Roles and Features wont load RRS feed

  • Question

  • Hi,

    I have recently come across a problem with Server Manager on my Windows Server 2008 Standard edition install. When Server Manager loads, it shows "Error" against both the roles and features section, and if i click error details it says:

    Unexpected error refreshing Server Manager: No signature was present in the subject (Exception from HRESULT: 0x800B0100).

    Checking the Event Viewer is shows the following error:

    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.Common.Provider.Initialize(DocumentCollection documents)
       at Microsoft.Windows.ServerManager.ServerManagerModel.InternalRefreshModelResult(Object state)


    I have run the System Update Readiness Tool which shows the following in the log file:

    Now KB961260 relates to an IE Update, which i have since installed and now the only update that is showing in the Windows Updates screen is the .NET Framework 3.5 Update which it wont let me manually install and Windows Update wont install it either since i need to run this via Server Manager apparently. Those 3 .mum files also dont exist in the packages directory.

    Can someone please let me know what i can do to fix the Server Manager so i can access the roles and features section again. I really hope there is a solution that doesn't involve a rebuild!!

    Thanks,

    Peter

  • I finally fixed the problem i was having. Basically, i copied those 3 .mum files from another Server 2008 installation i had onto the server that was having the problems and then i ran the System Update Readiness Tool again. This returned a log with no errors and the Server Manager successfully loaded the features and roles sections!!!
