SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows Server 2008 or Windows Vista.
  • You create a mount point on a volume that uses the NTFS file system on this computer.
  • You create a junction point to the location of this mount point on the volume.
  • You share the root folder of this volume.
  • You access files and folders that are located at the mount point by using this shared root folder from one of the following computers:
    • A computer that is running Windows Server 2003 or Windows XP.
    • A computer that is running Windows Server 2008 or Windows Vista if the Server Message Block (SMB) 2.0 protocol is disabled on the computer.
In this scenario, you cannot access files and folders on the volume by using the junction point, and you receive the following error message:
<Share_Path> is not accessable. You might not have permissions to use this network resource. Contact the Administrator of this server to find out if you have access permissions. The data present in the reparse point buffer is invalid.
Note You can access these same files and folders by using the mount point.

CAUSE

This problem occurs because the SMB file system driver (Srv.sys) handles multiple reparse points across a share incorrectly.

Windows Vista and Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxx version number.
  • 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 and for Windows Vista" section. MUM files 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.
