I still can't find what's preventing it from working.. i'm quite sure we're missing something here, after the "policy" issue my RSoP (Resultant Set of Policy) is unusable. Any ideas? I still don't understand how the policies are related to the registry data Maybe an stuppid idea. But is it possible to copy and overwrite every file from Vista to Server 2008. And just copy the Registery of Vista to Server 2008 and overwrite everything? Then is must be working... If NOT, it's not possible.... I Suppose.... The regserv32.exe command... That registers some file, does he save that in the Registery :S ? I think if we test this, we get an Vista machine with some extra (not over-written) files. Everything must be the same as Windows Vista... Is this possible? And your program w-desing, is the VMWare workstation needed? When I start the wizard: "New Acquisition", I can't "browse" to the files :S
