Nerdpedes,

Best of:
I can capture a full machine image. Do your systems automatically connect to the domain controller after setting up the machine? If so, this image probably has domain controller credentials on it, that I can capture and use elsewhere.
Computer makes a DHCP request --> DHCP server responds with address and PXE parameters --> Computer downloads boot image using TFTP over UDP
If the good guys got the traffic on that low level, unencrypted. Then they would have it all.
I'm not really arguing with you, you are correct, it's possibleto fit it all in ram, just not likely. That said the image for the voting machines is probably pretty stripped down and much smaller than a standard windowsimage. I have similar at work, but our image is still in the 40-50 gig range. .wim stands for windows image file. Usually it is a presetup windows machine at 20+ gigs. From my experience. I service machines for a company that use pxe for deployment and will often image many machines at once. Not saying you are wrong tho.
