StorNext: Error in Windows - Unable to Open Configuration File: No Such File or Directory

During Windows startup or a StorNext File System Service restart, an error dialog appears stating:
(Critical) StorNext File System FSS 'snfs1[0]': error: Unable to open C:\Program Files\StorNext\config\snfs1.cfg: No such file or directory

This is typically caused by the removal of a file system configuration file without removing its corresponding autostart entry in the StorNext File System Startup List. (The name of the problem file system is listed twice in the error message: one is in quotes and has a number in square brackets appended to it, and the other is the name of the config file listed, minus the '.cfg' suffix.)
