i vaguely remember using vnc along time ago, but i also remmebr that when i had to set it up , i had to go to each machine , install it and also allow access to the windows firewall ports. i will give italc a try and see how it runs, i have about 300 machines, i install alot of the software through msi's form AD but on some of the older sherston stuff it requires a local copy install so the disc doesnt have to be inserted, i wouldve done all the machiens on a perfect ghost but that would be pointless for year groups not in use of the software
