Hello, I have a Win2003 RIS Server with WinPE 1.2. I boot a computer without Hyperthreading in WinPE (using RIS) : all is working. I activate Hyperthreading on this computer : WinPe doesn't work. I'm still on the "please wait" message, at the end of the text setup. I try the patch http://support.microsoft.com/kb/814199/en-us, but it doesn't work. Has someone an idea ? Did someone success to boot in WinPe (using RIS) with an HT processor ? Thank you. Ludo
