BOAC,
Windows XP was released in 2002, that's what the 2002 refers to.
SP3 can,
AFAIK, be slipstreamed onto any original media - RTM/Gold, SP1 or SP2.
It cannot be added to an existing XP installation without at least SP1.
This sounds like genuine media - that's what is peculiar.
Olympus, have you tried the MS forums?
