I'm running Windows 7 Enterprise on all my desktops. I've used Group Policy Preference to copy the wallpaper to all workstations on the network (C:\Windows\Web\Wallpaper\Architecture\wallpaper.jpg). I used Group Policy to push out the wallpaper policy i.e. enable desktop wallpaper, prohibit changes, enable active desktop. Some of my desktops are coming up with just a black background and not displaying the wallpaper. If I run "gpresult /r" I can see the wallpaper policy was applied to computer. If I go into Control Panel and look at the display properties under Personalization I can see the wallpaper is there but not displaying correctly. Any suggestions would be gladly appreciated.
