I've appllied wallpaper to Win XP and Win7 PCs through group policy and it is getting applied to all these PCs. My problem is when I change wallpaper jpeg file in server, wallpaper is not automatically changing in client PCs for long time. New wall paper is displayed only after logging off or restart the PCs. I've set the grooup policy refresh interval as 30min. But still its not working. Other policies are working without logoff or restart.
Anyone have any advice. Pls help
