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
