You cannot read the GPO in the SYSVOL directory in Windows 7 or in Windows Server 2008 R2 if you enable the "Deny write" permission of the GPO

Symptoms

Consider the following scenario:

  • You open the Group Policy Management Console (GPMC) Microsoft Management Console (MMC) snap-in on a computer that is running Windows 7 or Windows Server 2008 R2.

  • You connect to a domain controller by using the GPMC MMC snap-in.

  • You enable the Deny write permission of a Group Policy object (GPO) for a user account.

  • You use this user account to log on to the computer.

In this scenario, the user account cannot read the GPO in the SYSVOL directory. Therefore, the user account cannot apply the settings of the GPO.

If you use Windows Explorer to access the GPO-related folder in the SYSVOL directory, you receive an error message that resembles the following:

Windows cannot access <folder path>
Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve the network problem, click Diagnose.



Cause

This issue occurs because the GPMC snap-in incorrectly denies read access to the GPO in the SYSVOL directory when the GPMC denies write access to the GPO.

Resolution

To resolve this issue, this hotfix must be installed on all operating systems that have GPO edits authorized. Performing GPO modification on an un-patched system re-introduces the problem. This also applies to mixed mode domains. GPO modification from Windows 2008 also re-introduces the problems. This hotfix is available only for Windows Server 2008 R2.

Windows 7 and Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
