I am also getting the same blank UNC error. Any luck in figuring out what that was? I am surprised I haven't found a straight forward guide of setting up a custom image, firing off litetouch.vbs to caprture/sysprep it the network, and then setting WDS/LiteTouch to push it back down to new machines. What seemed to be an easy setup, sysprep.exe, ghost up and ghost down procedure sure has gotten complicated : )
