Would it not be $Longhorn$ ?? It's just a guess but it would make sense.

Stick with 2003, unless you're planning on going to Vista then 2008 really doesn't offer you anything other than price as a benefit. You may also find you have issues if you have non standard applications (just ask my Applications Architect who is pulling his hair out over com+ compatibility).

Go to Guru3d.com and download Driver Cleaner, uninstall the current drivers, boot into safe mode, run Driver Cleaner, reboot into normal and install the new drivers.

Generally speaking it's because the WAIK and the Image it's trying to open aren't compatible, I had the same when I tried to open an SP1 image on the older version of the WAIK. Are you sure that you downloaded the newer WAIK rather than the older one Windows AIK for Windows Server 2008 and Windows Vista Service Pack 1 (x86, x64, ia64) - DVD (English)en_windows_automated_installation_kit_1.1_x86_x64_ia64_dvd_71832.iso size = 1,196.10mb date = 2008-04-01 Windows Automated Installation Kit (WAIK) - DVD (English)en_windows_vista_windows_automated_installation_kit_dvd_X13-63415.iso size = 992.16mb Date = 2007-05-07

There are various reg file tweaks that can be applied to a build once it's been installed. One thing I would be concerned about is the lack of AV software, obviously WoW is still a highly targeted product and just reinstalling the OS won't save you if it's the WoW installation that's infected (also run the risk of infecting the main partition when you get that up and running).
