You'll need to get on some PXE forums or support sites for working with PXE. I never got into using it. I did review some of it years ago however found it a bit too complicated and went with Nortons Ghost Server and Ghost imaging platform for a lab I did. We had boot CDs for each PC that needed to be imaged and users could select what images they needed, the PC ran the boot and ghost script and selected the desired image files from the Ghost Server which had 2 RAID drives for max storage. Ran well. There was a Server 2003 set up as a subnet server handing out IPs and Internet for the lab, All other PCs and the Ghost server was all connected via Gb Switch to the 2003 Server PC.
