Was the CD you tried to use just the SP2 service pack or the XP
operating system with the SP2 service pack? It sounds like you tried to
use the latter.

You should be able to install the SP2 kit via Windows Update from here:
http://go.microsoft.com/?linkid=3646727
or download it from here:
http://go.microsoft.com/fwlink/?linkid=23354
and install it later.
