Install and Configure Your SSL Certificate on Windows Server 2016 with IIS 10

(Single Certificate) How to install your SSL certificate and configure the server to use it

Install SSL Certificate

On the server where you created the CSR, save the SSL certificate .cer file (e.g., your_domain_com.cer) that the certificate authority sent to you.
In the Windows start menu, type Internet Information Services (IIS) Manager and open it.
In Internet Information Services (IIS) Manager, in the Connections menu tree (left pane), locate and click the server name.

On the server name Home page (center pane), in the IIS section, double-click Server Certificates.
On the Server Certificates page (center pane), in the Actions menu (right pane), click the Complete Certificate Request… link.

In the Complete Certificate Request wizard, on the Specify Certificate Authority Response page, do the following and then click OK:
- File name containing the certificate authority's response: Click the … box and browse to and select the .cer file (e.g., your_domain_com.cer) that the certificate authority sent to you.
- Friendly name: Type 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 certificate authority's name and the expiration date to the end of your friendly name, for example: yoursite-authority-(expiration date). This information helps identify the issuer and expiration date for each certificate. It also helps distinguish multiple certificates with the same domain name.
- Select a certificate store for the new certificate: In the drop-down list, select Web Hosting.

Now that you've successfully installed your SSL certificate, you need to assign the certificate to the appropriate site.

Assign SSL Certificate

In Internet Information Services (IIS) Manager, in the Connections menu tree (left pane), expand the name of the server on which the certificate was installed. Then expand Sites and click the site you want to use the SSL certificate to secure.

On the website Home page, in the Actions menu (right pane), under Edit Site, click the Bindings… link.
In the Site Bindings window, click Add.

In the Add Site Bindings window, do the following and then click OK:
- Type: In the drop-down list, select https.
- IP address: In the drop-down list, select the IP address of the site or select All Unassigned.
- Port: Type port 443. The port over which traffic is secure by SSL is port 443.
- SSL certificate: In the drop-down list, select your new SSL certificate (e.g., yourdomain.com).

Your SSL certificate is now installed, and the website configured to accept secure connections.
