An ACPI APIC UP HAL operating system image cannot be deployed if a Windows Vista boot image or a Windows Server 2008 boot image is used in the deployment process

Consider the following scenario:

• You install the Windows Deployment Services (WDS) server role on a computer that is running Windows Server 2008 R2, Windows Server 2008, or Windows Server 2003.
• In the local area network (LAN), you use a Windows Vista boot image or a Windows Server 2008 boot image to deploy one or more operating system images in Windows Deployment Services.
  Note This problem does not occur if you use a Windows Vista Service Pack 2 (SP2) boot image or a Windows Server 2008 Service Pack 2 (SP2) boot image.
• You try to deploy an image that is based on an ACPI Uniprocessor (ACPI APIC UP) Hardware Abstraction Layer (HAL) to a client that uses an ACPI APIC UP HAL or an ACPI Multiprocessor (ACPI APIC MP) HAL.

In this scenario, the image is not displayed in the menu for the available operating system images during the deployment process. Therefore, you cannot deploy the image to the client.

Note This problem also occurs in Windows 7 boot images and in Windows Server 2008 R2 boot images. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

The issue occurs because the Wdsclient.dll module incorrectly excludes images that are based on an ACPI APIC UP HAL when the Wdsclient.dll module displays the menu of the available operating system images.

For the x86-based Windows Vista boot image and for the x86-based Windows Server 2008 boot image

For the x64-based Windows Vista boot image and for the x64-based Windows Server 2008 boot image

For the IA-64-based Windows Server 2008 boot image

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

You must apply this hotfix to the second image of the Windows Vista or Windows Server 2008 boot image file. To do this, follow these steps.

Note The second image is the Windows Preinstallation Environment (Windows PE) image.

1. On the Windows Deployment Services server, install the Windows Automated Installation Kit (AIK) for Windows 7.
   To obtain the Windows AIK for Windows 7, visit the following Microsoft website:http://www.microsoft.com/downloads/details.aspx?familyid=696DD665-9F76-4177-A811-39C26D3B3B34&displaylang=en

   Note You can also install Windows AIK for Windows 7 on a separate computer that is running an operating system that is supported by Windows AIK for Windows 7.
2. Click Start
   Collapse this imageExpand this image

   
   , click All Programs, click Microsoft Windows AIK, right-click the Deployment Tools Command Prompt, and then select Run as administrator.

   If you are prompted for an administrator password or for confirmation, type the password, or provide confirmation.
3. Extract the Windows6.0-KB935772-Platform.cab file from the hotfix package to a temporary folder. To do this, follow these steps:
   1. Click Start
      Collapse this imageExpand this image

      
      , click Run, type cmd, and then click OK.
   2. At the command prompt, type the following command, and then press ENTER:
      Expand.exe CabFilePath -R -F:* TempFolderPath
      Notes
      • The CabFilePath placeholder represents the path of the CAB file.
      • The TempFolderPath placeholder represents the path of the temporary folder.
4. Disable the problematic boot image to make it unavailable for download in the update process. To do this, open the Windows Deployment Services Microsoft Management Console (MMC) snap-in, right-click the boot image that you want to update, and then select Disable.
5. Export the problematic boot image from the Windows Deployment Services server to BootWimPath. To do this, right-click the boot image, and then select Export Image. Export the boot image to BootWimPath.
   
   Notes
   • The BootWimPath placeholder represents the local directory where the Boot.wim file is exported.
   • If you install the Windows AIK on a separate computer, you must copy the Boot.wim file to a directory on that computer. Then, perform step 6 through step 8 on that computer.
6. Mount the boot image for read access and for write access. To do this, type the following command at the command prompt, and then press ENTER:
   dism /mount-wim /wimfile:BootWimPath /index:2 /mountdir:MountLocation
   Note
   • The MountLocation placeholder represents the location to mount the image.
   • Make sure that you mount the image whose boot index number is 2.
7. Copy the Wdsclient.dll file from the TempFolderPath folder to the following folders:
   • MountLocation\sources
8. Unmount the Boot.wim file, and then commit all changes. To do this, type the following command at the command prompt, and then press ENTER:
   Dism.exe /unmount-wim /mountdir:MountLocation /commit
9. Add the updated Boot.wim file back to the Windows Deployment Services server. To do this, open the Windows Deployment Services MMC snap-in, right-click Boot Images, select Add Boot Image, and then specify the path to the updated Boot.wim file
10. In the Windows Deployment Services MMC snap-in, right-click the boot image that you added to make sure that it is enabled.
    
    Note You have to disable or delete the problematic boot image.
