OK, here is what is going on with your system. If you don't force Active Desktop to be enabled then your users won't get your backgroud. Make sure you have that set.
The suggestion to just set the color is a good one. I have a customer that wanted to force the desert theme to all computers. I created this login script to set that. You should be able to identify the parts you want and modify it.
Note that because this makes registry changes in the current user area, the changes don't actually show up until the user logs on a second time (first time to set it, second time you see it). We locked the users out from setting this differently so they can't change it, but the script remains active for login all the time.
