[gptalk] Re: GPO WMI/WQL Filter

I saw that site & that query. It doesn't "universally" work, as some others have noted. Some Dell laptops return FormFactor 8, as do desktops. I personally saw this to be the case on a couple of Dell laptop models. 

The nomenclature method you helped me with will need to do.

Thx/J

If you’re using a character class like that, then yes, it is case se nsitive.
Since you’re writing filters to check whether a machine is a laptop or desktop, you might take a look at list member Jakob Heidelberg’s blog about the perfect WMI filter for this. He recently had a contes t to see who could come up with one and the winner took home a copy of SDM Software’s GPExpert Troubleshooting Pak.
Here’s Jakob’s blog: http://heidelbergit.blogspot.com/2008/02/wmi-filter-contest-are-you-knight-in. html
The winner ended up being this, which doesn’t depend on the computer name: 



(Laptop) SELECT * FROM Win32_PhysicalMemory WHERE FormFactor = 12

(Desktop) SELECT * FROM Win32_PhysicalMemory WHERE FormFactor != 12

I just tested it. That looks like it will do it. If you had any idea what I've put myself through, you would really know how thankful I am when I say thank you very much. :-)
I take it you put the lower cases in there because the query is case sensitive?

The way you are filtering on the name though, you're only saying the last character cannot be L or T. This is different than saying the last 2 characters can't be LT. 



Try this and see if it helps:



Select * From Win32_ComputerSystem Where Name Like "%[^Ll][^Tt]"

Subject: [gptalk] GPO WMI/WQL Filter



Hi everyone
I'm trying to filter a GPO using a WMI query. My goal is to have one policy only apply to desktops and one only apply to laptops. I understand that there is currently no really good method of doing this by querying hardware (and that a contest exists) :-). Fortunately, our naming standard appears to accomodate. All laptops end with "LT."
So, when I run a query for Select * From Win32_ComputerSystem Where Name Like "%LT" ---- I get the desired result when I log in to a laptop with a name ending in LT. The policy applies. When I log into a computer that does not end with LT, the GPO is filtered out and denied.
Now - to do the opposite, I'm having problems. I want to filter based on computers NOT named "%LT" - My goal in doing so is to have a policy ONLY apply to workstations (which do not end with LT in their name) --- So, I have tried: Select * From Win32_ComputerSystem Where Name Like "%[^LT]" ---- This works for me on Vista, but not on Windows XP SP2 workstations. When testing from a command prompt - on a workstation not ending with LT - I am able to validate that the "% [^LT]" exclusion is not working on XP workstations vs. it working on a Vista workstation using the following command: wmic path win32_ComputerSystem WHERE (Name like "%[^LT]") get Name.
So, it feels like I'm in the right neighborhood. I suspect that the Syntax might need to be different on XP, but I've already tried variations to no avail. 

Any help would be greatly appreciated.

Thanks

Jerry
