Note: This guide assumes you have a Windows server, it is joined to a domain and you have an account that is part of the domain admins group.


 

First we need to install ADFS 2.0

  1. To install version 2.0, it first needs to be downloaded and installed. Click this link to download the installation file https://www.microsoft.com/en-au/download/details.aspx?id=10909
  2. Choose the type of installation file based on your OS (I am running Server 2008 R2 so I will choose RTW\W2K8R2\amd64\AdfsSetup.exe). Save the installation file to your Desktop
  3. Run the exe located on your desktop
  4. On the Welcome screen, click Next
  5. Accept the License Agreement.
  6. I will be setting this ADFS server as a Federation server so I will leave the default of Federation Server selected and I will click Next. Note: you would select Federation server proxy if you were running your ADFS server in something like a DMZ.
  7. Click Next on the prerequisite software screen. The install wizard will install these automatically if they are not already present on the system. If there are no errors, the software will be installed and the ADFS 2.0 management window will open
