The following information was included with the event:

Cause
 

  • The Microsoft.IdentityServer.ServiceHost.exe.config file has been edited, and contains data that has caused the trace utility to throw an exception. 
  • This is typically caused by having incorrect syntax in the Microsoft.IdentityServer.ServiceHost.exe.config file. 
  • The most common cause of this is where customers have modified the SwitchValue parameters for diagnostic tracing, and they have entered an invalid value for SwitchValue. 
  • It is important to note that the SwitchValue value is case-sensitive, so adding 'verbose' rather than 'Verbose' will cause this issue.

 

Resolution

 

  • Edit the Microsoft.IdentityServer.ServiceHost.exe.config file in:

 

    • AD FS 2.0: %programFiles%\Active Directory Federation Services 2.0\
    • AD FS 2.1: %winDir%\ADFS\

 

  • Ensure that any changes you have made to this file are syntactically correct, such as case-sensitivity and spelling of SwitchValue values in the diagnostic tracing sections of the file
