I am experiencing the same problem. I did a lot of work 3 months ago to try to correct it, but no luck. We had 100+ teacher and student devices to image before the summer end, so I had to put it off. I decided to just do thin-imaging in the meantime. Also, Netbooting from our Mac Server didn't work a few months ago either, and neither did DeployStudio.
Out of box mac with LANDesk installed, and then we just ran the Post-OS and System Configuration section of our provisioning template.
Some people on the Jamf forums got some luck, but it seems like a workaround.
