For the benefit of the list, and at the risk of being repetitive.

That's not quite true.

According to Symantec you have about an 80/20% (xp/2k) chance that
offset will be used.
Though, you are right in pointing out that Server 2k3 is vulnerable as
well.

 Thanks,

This is not accurate.  For one, Windows 2000 is the only platform the
worm is spreading to, and for two, Windows Server 2003 is also impacted.
As it is no longer a trial OS, I would have expected to see it in ISS'
listing as well.  Minor, but worth noting, no less.
