Microsoft IIS: Configuring a Domain SSL Certificate

In a previous article, I explained how to host a second web site within IIS and how to configure the server bindings so that both sites (the new site and the default site) were able to listen on “Port 80”.

I would like to expand upon this by adding a Domain SSL Certificate to the server, so that traffic between our newly created web site and the client is encrypted.

Let’s begin by reminding ourselves that the address of the web site we created in the previous article is “http://8g7yf4j-www2” and the default web site is “http://8g7yf4j-win7” (yours may be different of course).


By the end of this exercise, we will have a secure site with an address of “https://8g7yf4j-www2” (note that the “http” prefix is now “https”).

The process is basically two stages:

  1. Create a new Domain SSL Certificate within IIS Manager
  2. Create a new “SSL” binding within IIS Manager

So, let’s get on with creating a new Domain Certificate that will be used to encrypt the traffic.


From within IIS Manager, select the server hosting the web site, and then click “Server Certificates”, and then “Create Domain Certificate”. It is important to select “Domain Certificate”, as it will automatically be trusted by all of the computers within the Domain Network.


Type the host name of the Web Site (8G7YF4J-WWW2) in the Common Name box, and pad out the remaining fields as necessary before hitting “Next”. Remember, this is the host name you entered in the the binding in the previous exercise (not the actual host name of your server).


On the “Certification Authority” screen, The Certificate Authority (in most cases) will be your Domain Controller, and the friendly name will again be your Host Name (8G7YF4J-WWW2). Click “Finish” to create the certificate. It is important that the Host Name stored within the Certificate matches the Web Address, otherwise you will receive a Certificate Error when you visit the Web Page.

The final step is to add a new Binding on Port 443 for the Web Site. You should be familiar with this process from the previous exercise.

IIS Bindings 009

The Details you need to enter into the Binding are shown in the table below.

Type https
Host Name 8G7YF4J-WWW2
SSL Certificate 8G7YF4J-WWW2


Make sure you select “https” as the type (and not “http”). Click “OK” when you are done, and note that you now have two bindings for your Web Site:

  1. Port 80 (Unencryped)
  2. Port 443 (Encrypted)


At this point, you can restart your web server (for good measure), and test the new certificate from a workstation by typing “https://8G7YF4J-WWW2” into a Web Browser.


After the page has loaded, you can click on the padlock icon and view the details of the certificate.
