This is Part 2 in my Configuring 802.1x Authentication for Windows Deployment series. Be sure to check out all of the other parts here. Note: I don’t have 802.1x setup in a lab to show how to configure the 802.1x service on the server side. However, I do know that you will need to configure your 802.1x service to allow PXE traffic. I believe that Cisco ISE has a setting already that you can just turn on to allow it.
