It's amazing how once you've seen WMI script you see it, or rather you
think you see it, all over the place. Must check out the F2003 CD to see if
there's any of it lurking therein.
I had a word with my Johnny Fever guy (SysOP) earlier today who brought
this C# WMI app to my attention:
http://www.codeproject.com/csharp/wmi.asp?target=wmi
He tells me that WMI is favored in .NET over dealing directly with the API.
It looks interesting.
