WMI Namespaces - Is There An 'Official List'?

Question

I'm (unfortunately) venturing into Windows (XP) scripting and WMI (Windows Management Instrumentation) as I am attempting to write scripts that will configure such things as network adapters, users etc.

Key to this seems to be the so-called WMI 'Namespaces'; once one has the name spaces apparently it's possible to discover classes within the namespace and read/alter data as necessary. (Apologies if I have misunderstood anything about WMI & namespaces).

So the obvious question is, just what WMI namespaces are available? It's fine being able to write a script that lists them but where is the official Microsoft list of namespaces? How on earth are you supposed to know what:

1. Namespaces official exist?
2. What classes are under each namespace?
3. Where do I look for a specific class say for network settings?

Answer 1

I created the list, you can see it at http://wutils.com/wmi/namespaces.html. It is not official list, of course. It contains list of namespaces in plain installation of Windows server with some extensions (sql server, exchange) and list of classes/properties/methods in each of the namespace.
