Open IIS by navigating to ‘Start –> Administrative Tools –> Internet Information Services (IIS) Manager’.
Once IIS Manager has opened, on the left side click on the site for which you would like to add or edit the SSL bindings. Then choose Bindings… on the right side.
A new window will open which will allow you to choose an existing binding or add a new SSL binding. To edit an already existing binding, click it once to highlight it and then choose Edit… For this article, we will continue with adding a new one. Click the Add… button.
Now, use the Type drop down menu to choose HTTPS, the IP Adress menu to select the proper IP address, and the SSL Certificate menu to choose the proper certificate.
