Windows 2008 Server Manager Roles Summary error 0x800B0100


  • Hello!

    On our Windows 2008 Server Standard SP2 32bit machine when opening
    Server Manager Roles Summary I got an error with HRESULT 0x800B0100

    In the Event Viewer log (in Applications and Service logs, Microsoft, Windows, ServerManager, Operational log) the following error is logged
    (I am translating from the italian version on Windows server, maybe some words could be different in the real english versions)
    Cannot find system state. Exception
    System.Runtime.InteropServices.COMException (0x800B0100): No signature found in the subject. (Eccezione da HRESULT: 0x800B0100)

    The original message in Italian language
    Impossibile individuare lo stato del sistema. Eccezione imprevista:
    System.Runtime.InteropServices.COMException (0x800B0100): Nessuna firma trovata nel soggetto. (Eccezione da HRESULT: 0x800B0100)
       in System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)
       in Microsoft.Windows.ServerManager.ComponentInstaller.CreateSessionAndPackage(IntPtr& session, IntPtr& package)
       in Microsoft.Windows.ServerManager.ComponentInstaller.InitializeUpdateInfo()
       in Microsoft.Windows.ServerManager.ComponentInstaller.Initialize()
       in Microsoft.Windows.ServerManager.Common.Provider.Initialize(DocumentCollection documents)
       in Microsoft.Windows.ServerManager.ServerManagerModel.InternalRefreshModelResult(Object state)

    I found several web pages with similar errors and fixed a missing MUM file in the C:\Windows\servicing\Packages folder, but running again the System Update Readiness Tool shows that now only one MUM file is missing. The problem is that I cannot find from where I could download the updated package containing this file.
    Checksur.log is the following

    Do you know any solution? Otherwise I cannot add any role to this server...
    Thank you very much

  • Hi Sanjay,

    It appears that the files were corrupted, and couldn’t be repaired by the system update readiness tool. So please follow below steps to replace these files.

    1. First need to gain control over that folder. In order to do this, run the following command:

    takenown /F C:\Windows\Servicing\Packages /D y /R

    Then, assign full control by run:

    Cacls C:\Windows\Servicing\Packages /E /T /C /G “user name”: F

    Note: the user name is the user account that current logs on to the computer

    2. You need to find the same files from the other Windows Server 2008, and copy the files to the C:\Windows\Servicing\Packages folder. Before copy these files, please backup it in the problematic computer.

    How to fix Server Manager Errors after installing updates (HRESULT:0x800F0818 / HRESULT:0x800B0100)

    Hope it helps.
