An iSCSI target is not recognized as an installation target when you try to install Windows Server 2008 by using an IPv6 connection

Consider the following scenario:

• You try to install Windows Server 2008 on a computer by using an iSCSI target as the installation target.
• The computer is connected to the iSCSI target by an IPv6 connection.
• When you are prompted for the installation target, you load all the required drivers for the network adapter on the computer.

In this scenario, the iSCSI target is not recognized as an installation target. Instead, you are prompted that there is no disk available for installing Windows Server 2008.

Hotfix installation instructions

Extracting the binary files

1. Copy the hotfix file (Windows6.0-KB971443-x86.msu or Windows6.0-KB971443-x64.msu) into a folder.
2. To extract the binary files from the hotfix package, open a command prompt, switch to the directory where the hotfix file is located, and then run the following command:
   expand -f:* Windows6.0-KB971443-plaform.msu .\
   expand /f:* Windows6.0-KB971443-plaform.cab .\
   Note Replace platform with x86 or x64 as appropriate.
3. In the folder where the binary files are extracted, locate one of the following folders as appropriate for your operating system version:
   • x86_iscsi.inf_31bf3856ad364e35_6.0.6001.22458_none_3d1f5ae50ce59fda (for Windows Server 2008 x86)
   • x86_iscsi.inf_31bf3856ad364e35_6.0.6002.22159_none_3f06cd170a0b0e55 (for Windows Server 2008 Service Pack 2 x86)
   • amd64_iscsi.inf_31bf3856ad364e35_6.0.6001.22458_none_993df668c5431110 (for Windows Server 2008 x64)
   • amd64_iscsi.inf_31bf3856ad364e35_6.0.6002.22159_none_9b25689ac2687f8b (for Windows Server 2008 Service Pack 2 x64)
4. In the folder that you located in step 3, find the Msiscsi.sys file.

Creating valid DVD installation media

Before you follow these steps, visit the following Microsoft Web site to install the Windows Automated Installation Kit (AIK):
Download the Windows Automated Installation Kit (AIK) package now.

1. Create a temporary folder, such as D:\temp.
2. Create the following two subfolders in the Temp folder:
   1. Win2008Copy
   2. Win2008Mod
3. Copy all the contents from the DVD installation media into the Win2008Copy folder.
4. Open the Windows AIK command prompt in elevated mode, and then run the following commands:
   attrib -r .\Win2008Copy\sources\install.wim
   attrib -r .\Win2008Copy\sources\boot.wim
5. Run the following command to mount the Install.wim image:
   imagex /mountrw .\Win2008Copy\sources\Install.wim X .\Win2008Mod
   Note Replace the X placeholder with the image number (1 for Standard Server systems, 2 for Enterprise Server systems, 3 for DataCenter Server systems, and other corresponding image numbers).
6. The Install.wim image was mounted in the Win2008Mod folder. Find the Msiscsi.sys files in the subfolders of the Win2008Mod folder, and then replace these files with the Msiscsi.sys file that you extracted from the hotfix package. To easily find all the Msiscsi.sys files to be replaced, run the following command:
   dir /s .\Win2008Mod\MSiSCSI.sys
7. Run the following command to unmount the Install.wim image:
   imagex /unmount /commit .\Win2008Mod
8. Run the following command to mount the Boot.wim image:
   imagex /mountrw .\Win2008Copy\sources\Boot.wim X .\Win2008Mod
   Note Replace the X placeholder with the image number that you specified in step 5.
9. The Boot.wim image was mounted in the Win2008Mod folder. Find the Msiscsi.sys files in the subfolders of the Win2008Mod folder, and then replace these files with the Msiscsi.sys file that you extracted from the hotfix package. To easily find all the Msiscsi.sys files to be replaced, run the following command:
   dir /s .\Win2008Mod\MSiSCSI.sys
10. Run the following command to unmount the Boot.wim image:
    imagex /unmount /commit .\Win2008Mod
11. Run the following command to create an .iso file:
    OSCDimg.exe /m /nt /b"C:\Program Files\Windows AIK\Tools\PETools\platform\boot\etfsboot.com" .\Win2008Copy Win2008Mod.iso
    Note The platform placeholder represents the architecture of the operating system to be installed, such as amd64 or x86.
12. Burn the Win2008Mod.iso file to a DVD by using a DVD-burning application.
13. Perform the installation by using the new DVD.
