These guys are insane. Ever heard of 47-boxing? Shit!

If you count the number of PCs, you’ll get 47. My girlfriend controls 23 and I control 23. The other one is a server. All but 2 of those pcs are diskless. It got to the point that updating 46 pcs just took too long, the hard drives added to the electric bill and generated heat, so I found a good PXE solution that works great.
