Source: GroupWise WebAccess Agent
Explanation: The WebAccess Agent must know the path to its gateway home directory. This path is specified by the /ph startup switch.
Possible Cause: The /ph startup switch was not used on the command line or in the strtweb.ncf or strtweb.bat file.
Action: Include the startup switch. See "Using WebAccess Agent Startup Switches" in "WebAccess" in the GroupWise 6.5 Administration Guide.
