Not sure if it was already mentioned, didnt see it in a quick scan but I had a similar issue. Make sure that DHCP Option 66 and 67 are enabled. 66 should be the IP address of your FOG server and 67 should be your undionly.kpxe file.

I struggled with it for a couple of hours, hopefully it helps you out.
