I've had issues with newer systems having issues with various imaging 
issues. Haven't you that program in some time, but my g4l project includes a 
udpcast option that I use to send out an image to multiple machines.

I also setup on lab, and made a partition on the hard drive to store the 
image, and made a setup with an ntfsclone image, where it could reimage 
machines in about 10 minutes with no additional network traffic. 

So, depending on your needs, there may be other options that might handle 
your needs.

I was wondering if the issue I am seeing could be caused by pxelinux since it basically is loading a Linux kernel then booting a MSDos.imz file.  I cannot find any errors from the ghostcast side or the ghost error file.
