.NET 3.51 update issues

Security update for Microsoft .NET Framework 3.5 on Windows 8.1 and Windows Server 2012 R2 (KB2966828) causes a problem to .NET 3.5 on Server 2012R2.

Two services fail to start:

• Net.Msmq Listener Adapter. The service did not respond to the start or control request in a timely fashion.
• The Net.Pipe Listener Adapter service failed to start. The service did not respond to the start or control request in a timely fashion

There is also an Application Error Event 1000: Faulting application name: SMSvcHost.exe, version: 3.0.4506.8003.

Solution: uninstall KB2966828 and hope that it will be superseded or revised by Microsoft in due course.
