reinstall Office 2003 (with SP2) from a network location + active directory

[Jéjé]

Hi,

I have deployed Office 2003 by creating an installation point on my network.
then I have created a GPO in the active directory to deploy office to my end
users.

updating the installation point is simple, but how to force the
reinstallation of the client stations using the active directoy?

I have to do this:
setup.exe REINSTALL=[list of features
modified by the update] /qb
but this article don't talk about how to do it with the AD.thanks.jerome.
