We are running Zen 6.5. We want to start using XP sp2 but need to update
the group policies that are in ZEN. With Windows XP and AD, all we needed
to do was to have XP SP2 installed on a machine and run Group Policy
Management Console and the additional 600+ setting were populated.

How do we get those into the ZEN group policy?

I have opened the group policy to see if they populate, but they do not.
