SYMPTOMS

Consider the following scenario. You try to deploy Windows Vista by using Windows Deployment Services (WDS) in an Active Domain environment. You have configured the new client naming policy for WDS. To make every client name unique, the automatic naming options apply an increasing number in every new client name. For example, you use %[0][n]# as the expression for the new client naming policy.

In this scenario, WDS cannot generate more than 255 client names. Therefore, you cannot add more than 255 machine account objects (MAO) into the domain. Users can install Windows Vista on more than 255 client computers. However, only the first 255 computers are automatically joined to the domain. Therefore, you cannot centrally manage the Windows Vista deployment for other computers.

CAUSE

This problem occurs because of a hard-coded limitation in the Wdsclient.dll file.

Hotfix installation information

To apply the hotfix that is mentioned in this article, follow these steps:
  1. The hotfix that is mentioned in this article contains a CAB package. Extract the Wdsclient.dll file from the CAB package to a temporary folder. To do this, double-click the CAB package.
  2. Install Windows Automated Installation Kit (Windows AIK) or Windows OEM Preinstall Kit (Windows OPK).
  3. Disable the boot image on the WDS server to make the boot image unavailable for downloading. For example, you can run the following command at a command prompt:
    wdsutil.exe /set-image /image:<ImageName> /imagetype:boot /architecture:<Platform> /enabled:no
    Note The <ImageName> placeholder represents the name of the boot image. Replace the <Platform> placeholder with x86, with x64, or with ia64, as appropriate for your situation.
  4. Export the boot image from the WDS server. For example, you can run the following command at the command prompt:
    wdsutil.exe /export-image /image:<ImageName> /imagetype:boot /architecture:<Platform> /destinationimage /filepath:<PathToBootWIM>
    Note The <ImageName> placeholder represents the name of the boot image. Replace the <Platform> placeholder with x86, with x64, or with ia64, as appropriate for your situation. The <PathToBootWIM> placeholder represents the Windows Imaging Format (WIM) file to which you want to export the boot image.
  5. Mount the boot image that you exported in step 4. When you do this, specify an index of 2, and specify read access and write access. For example, you can run the following command at the command prompt:
    imagex.exe /mountrw <PathToBootWIM> 2 <MountLocation>
    Note The <PathToBootWIM> placeholder represents the location where you exported the boot image in step 4. The <MountLocation> placeholder represents the location where you want to mount the boot image. For more information about this operation, see the documentation that is provided in the Windows OPK.
  6. Locate the Wdsclient.dll file that you extracted in step 1. Copy the Wdsclient.dll file to the Sources folder in the mount location that you specified in step 5, and replace the existing file.
  7. Unmount the WIM file that you specified in step 5 by committing all changes. For example, you can run the following command at the command prompt:
    imagex.exe /commit /unmount <MountLocation>
    Note The <MountLocation> placeholder represents the mount location that you specified in step 5.
  8. Add the WIM file back to the WDS server. For example, you can run the following command at the command prompt:
    wdsutil.exe /replace-image /image:<ImageName> /imagetype:boot /architecture:<Platform> /replacementimage /imagefile:<PathToBootWIM>
    Note The <ImageName> placeholder represents the name of the boot image that you want to specify. Replace the <Platform> placeholder with x86, with x64, or with ia64, as appropriate for your situation. The <PathToBootWIM> placeholder represents the WIM file that you specified in step 5.
  9. Delete all temporary folders.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Vista Service Pack 1.
