Changing the location of the administrative installation point of office

[Natacha]

Hi there,
We are currently in the process of disabling one of our
servers, the one that has the installation point of Office
2000 on it. How do I go about to make sure that the next
time someone needs to upgrade, or re-install a feature in
office, the computer knows where to pull the files from?
Probably a registry entry to modify, but which one? Is
there an easier way to do this, considering that I would
have to go and manually change over 200 PCs?

Thanks for all your help,
Natacha
