Over the past few weeks, I have seen errors appearing in Windows logs, with reference to the following:
The description for Event ID 100 from source System.ServiceModel.Activation 4.0.0.0 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: System.InvalidOperationException: Etw registration failed with error code e. at System.Runtime.Diagnostics.DiagnosticsEventProvider..ctor(Guid providerGuid) at System.Runtime.Diagnostics.EtwProvider..ctor(Guid id) at System.Runtime.Diagnostics.DiagnosticTrace.CreateEtwProvider(Guid etwProviderId) at System.Runtime.Diagnostics.DiagnosticTrace..ctor(String traceSourceName, Guid etwProviderId) w3wp 1540
This is a Windows 2008 server, launching sites under IIS and .NET 4
These errors occur every 30 seconds or so, and I have no idea where they come from.
All sites run under the default ASP.NET v4.0 application pool.
Has anyone else had this error before?
I really do not want to do anything like .NET recovery, unless it is needed, because it is a live server and the sites used on it.
Thanks for any help.
