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]” 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 4:56 PM To: gptalk@xxxxxxxxxxxxx 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.
