Windows Server 2008 Server manager refresh failed-error 0x800B0100 RRS feed

  • Question

  • I have a server where I can't get at the roles or features nodes on the server manager because the refresh is failing.  The event log shows this:

    Could not discover the state of the system. An unexpected exception was found:
    System.Runtime.InteropServices.COMException (0x800B0100): No signature was present in the subject. (Exception from HRESULT: 0x800B0100)
       at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)
       at Microsoft.Windows.ServerManager.ComponentInstaller.CreateSessionAndPackage(IntPtr& session, IntPtr& package)
       at Microsoft.Windows.ServerManager.ComponentInstaller.InitializeUpdateInfo()
       at Microsoft.Windows.ServerManager.ComponentInstaller.Initialize()
       at Microsoft.Windows.ServerManager.Common.Provider.Initialize(DocumentCollection documents)
       at Microsoft.Windows.ServerManager.ServerManagerModel.InternalRefreshModelResult(Object state)

    I found a few threads online like http://social.technet.microsoft.com/Forums/en-US/winservermanager/thread/60f8c4c3-cc73-481e-b2fa-fcf8c63d1248, which indicates that it might be a failed windows update.  I checked the CheckSUR.log file, and found this:

    (f)    CBS MUM Missing    0x00000002    servicing\packages\Package_for_KB948881_server_0~31bf3856ad364e35~amd64~~       
    (f)    CBS MUM Missing    0x00000002    servicing\packages\Package_for_KB948881_server~31bf3856ad364e35~amd64~~

    Sure enough, those files were missing, so I looked for those files on another WS2008 machine, and they weren't there either.  I downloaded and tried to install the KB948881 update standalone, but the update failed to install.  Then I tried extracting the files from the msu file manually, and copying them into the \servicing\packages directory, but this only gave me a new error that referenced a file that wasn't in the msu package. 

    (f)    CBS MUM Missing    0x00000002    servicing\packages\Package_for_KB948881~31bf3856ad364e35~amd64~~

    Does anyone have any other ideas on what to try here?

  • Hi Chris,


    This issue can occur if KB948881 package files are missing or corrupt.


    Please download the files from the following site and copy them to c:\windows\servicing\packages (replace the old one).

  • Hello Tim! I tried to go to that URL and use the password that you posted, because I am having the exact same problem with the same update (KB948881) on three of my Windows Server 2008 machines in production, but when I used the password a new screen came up showing that there were no files to download. Could you please help me obtain those files too? I am excited to get them, as it helped out the other user having the problem!

  • Hi Tim. Same problem for me as the one described in the top post (except it’s not the same update).

    Here is the content of the CheckSUR.log file:

    (f)           CBS MUM Missing           0x00000002                servicing\packages\Package_for_KB958483~31bf3856ad364e35~amd64~~

    I already get the 2 other files (Package_for_KB958483_server_0~31bf3856ad364e35~amd64~~ and Package_for_KB958483_server~31bf3856ad364e35~amd64~~

    Could you provide me this missing file (*.cat and *.mum)?

    Thanks in advance,

  • Dear Tim,

    could you please upload the file again?

  • Hi forum members,


    As you may request for different update packages, publishing them in a same thread may cause confusion. Please post new threads to request your update packages and I will provide the download links for you. Meanwhile, I will lock this thread. Thank you for your understanding and cooperation.
