I have used LogonStudio on Vista x32 with no problems. Today, I installed Windows Server 2008 x64 on another PC, and it is virtually identical to Vista - I even use Vista drivers in it.
But LogonStudio does not work. When I hit apply, it "locks" the machine to show the new logon screen, but it's the same default one.
I realize this may be hard to track down, but I have not found any Vista software yet that does not work on Win Srv 2K8. Anyone have an idea what I could look for, maybe a File folder is missing or something? Any way to get mnore data on the failure?
