your friendly name, for example: yoursite-DigiCert-expirationDate. This information helps identify the issuer and expiration date for each certificate. It also helps distinguish multiple certificates with the same domain name.

  8. To install the SSL Certificate to the server, click OK.

Additional Information

Troubleshooting:

  1. If your web site is publicly accessible, our SSL Cert Tester tool can help you diagnose common problems.

  2. Open a web browser and visit your site using https. It is best to test with both Internet Explorer as well as Firefox, because Firefox will give you a warning if your intermediate certificate is not installed. You should not receive any browser warnings or errors. If you immediately receive a browser message about the site not being available, 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 blocking traffic on TCP port 443 to the web server.

  3. Note for ISA servers: If your ISA 2004 or 2006 server is not sending the intermediate certificate, you need to fully reboot the server. We have confirmed this to be true with many customers: ISA server will not properly send the intermedate certificate chain until after a full reboot.
