The following instructions will guide you through the SSL installation process on Microsoft IIS 8 using a SSL certificate that only secures one domain name. 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. If you still have not generated your certificate and completed the validation process, reference our CSR Generation Instructions.
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.

Select Personal as your certificate store for the new certificate.
8. Click OK
Click OK and the newly installed certificate should appear in the refreshed Server Certificate List.
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…, if you are installing a new certificate and need to create a new binding, click Add. If you are renewing an expiring certificate, click the existing binding and click Edit.
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 Binding, enter the following information:
- Type – Select “https.”
- IP Address – Select “All unassigned.” Now, if you have multiple IP address, select the correct one that applies.
- Port – Enter “443” unless you are listening to SSL traffic on another port (e.g. 992).

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 8
Microsoft IIS 8 is known to generate error message: “Failed to remove the certificate.”
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 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 your 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. Here are some instructions to guide you through the reissue process:
1. Generate a new CSR
Generate a new Certificate Signing Request (CSR) in Microsoft IIS 8.
2. Log in
Log in to your Account Control Panel.
3. Select your Active Certificate
Select your Active Certificate.
4. Click Re-Issue Certificate
Click the Re-Issue Certificate button.
5. Paste your new CSR
Paste in your new CSR.
6. Complete domain validation
Submit and complete domain validation again (if required).
7. Save the new certificate
Save the newly issued SSL certificate on your server’s desktop.
8. Repeat the installation instructions
Repeat the SSL installation process referencing the above instructions.
