Symptoms

Consider the following scenario:
  • You have a shared folder on a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1.
  • A user (user A) maps a network drive to the shared folder. Therefore, user A can receive change notifications from the shared folder.
  • Another user (user B) changes a file in a subfolder or adds a file to a subfolder that user A does not have permission to access. The subfolder is in the shared folder.
In this scenario, user A receives Server Message Block (SMB) change notifications from the subfolder.

Notes
  • The expected behavior is that user A does not receive change notifications from the subfolder.
  • Change notifications are sent when any of the following activities occur:
    • A user creates files or folders.
    • A user changes existing files or folders.
    • A user reads the documents that are temporarily written to the shared folder or automatically saved or locked in the shared folder.

Cause

This issue occurs because the SMB protocol cannot modify change notification requests for each user.

Resolution

The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.
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 files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    VersionProductMilestoneService branch
    6.1.760 1.18xxxWindows 7 and Windows Server 2008 R2SP1GDR
    6.1.760 1.22xxxWindows 7 and Windows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • 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 7 and for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
