Joel you are correct although I haven't tracked it down just yet. I just connected to a Vista machine off our domain through RDP where I have access to my local drives. I performed the same procedure and it worked. I am not certain what is specific to Vista that prevents a registry hive from loading where it does allow it on XP. Again the Vista and XP machines are under the same OU with the exact same policies applied. I know this isn't a KIX issue but I had tunnel vision as to why my KIX script stopped working.
