Log level Synergy service

I use the excellent tool Synergy for using my mouse & keyboard on multiple computers. It can also run as a Windows Service, see the manual.
Annoyingly, it kept showing me warnings about not finding the server side when I'm at work (it's configured to work with my home PC as the server). Here's how to set the log level for the Synergy service on Windows:
- Stop the running service.
- Start the Synergy program from the Start Menu.
- Click 'Autostart', then 'Uninstall' - that uninstalls the service.
- Set the logging level (to Error).
- Click 'Autostart', then 'Install' - that re-installs the service again.

Now the service will remember the configured logging level.
