I have been utilizing Sysprep and Ghost for many years with no issues of duplicate SID's. We recently upgraded our AutoCad Lab to AutoCad 2010 and decided to use Windows XP 64BIT instead of Windows 7. I created an image as usual, used Sysprep and then pushed the image up. Now all of the machines in that lab show the same SID.I have used Sid Changer in the past to resolve issues where someone forgot to run Sysprep, but never on XP 64BIT.Has anyone else experienced this with XP 64BIT and Sysprep not changing the sids?1 person needs an answerI do too
