Internet Information Services (IIS) logging needs to be enabled for IIS 7.0 in order to troubleshoot issues with the Symantec Endpoint Protection Manager.
Enabling IIS logging is a two step procedure. Logging must first be enabled for the entire web site. It must then be enabled for the specific virtual directories which need to be logged.
Enabling Logging for the Symantec Web Server
Enabling Logging for the Symantec Web Server Virtual Directories
These steps begin inside the Internet Information Services (IIS) Manager window which can be opened by following steps 1 through 6 (above). Perform the below steps on any virtual directory which needs logging enabled.
Logging is now enabled. Please be sure to disable logging after it is no longer needed by reversing these steps.
