Symptoms

Consider the following scenario:

  • You have a computer that is running one of the following operating systems:

    • Windows Vista
    • Windows Server 2008
    • Windows 7
    • Windows Server 2008 R2

  • You set up an iSCSI storage device on the computer. Then, you configure the persistent logon setting and Challenge Handshake Authentication Protocol (CHAP) authentication setting for the device.

  • You disconnect the network connection on the computer, and then you restart the computer.

  • You wait at least 30 seconds, and then you reestablish the network connection.

  • The iSCSI initiator user interface displays the connection state as Reconnecting.

In this scenario, the iscsicpl.exe process stops responding. Additionally, you cannot disconnect the storage device from the computer. To reestablish the connection between the storage device and the computer, you must restart the computer.

Cause

This issue occurs because the session between the storage device and the computer is locked when the iSCSI initiator tries to log on. However, the iSCSI initiator does not try to log on after 10 failed log on attempts. Therefore, the session is not released.

Windows Vista and Windows Server 2008 file information notes

Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" 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, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    Version Product SR_Level Service branch
    6.0.600
    2.
    22xxx    		 Windows Vista and Windows Server 2008 SP2 LDR

  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.

  • 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 Server 2008 and for Windows Vista" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important 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.

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:

    Version Product Milestone Service branch
    6.1.760
    0.16xxx    		 Windows 7 and Windows Server 2008 R2 RTM GDR
    6.1.760
    0.21xxx    		 Windows 7 and Windows Server 2008 R2 RTM LDR

    6.1.760
    1.21xxx    		 Windows 7 and Windows Server 2008 R2 SP1 LDR

  • 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 Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important 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.
