Doug's points are well taken here. Using File System Security policy is DANGEROUS when you're operating on the root of a volume. This is why I tend to just prefer using something like cacls.exe instead of GP. Cacls lets you append permissions, whereas GP is not as flexible. And since you only need to do this once, GP's periodic refresh feature is probably overkill. _____ From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Delaney, Doug Sent: Wednesday, September 20, 2006 10:18 AM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Re: drive access I would add the %SystemDrive% to the File System entries, under Computer Configuration | Windows Settings | Security Settings | File System and configure the (Advanced) permissions for the user group required (my example user the "Users" built-in group). Ensure you select This folder only in the apply onto field, and deny creating files and folders. Also ensure that you configure all other security settings required (to match what they are locally) as this will replace the existing permissions with a new set of permissions... so be VERY careful w/regard to inheritance. This means you be replacing the entire set of permissions on drive C: so will will have to add an addition entry for Users (in my example) that apply onto is set to "subfolders and files only". When you click ok, then click on Configure this file or folder then, select replace permissions on all subfolders and files. Please ensure you include ALL other groups currently defined on Drive C... Everywhere, paying special attention to Program Files, Documents and Settings, and the %SystemRoot% folders. AGAIN, you are replacing ALL security settings on drive C: using this method. But, it gives you complete and granular control. You also want to TEST using only one entry for users at the root of C:, and see if that does or does not replace all lower permissions (subfolders) if you select propagate inheritable permissions on all subfolders and files (instead of replace), but I have not had the expected results using that in the past.

I have told the group policy not to allow saving of files to c however if you creat a new folder you can save to that folder. Anyone know how to stop this?
