User files are available offline when SMB shares don't allow client caching in Windows 7 or Windows Server 2008 R2

Symptoms
This issue occurs when the following conditions are true:
  • You have a network-attached storage device that supports Server Message Block (SMB) protocol version 2.1 and contains a shared folder.
  • You connect to the NAS shared folder by using a Universal Naming Convention (UNC) path, such as \\ServerName\ShareFolder, and you access a file from a computer that's running Windows 7 or Windows Server 2008 R2.
  • You have disabled the offline files feature on the share and cleared Always offline available in Sync Center.

If the network-attached storage device is turned off, you don't receive error messages when you try to access files on the share. Files that you previously accessed are pinned offline, and are available through client-side caching in Sync Center.
Resolution
To fix this issue, we have released a hotfix for Windows 7 and Windows Server 2008 R2.

File information

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).

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 and 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's 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, milestone (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 1.17xxxWindows 7 and Windows Server 2008 R2SP1GDR
  • 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" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes aren't listed, are signed with a Microsoft digital signature.
