Login under root through SSH and execute the following:
chmod ugo-x /etc/init.d/S97twonkyserver
or
To manually stop a Service you can run the command “/etc/init.d/S97twonkyserver stop”. When you would like to Disable the Service rename the File and put a “_” in front of it. (Command “mv S97twonkyserver _ S97twonkyserver”). Reboot the NAS when you have changed and check on the Console with “ps-aux” that the Service has not been started anymore.
To enable the Service again just remove the “_” and restart the NAS.
