I know the “classic” GPO WMI filtering did not support Array type, so it was not possible to use the Win32_SystemEnclosure.ChassisTypes to determine if a computer was a desktop or a laptop.



Recently I tried to use a similar approach with GPP Item-Level Targeting WMI but surprisingly it does not work either. L



I strated creating a write-registry GPP with the following targeting:

- He portable computer docking state is docked, undocked, unknown

- OR a battery is present

- OR a PCMCIA is present

and the registry key got written to my laptop (Win 7).



I started adding the following and had no luck:

OR SELECT ChassisTypes from Win32_SystemEnclosure WHERE (ChassisTypes="8" OR ChassisTypes="9" OR ChassisTypes="10" OR ChassisTypes="11" OR ChassisTypes="14" OR ChassisTypes="18")



I tried a simpler query and no luck either:

OR SELECT ChassisTypes from Win32_SystemEnclosure WHERE ChassisTypes="8"



On the other hand I tried a different query that is not an Array type and works:

SELECT PCSystemType FROM Win32_ComputerSystem WHERE PCSystemType="2"



So my question… does really GGP *NOT* support WMI Query for Array types?



Thanks – Gabriele.

No, it doesn’t work. You can track why through the following posts:

Have a read of this article. http://www.heidelbergit.dk/2008/02/wmi-filter-contest-are-you-knight-in.html



I use this and it seems to work well for the most part:



Laptops: Select * from Win32_PhysicalMemory where FormFactor = 12

Desktops: Select * from Win32_PhysicalMemory where FormFactor != 12



But there is no perfect solution that will suite everyone’s needs, and the above query is not 100% bullet proof.



In my large deployments, I stamp the registry with info, create a MOF file and use MOFCOMP.exe to register it. I blogged about it here: http://www.jhouseconsulting.com/2009/05/10/using-a-group-policy-wmi-filter-to-test-for-a-registry-value-290



What you could do is run a build/startup script that populates a registry key with the output of a Win32_SystemEnclosure.ChassisTypes query and then use my method to read it. It’s a bit convoluted, but will provide the solution you’re looking for. In fact, this has just given me some ideas J



Cheers,

Jeremy.

Gabriele-

Based on the silence, I’m going to assume no one knows the definitive answer to this. J. I will see if I can get an answer from the GP product team or will try to test this myself if I can.
