Some times we may get an error like this 503-Internal Server Error, if check event viewer it will show
The Module DLL C:/Program Files/IIS/Advanced Logging/ClientLoggingHandler.dll failed to load. The data is the error. The Module DLL C:/Program Files/IIS/Advanced Logging/AdvancedLoggingModule.dll failed to load. The data is the error.
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/IISAdvanced_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
