Have a look at http://www.cafemaster.net/CM/ for billing and Deepfreeze for config and support. Deepfreeze is a cool program if a client does change the OS settings (and they will no matter what us set) i.e. virus, just restart and it is back to your original config, cost a bit but does save time and is earier than having someone re ghost as all they have to do is restart. Half the cafes in london use this. inom...
