I have installed SP2 :
with orriginal install disks
with the sp2 patch cdrom
with the download and install later
via windows update
via SUS
and via WSUS
with no problems on any of my desktops or laptops at work or at home.
a freash install with an orriginal install sp2 CD should be no problem

When you did the initial install, did the problem exist or was it only after doing all of the patches? are you doing an express update or a compleat update? if express, i would run the other just to be sure.
