Not sure if this should be in Office or Windows, but I"ll start here
We are reasearching ways to update our Office installs that were done from an administrative install. Microsoft's articles, such as: http://www.microsoft.com/office/ork/updates/oxppatchadmin.htm
say that if we deployed Office through a GPO, then we could apply the update to the administrative install, and then through the GPO, redeploy the update.
In the article I posted it says, " The next time the Group Policy Object is applied to the designated users or computers, the updated files are copied to their computers."
Does Microsoft mean this literally and it will only copy the truly updated file or will it do a complete reinstall? Bandwidth is an issue here and I would want to keep it to a minimum and if I read this correctly, it sounds like it would, but I want to see if anyone knows for sure.
A second part of this question, or a whole new question of the situation calls, would relate to the next line in the Microsoft article: Note You can redeploy a package only if it is being managed by Group Policy — that is, only if you originally installed it by using IntelliMirror software installation and maintenance or if you brought it into a managed state under Windows 2000.
How do you bring an existing Office install through an administrative point into a managed state via Group Policy without doing a complete reinstall? I can make this a whole new question if you think I should.
