Imaging software

Does anyone know of a good piece of imaging software that can clone a hard drive of one machine and apply it to multiple machines at the same time over a LAN? I am after something that is preferbly not in Linux as I don't really understand all of this Linux stuff. By the way, it has to be free, I know there is Norton Ghost, Acronis etc... but if there's a free product lurking around this would be better!

Cheers!
