When I tried to increase the ADFS Trace -log level using the Microsoft instructions , I am getting the below error:
C:\Windows\system32>wevtutil sl "AD FS 2.0 Tracing/Debug" /L:5
Failed to read configuration for log AD FS Tracing. The specified channel could not be found. Check channel configuration.
I managed to find the solution(using this blog post)- The Log file names were changed in ADFS 2.1 from AD FS 2.0 Tracing/Debug to AD FS Tracing/Debug
Old Path:
%SystemRoot%\System32\Winevt\Logs\AD FS 2.0 Tracing%4Debug.etl
New Path:
