After Security Update KB2756920 problems in Sharepoint 2010

    Question

  • Hello,

    today i experienced problems in my local Sharepoint installation after installing current Windows Updates.

    Symptoms: Problems opening any Sharepoint web site, from Errors in the navigation panes to complete failure to open site (error: an unexpected error has occurred)

    Further analysis of event log and sharepoint log lead to a failure in activating the Security Token Service Application. A "method not found" exception is reported:

    Die Ausnahmemeldung lautet: Methode nicht gefunden: "System.String System.ServiceModel.Activation.Iis7Helper.ExtendedProtectionDotlessSpnNotEnabledThrowHelper(System.Object)"

    I reverted to the most recent restore point and started to analyze which update caused the trouble. After some hours work and several restarts I ended up with the Update

    Sicherheitsupdate für Microsoft .NET Framework 3.5.1 unter Windows 7 und Windows Server 2008 R2 für x64-basierte Systeme (KB2756920)

    Installing all except for this update doesn't cause the problem. Is anybody experiencing similar problems? Other Development systems here do not show this behaviour, even if they are comparably set up.

    The System is: Windows 7 Enterprise, Sharepoint 2010 Enterprise

    Thank You in advance,

    best regards,

    Joachim

  • Hi,

    Microsoft is aware of this issue and here is a brief on the same and the workaround:

    The problem is not particularly with the security update KB2756920, but is occurring due to a bad interaction some of the older hotfixes (like KB976462; KB977420; KB982867) for .NET 3.5 SP1 on Windows Server 2008 R2 RTM/Windows 7 RTM are having with this security update. The exception you are seeing is thrown after installing KB2756920 on Win7/Win2k8 R2 RTM when any WCF service is hosted on IIS using HTTPS in which the machine has a hotfix that only contained System.ServiceModel.dll and not System.ServiceModel.WasHosting.dll. If your server does yet have some of the newer hotfixes which replace these older ones then the problem will occur on installing the security update.

    For now we are offering the following solution to our customers facing this problem:

    -                           Install a newer hotfix for 3.5 SP1 like the one below and then install the security update.

               http://support.microsoft.com/kb/2637518

              If you have already installed the security update then simply install the above hotfix.

    Installing the hotfix will ensure that the security update installs the same version of all the impacted files from the security update package. Since, the security update will install all the latest versions there should not be a concern that your system will be on a version of a hotfix (2637518) you don’t particularly need.

    Thanks

  • Hi,

    Same problem for me today.

    I did many tests but the best solution is to uninstall the KB2756920 update and it will be ok.

  • Same problem here.  Out test environment blew up after installing patches yesterday.  Thanks for tracking down the patch - saved me the trouble of figuring out which of the 8 to uninstall first :)

    I am going to contact our TAM to see if they are getting calls on this yet.

  • I have discovered that the fix only appies to Server 2008 R2 non sp1.

    Once applying the SP1 update for Server 2008 R2 the fix is no longer applicable to the OS.

    Either uninstall the KB fix or update to 2008 R2 SP1.

  • Turns out 2 servers on my farm had automatic updates turned on causing only them to start throwing this error this morning.

    Uninstalled the update, restarted the servers and now they are running w/o errors.

    Wednesday, January 09, 2013 5:13 PM
  • I think, but I am not sure, that the SP1 version of this file is KB2756921.  Whether this breaks with SP1 installed, I do not know.  Our production, Dev, and QA environments are all non-SP1.

  • The following are the available net fixes for R2 SP1

    Microsoft .NET Framework 3.5.1
    (KB2742599)

    Microsoft .NET Framework 3.5.1
    (KB2756921)

    Microsoft .NET Framework 4
    (KB2742595)

    Microsoft .NET Framework 4.5
    (KB2742613)

    Wednesday, January 09, 2013 5:27 PM
  • I have installed KB2756921 on R2 SP1 with no issues as well as all other .net 3.5/4.0/4.5 updates

    (KB2742599)
    (KB2756921)

  • In checking pre and post-KB2756921, there is no difference in the System.ServiceModel file.

