SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows Server 2008 or Windows Vista.
  • You try to access earlier versions of shared files that are hosted on a remote file server.
In this scenario, you receive a Stop error message that resembles the following:
STOP 0x00000027 (parameter1, parameter2, parameter3, parameter4)
The RDR_FILE_SYSTEM
Notes
  • The parameters in this error message vary, depending on the configuration of the computer.
  • Not all "0x00000027" Stop errors are caused by this issue.

CAUSE

This issue occurs because of an error in the Windows client-side caching driver (Csc.sys).

When Csc.sys compares strings in a file path, Csc.sys handles uppercase and lowercase characters incorrectly. Therefore, the operating system accesses an uninitialized variable, and you receive the Stop error message that is mentioned in the "Symptoms" section.

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.

    VersionProductSR_LevelService branch
    6.0.600 1 . 22xxxWindows Vista and Windows Server 2008SP1LDR
    6.0.600 2 . 22xxxWindows Vista and Windows Server 2008SP2LDR
  • 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.
