I configured a GPO to force the wallpaper for user connecting to our remote session host running Windows server 2008R2. The policy does not seem to function. Enclosed you will find a screenshot of the applied policy. I went through a couple of posts on the forum and also tried the following script:
:: Configure Wallpaper
REG ADD "HKCU\Control Panel\Desktop" /V Wallpaper /T REG_SZ /F /D "\\dc1\Wallpaper\AS-Wallpaper-v2.jpg"
REG ADD "HKCU\Control Panel\Desktop" /V WallpaperStyle /T REG_SZ /F /D 0
REG ADD "HKCU\Control Panel\Desktop" /V TileWallpaper /T REG_SZ /F /D 2
:: Make the changes effective immediately
%SystemRoot%\System32\RUNDLL32.EXE user32.dll, UpdatePerUserSystemParameters
After a ran this script and opened control panel- display- change desktop background and close it straight away. The background image is showed. When I log off and log back on the image is gone. The background color is fine, it is just the image.
