Any ideas?

Hi, 
Have you distributed the both an x86 and x64 boot image to the DP with the PXE role activated? and the checkbox on the boot images Use this for PXE boot is set as well?

Itlooks like that is the issue.

Hi, It turns out the boot image that was being deployed was not pxe enabled...

I had also not set the Checkbox for use for PXE on one of the boot images.

Sorted Now!
