I uninstalled SharePoint and began getting this error every two or three minutes in the Application Event Viewer:
"WTS event id 0
Service cannot be started. System.Configuration.ConfigurationErrorsException: The value of the property 'value' cannot be parsed. The error is: Some or all identity references could not be translated. (C:\Program Files\Windows Identity Foundation\v3.5\c2wtshost.exe.Config line 17)..."
The error goes on for several more paragraphs. If you need the rest of the error, I will post it.
I had been getting "Event 5586 (SharePoint Foundation) of severity 'Error' occurred xx more time(s) and was suppressed in the event log" many times in a day. Showing an event id 2159 and a task category 59. We didn't need SharePoint installed so I uninstalled it. The WTS error began soon thereafter.
