RIS delivers only clean installs of XP Professional, you cannot use this technology to upgrade clients such as Windows 98 to XP. While you cannot use RIS to install domain controllers, you can have Windows Server 2003 stand alone servers which can then join the domain and promoted to domain controllers. Wireless networks do not support PXE network cards, so you cannot use the wireless medium to install XP Professional via RIS.
