Any ADMX/ADM setting is processed by the (what you call default) Registry CSE. I have not seen a list since GPP was released, but there might be one out there. If no one knows of a list, a (somewhat time consuming) way to find out is to have a new GPO, use the Active Directory Explorer, ADSIEdit or another LDAP tool to check the value gPCMachineExtensionNames or gPCUserExtensionNames (depending if you are changing the user or computer part) of the GPO before and after you do a setting you want to figure out what CSE is used to processes. Compare the new GUID added with the ones you can find in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions, do it at a computer where you have GPP installed and the default registry key will tell you the name of the CSE. You find the GPO objects in the CN=System, CN=Policies path of your domain, each with a CN that matches the one you can see in GPMC as Unique ID. Also the value you find in gPCMachineExtensionNames and gPCUserExtensionNames comes in pairs within brackets, it is the first one you are interested in, the second one is the GPO MMC snap-in that was used to edit the GPO. So with this knowledge on how to figure it out added to the GP community perhaps someone will create the full list :) HTH, Thorbjörn Sjövold Special Operations Software www.specopssoft.com<http://www.specopssoft.com> thorbjorn.sjovold a t specopssoft.com Download our free tool for remote Gpupdate with graphical reporting, http://www.specopssoft.com/products/specopsgpupdate/ From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Hendrikus Terwint (SEDIRSI-Prestataire) Sent: den 16 april 2008 15:39 To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Complete list of all available CSEs and their functionality Hello everybody, Is there a way to determine which GP setting is processed by which CSE ? I have found a list of default Client-Side Extensions on Technet: http://technet2.microsoft.com/windowsserver/en/library/824b4758-9430-4633-8d8f-3dad0f2bf8391033.mspx?mfr=true However, I'd like to see a complete list, just like the "Group Policy Settings Reference" on windows.com/downloads, with a column that says which CSE is responsible for processing which setting. For example: if we use the DFS.admx to change the DFS network policy. Is there a DFS CSE that processes this policy, or is it processed by one of the default CSEs? Does it require an extension at all? Maybe the CSE list on the link above is quite complete, and all other settings are processed by the Group Policy Engine itself? Is there such list around somewhere? (that links every possible GP setting to the GP Engine or CSE component that processes this setting) Many thanks in advance, Hendrikus TERWINT Consultant Avanade France hendrikus.terwint@xxxxxxxxxxx<mailto:hendrikus.terwint@xxxxxxxxxxx> Prestataire pour le compte de SEDI-RSI, site de Bagnolet Tél. : 01 55 82 39 70
