We have a couple groups of machines, the first group are machines that
we own and the second group are leased. Both groups are running Office
2003 SP2. The second group are all created from a newer image, and the
first group are all created from an older image. Both images had
Office 2003 installed into them from a network share. When office
updates are deployed they are done via SMS. For some reason, there are
a couple Office updates for Outlook that only the first group detects
as needed, while the second group does not. This was the case with
MS07-003 and its replacement, MS08-015 (both Outlook remote code
patches).

Any idea why only the first group is detecting the update as needed?
Both groups are in the same SMS collection and recieve the same
advertisements. I am thinking it has something to do with the way
Office was installed on the images.
