Hardware Diagnostics

[johnnyblackout]

I currently use a bootable usb flash drive, loaded with quicktech, to do all my hardware diagnostics. I was wondering if anyone new of a way that I could get another piece of software that sits on a server and allows machines to pxe boot off of it (and do the hardware diagnostics). Basically I don't want to have to plug the thumb-drive into each machine, I want the laptop/desktop to just boot off the network and start the diagnostics.
