We have over 250 computers plus 100 thin clients in just 1 lab. Our computers warranty will or has ran out. I am looking for a way in converting our pc to thin clients via pxe boot (no cd, no usb, no OS, etc). Has anybody tried it? I've been researching for a while but all of my findings have come up with using third party software. So looking for the best, cheap, FREE way to do it.
