Both the DLL’s which were mentioned in the Event we present in respective Directories but still IIS was not able to detect them. So, to fix the issue
1) Copy “C:/Program_Files/IIS\Advanced_Logging/ClientLoggingHandler.dll” and “C:/Program_Files/IIS/Advanced_Logging/AdvancedLoggingModule.dll” to %windir%/System32/
2) Edit C:/Windows/System32/netsrv/config/applicationHost.config and Search for following Lines
add name=”ClientLoggingHandler” image=”%ProgramFiles%/IIS/Advanced Logging/ClientLoggingHandler.dll” add name=”AdvancedLoggingModule” image=”%ProgramFiles%/IIS/Advanced Logging/AdvancedLoggingModule.dll”
and change it to
add name=”ClientLoggingHandler” image=”%windir%/System32/ClientLoggingHandler.dll” add name=”AdvancedLoggingModule” image=”%windir%/System32/AdvancedLoggingModule.dll”
3) Restart IIS
