Explanation:
If you need to configure a Remote Desktop Server farm and need to setup some group policies that only applied to computers that are Remote Desktop Servers, there are a couple of obvious ways you could achieve this. 1) You could put your Remote Desktop Servers in a specific Organizational Unit and link your Group Policies there
2) You could create a WMI Filter to filter by name i.e.
SELECT * FROM Win32_ComputerSystem WHERE ((Name = 'RDSERVER01') OR
(Name = 'RDSERVER02'))
If you don't want to have to update the WMI Filter if you need to add more Remote Desktop Servers, you can use the following WMI Filter against the rootCIMV2TerminalServices Namespace:
Select * From Win32_TerminalServiceSetting Where TerminalServerMode=1
