The following instructions will guide you through the SSL installation process on Microsoft IIS 7. If you have more than one server or device, you will need to install the certificate on each server or device you need to secure.
What You’ll Need?
1. Your server certificate
This is the certificate you received from the CA for your domain.
2. Your intermediate certificates
These files allow the devices connecting to your server to identify the issuing CA. There may be more than one of these certificates.
3. Your private key
This file should be on your server, or in your possession if you generated your CSR from a free generator tool. On certain platforms, such as Microsoft IIS, the private key is not immediately visible to you but the server is keeping track of it.
Installation Instructions:
1. Launch IIS Manager
Click Start, Control Panel, Administrative Tools, and then select Internet Information Services (IIS) Manager.
2. Select your server name
In the left Connections menu, select the server name (host) where you want to install the certificate.
3. Navigate to the Security section
In the center menu, click the Server Certificates icon under the Security section near the bottom.
4. Click Complete Certificate Request
In the right Actions menu, click Complete Certificate Request.
5. Browse to your Server Certificate
In the Complete Certificate Request wizard, click “…” to browse and select Your Server Certificate file that was previously saved on your server’s desktop.
6. Name your certificate
Enter a Friendly Name which is an internal reference name to distinguish the file later. We recommend including the CAs name and expiration date.
7. Click OK
Click OK and the newly installed certificate should appear in the refreshed Server Certificate List.
Note: If you receive an error during this step, please reference the “Known Error Messages in IIS 7” section below.
Binding Your Certificate to Your Website
Now, proceed with the remaining steps which will help you assign or bind the SSL certificate to the appropriate website.
1. Access your Sites folder
From the left Connections menu, expand your server’s name, expand the Sites folder, and then select the site (e.g. Default Web Site) that you want to secure.
2. Click Bindings…
In the right Actions menu, click Bindings…
3. Click Add
In Site Bindings…, click Add.
Note: If you already have the appropriate site binding created, click “Edit” and change the SSL Certificate accordingly.
4. Input the following
In Add Site Bindings, enter the following information:
- Type – Select “https”.
- IP Address – Select “All unassigned”. Now, if you have multiple IP addresses, select the correct one that applies.
- Port – Enter “443” unless you are listening to SSL traffic on another port (e.g. 992).
- SSL Certificates – Select the “friendly name” of the SSL certificate you just installed. You can always click “View” to confirm the certificates validity details.
5. Click Ok
Click Ok to finish binding the SSL certificate to your live website.
Congratulations! You’ve successfully installed your SSL certificate! To check your work, visit the website in your browser at https://yourdomain.tld and view the certificate/site information to see if HTTPS/SSL is working properly. Remember, you may need to restart your server for changes to take effect.
To check your server’s configurations more thoroughly, use our SSL Checker Tool or contact our Customer Experience Department for additional assistance.
Known Error Messages in IIS 7
Microsoft IIS 7 is known to generate one of the two error messages: “Cannot find the certificate request associated with this certificate file. A certificate request must be completed on the computer where it was created.” And “ASN1 bad tag value met.”
If you are certain this is the same server where you generated the CSR, then the error may be meaningless and the certificate may have been correctly installed. To test this, close the dialog and click “F5” to refresh the list of server certificates. The new certificate should now be in the list, and you can continue with the next step.
However, if the newly installed certificate does not appear in the server certificate list, we recommend you re-issue the certificate with a new CSR and attempt the installation process again.
