Your network consists of a single Active Directory domain. All servers run Windows Server 2003 Service Pack 2 (SP2). All client computers run Windows XP Professional Service Pack 3 (SP3).
Three client computers are public kiosks. All kiosks are configured to automatically log on as a domain user named KioskUser. KioskUser has a roaming rofile.
Users frequently change the desktop backgrounds on the kiosks.
You need to prevent changes to the desktop backgrounds from persisting when the kiosks restart.
