I have a Server 2003 domain and I'm trying to set a group policy to force a wallpaper. I have a GPO and I assigned it to the OU's I want it to be enforced on. It is a .bmp located in a UNC path. The wallpaper will not always show up for the users it is supposed to. It always show up in the preview window if you right click the desktop > properites and the policy shows as applied in rsop.msc. I've tried every combination of active desktop on/off, only allowing bitmaps, etc and I just can't seem to get this to apply consistently. The bmp is 4mb and I'm thinking that might be some of the issue.
