SYMPTOMS

When you perform a system state backup operation on a computer that is running Windows Server 2008, Windows Vista, Windows 7 or Windows Server 2008 R2, the system state backup operation fails, and you receive the following error message:
Enumeration of the files failed.
The parameter is incorrect.
Additionally, the following event is logged in the event log on the computer:

Log Name: Application
Source: Microsoft-Windows-Backup
Date: date
Event ID: 517
Task Category: None
Level: Error
Keywords:
User: user name
Computer: computer name
Description:
Backup started at 'time' failed with following error code '2155348237' (Enumeration of the files failed.). Please rerun backup once issue is resolved.

This issue occurs if the following conditions are true:
  • There is a registry key under the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<service name>
    Note The <service name> placeholder is used for the name of the service name.
  • The value of the imagepath registry entry that is located at this subkey points to a volume that does not exist locally.
For example, assume that you perform a system state backup operation on a passive node. Additionally, assume that the imagepath registry entry of one service that is located on the passive node points to a volume that does not exist on the passive node. In this scenario, the system state backup operation fails, and you receive the error message.

Registry information

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

    Collapse this imageExpand this image
    UAC
    If you are prompted for an administrator password, type the password. If you are prompted for confirmation, provide confirmation.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SystemWriter
    Note If this registry subkey does not exist, please create it manually.
  3. On the Edit menu, point to New, and then click Multi-String Value.
  4. Type ExcludedBinaryPaths, and then press ENTER. Note
  5. Right-click ExcludedBinaryPaths, and then click Modify.
  6. In the Value data box, type all binary paths that should be excluded from the system state backup operation, and then click OK.

    Note The binary paths should be absolute paths. They should not include environment variables (such as %windir%) and should not be enclosed in double or single quoation marks.
  7. Exit Registry Editor.

Note
  • If you use this method to exclude the service data from the system state backup scope, you have to back up the service data on the shared volume manually.
  • If you assign a drive letter to a shared volume that is excluded from the system state backup scope, you have to manually re-enter all the registry keys again by using a new path because the assigned drive letter does not function any longer.
Important You have to exclude services carefully because wrong entries can corrupt the system state.

Restart requirement

You may have to restart the computer after you apply this hotfix.

Hotfix replacement information

This hotfix does not replace a previously released hotfix.

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.
  • 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.

    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.xxxxxx 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 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.