  • Confirmed that it is only happening on SharePoint 2010 servers running on Windows 2008 R2 RTM (may also be happening on Server 2008, but I don't have media to test).  Upgrading the farm to 2008 R2 SP1 should resolve this particular issue.

  • This update caused problems on my Sharepoint farm also.  I lost all my navigation and several web parts had errors, although Sharepoint itself was still up.

    I got the same errors as the others here, and uninstalling the update fixed the problem.

    So,any one can tell me ?

    Thursday, January 10, 2013 2:05 PM
  • We also had issues with our SharePoint 2010 instance running on Windows 2008 R2 RTM after installing Windows Updates last night.  Sharepoint logs kept throwing an error saying the Security token service could not be activated.  Uninstalling KB2756920 and rebooting the server resolved the issue for us.
    Thursday, January 10, 2013 3:31 PM
  • Same issues here.  Removing update fixed issue.
    Thursday, January 10, 2013 5:49 PM
  • Windows Server 2008 SP2 is not affected by this issue.  It looks like it is limited to Windows Server 2008 R2 RTM.

  • It would be nice to know what Auth method (Classic or Claims) is used on the web app for people who are experiencing this problem. It may only happen for one mode.
    Thursday, January 10, 2013 8:03 PM
  • It happens regardless of mode, the issue will actually appear on server boot when the Security Token Service initializes.  It doesn't relate to attempting to log into a Web Application.

  • Hi,

    Microsoft is aware of this issue and here is a brief on the same and the workaround:

    The problem is not particularly with the security update KB2756920, but is occurring due to a bad interaction some of the older hotfixes (like KB976462; KB977420; KB982867) for .NET 3.5 SP1 on Windows Server 2008 R2 RTM/Windows 7 RTM are having with this security update. The exception you are seeing is thrown after installing KB2756920 on Win7/Win2k8 R2 RTM when any WCF service is hosted on IIS using HTTPS in which the machine has a hotfix that only contained System.ServiceModel.dll and not System.ServiceModel.WasHosting.dll. If your server does yet have some of the newer hotfixes which replace these older ones then the problem will occur on installing the security update.

    For now we are offering the following solution to our customers facing this problem:

    -                           Install a newer hotfix for 3.5 SP1 like the one below and then install the security update.

               http://support.microsoft.com/kb/2637518

              If you have already installed the security update then simply install the above hotfix.

    Installing the hotfix will ensure that the security update installs the same version of all the impacted files from the security update package. Since, the security update will install all the latest versions there should not be a concern that your system will be on a version of a hotfix (2637518) you don’t particularly need.

    Thanks

  • Hi All!

    We also facing this kind of issue on our infrastructure. Due to an automatic Windows Update in every single servers on the different farms that we had, the KB2756921 had been deployed.

    After that, several customers had identified that some functionality of SP start to fails.

    There are almost all out of the box service (WCF) or ASMX that start failing. The same error message for all of them.

    For example, consulting the ProfileDB cache service we get this response:(http://xxxxxxxxx:32843/efb290de30db4289be4a422f865e2a43/ProfileDBCacheService.svc)

The binding contains a TransportSecurityBindingElement but no transport binding element that implements ITransportTokenAssertionProvider. Policy export for such a binding is not supported. Make sure the transport binding element in the binding implements the ITransportTokenAssertionProvider interface. ----> System.InvalidOperationException: Security policy export failed.

    This is also happening with SecurityTokenService and ExcelServiceCalculation services.

    We tried to install the fix for that hotfix KB2637518, but still not working.

    Our enviroment are Windows 2008 R2 SP1.

    We had opened a Microsoft Case to analyze this situation and try to fix. I will update the post when I get update from them.

    CheerS!
