The registry contains that info for the currently logged-in user only. Our requirement is for the script to walk the domain (or a selected OU) and interrogate each machine for its installed software, including what's been pushed out by GP. For locally installed software, we'll kick off a remote removal. For GPO-pushed stuff, all we can do is determine if user is a member of the group assocaited with the GPO. This latter requirement is why we need to find out which group is filtered on the GPO. Anyway, I've arrived at a solution: - query the AD for the ProductCode and get the container name(s), plural because there may be AD orphans containing the code. I'm researching a method to determine which GPO is the 'live' one. - parse that container name for the GPO's container name (is there a 'method' to get that? I'm just looking for '{' then '}' and using what's in between!) - get the SecurityDescriptor details for the GPO - test if the trustee name returned is a group and, if so, add it to a dictionary - loop through the dictionary and test the account's membership of that group. It's a mess at the moment but at least I know I can get the info I need. Now all I need to do is shoe-horn my QAD script into the actual script which will do the work. ________________________________ From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Darren Mar-Elia Sent: 02 October 2008 16:29 To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Re: Determining group associated with a GPO If all you know is the product code, you will need to query every packageRegistration object in AD to look for that product code, and then from there you can derive the GPO name/id. But I wonder if you really have to do that. I seem to remember that somewhere in the registry metadata on the client that you can make the link between product code and GPO. You should investigate that before going down the path of querying AD. I would check for you if I had a machine with a deployed package handy.

I realise my error now. I actually don't know the GPO name (nor therefore its ID). So, to re-phrase my question: If I know the ProductCode (in all its forms) what query can I use to get the group associated with the GPO containing that ProductCode? I appreciate that there may be duplicate records but I can handle that as a separate issue.

You can use the GPMC APIs to query the security on a GPO. This makes it very easy to get at that info. Let me know if that did not answer your question. Darren From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Northwood, Ian Sent: Thursday, October 02, 2008 7:34 AM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Determining group associated with a GPO Folks, As part of a licensing audit, I have been asked to build a script to interrogate installed software on machines. Easy enough. However, we want to be able to determine which apps were installed per-user by Group Policy and whether the user concerned is in the group associated with the package. How do I query AD to determine the group associated with the GPO, given that I know: - all the users who have had software pushed to them having logged into the machine (I loop through 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Managed\[User's SIDs]\Installer\Products\[PackedProductCode]) - the GPO name and its GUID - the ProductCode, its packed form and its octet/byte array form The idea is that we produce a list of accounts who appear in the registry as having had 'Package X' installed but who are not in the associated group.
