GPO: WMI Filtering

Fun with WMI Filters in Group Policy

Interesting comments:
..do they add more significant load on domain controllers..?
This should add no real load to the DC's, as the WMI processing happens client-side. Although it might make GP processing take just a bit longer on the client, and that would have the client talking to DC a bit longer, so I suppose in that sense there
might be some tangental load... probably not measurable. :)

..I need to filter out a Windows 2008 64 bit server, that is not a DC from everything else. I have this so far, but somehow my Vista clients still get it, which I really dont want to.
Just do Start, Run, WBEMTEST. Then click Connect, leave it as root\cimv2, then click Query, and paste in your query as-is, then click Apply. If you get 0 objects returned that is a False, 1 object returned is a True.
