RESOLUTION

To resolve this problem, install the hotfix that is described in this article, and then configure a new registry option that is named NeedsSystemShutdownNotification. This new registry option controls whether a particular SCSI adaptor must be sent a stop request while the system is shutting down. For information about how to add and to configure the registry option, see the "More Information" section.

Note Computers that are running Windows Server 2003 do not need to apply this hotfix because the registry key is supported natively. To enable this fix for Windows Server 2003, follow the steps in the "More Information" section.

MORE INFORMATION

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To configure the new registry option, add a DWORD that is named NeedsSystemShutdownNotification and that has a value of 1 to the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Bus\deviceId\device\Device Parameters\ScsiPort
Note You must select the correct subkeys for Bus, deviceId, and device. For example, for a PCI bus device, you might add a DWORD that is named NeedsSystemShutdownNotification and that has a value of 1 to a registry subkey that is similar to the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1039&DEV_0001&SUBSYS_00000000&REV_00\3&61aaa01&0&08\Device Parameters\ScsiPort
To configure the new registry option, follow these steps:
  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Bus\deviceId\device\Device Parameters\ScsiPort

    Note If the ScsiPort subkey does not exist, you must create it. To do this, follow these steps:
    1. Locate and then click the following subkey in the registry:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Bus\deviceId\device\Device Parameters
    2. On the Edit menu, point to New, and then click Key.
    3. Type ScsiPort for the name of the subkey, and then press ENTER.
    4. Click the ScsiPort subkey.
  3. On the Edit menu, point to New, and then click DWORD Value.
  4. Type NeedsSystemShutdownNotification for the name of the DWORD, and then press ENTER.
  5. Right-click NeedsSystemShutdownNotification, and then click Modify.
  6. In the Value data box, type 1, and then click OK.
  7. Quit Registry Editor.
Note To configure the adaptor driver to use the value, modify the .inf file for the adaptor driver with information that is similar to the following: 
 
       [install_section_name.HW]
      HKR, “ScsiPort”, “NeedsSystemShutdownNotification”, 0x00010001, 1
For more information about how to configure the adaptor driver, see the latest version of the Microsoft Windows Driver Development Kit (DDK) documentation. For additional information about the DDK, visit the following Microsoft Web page:
