"0x0000007B" Stop error after you replace an identical iSCSI network adapter in Windows Server 2008 R2 SP1 or in Windows 7 SP1

SYMPTOMS
Consider the following scenario:
  • You have a computer that is running Windows Server 2008 R2 Service Pack 1 (SP1) or Windows 7 Service Pack 1 (SP1). The computer supports PCI Express Serial Number Capability.
  • You configure the computer to start from an iSCSI disk.
  • You use an identical device to replace the iSCSI network adapter. For example, the network adapter is a separate network adapter card, or the network adapter is a built-in device on a motherboard.

    For example, you replace the device because of a hardware failure.
  • You log on to the computer, and then you restart the computer.
In this scenario, you receive the following Stop error message:
STOP 0x0000007B ( parameter1, parameter2, parameter3, parameter4 ) INACCESSIBLE_BOOT_DEVICE
Notes
  • The four parameters in this Stop error message may vary, depending on the configuration of the computer.
  • Not all "0x0000007B" Stop error messages are caused by this issue.
  • A similar issue occurs on computers that are running Windows Server 2008 or Windows Vista. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
    2487376 FIX: Stop error when you replace an iSCSI network adapter or a motherboard by using an identical device on a Windows Server 2008-based or Windows Vista-based computer: "0x0000007B"

  • Note the replacement network adapter must be placed in the same slot as the original network adapter.
  • After applying this hotfix, even when you replace the device with the PCI Express device holding a different serial number, the device instance path would not be modified as long as the same device model is connected to the same slot. In this case, the same device instance path, which is stored in the registry, would continue to be used. Thus, the reinstallation of the device does not occur.
  • Note that if the failed iSCSI network adapter is a built-in device, and you choose to use a different built-in adapter for iSCSI boot, that installing this hotfix will not resolve the issue, because the adapter would not be in the same PCI-Express location. You would need to manually unbind the Light Weight Filter (LWF) from the second network adapter. See the following KBs for more details: KB2507616, KB976042
CAUSE
This issue occurs because Windows recognizes the network adapter or the motherboard as a new device.

When the serial number of the network adapter or of the motherboard differs from the serial number of the previous network adapter or motherboard, Windows recognizes a new device.

Windows 7 and Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" 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, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    VersionProductMilestoneService branch
    6.1.760 0.16xxxWindows 7 and Windows Server 2008 R2RTMGDR
    6.1.760 0.20xxxWindows 7 and Windows Server 2008 R2RTMLDR

    6.1.760 1.21xxxWindows 7 and Windows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • 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 7 and for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical 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.
