If you’re using a character class like that, then yes, it is case sensitive. 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 contest 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 Regards, Jamie Nelson | Operations Consultant | BI&T Infrastructure-Intel | Devon Energy Corporation | Work: 405.552.8054 | Mobile: 405.200.8088 | http://www.dvn.com <http://www.dvn.com/> From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Jerry Abouelnasr Sent: Thursday, October 23, 2008 5:15 PM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Re: GPO WMI/WQL Filter 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?

This is different than saying the last 2 characters can't be LT.

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.
