Hi In my case i forgot to put 3 more files to my PE image, that was the cause for my lsass error. When i launched the soft who makes the PE image, it told me about 3 files error, so i put them manualy on the image disk. I can't remeber wich files that was. Gonna check it up. As for the WinPE with .NET framework i found a good one. And it worked without problems for me... http://www.colinfinck.de PS. Sorry for the long wait, i was on vacation....
