default theme for all users in XP

I’m setting up a ghost image for my company and I want to have it so when any user logs in it has a preset desktop (IE:company logo on wallpaper, and standardized settings for all users.) The problem is that the only way I see XP allows you to do this is by setting up active destop and setting up a group policy in MMC. Unfortunately that will not work for me, because AD locks down the environment and we cannot have anything locked down here. Ive tried copying the Admin profile over into the all users profile is system properties\advanced tab, however that overwites the programs menu and gives users programs I don’t want them to have access to. My question is…Is there a file in the All Users or Default Users profiles that allows you to set this up?
