Disabling access to your local desktop

If you have installed NoMachine on your PC or Mac and you just wish to use it as a client to connect to another remote computer, there are two ways you can disable connections to your desktop.

1) Via the connection GUI.

Open the NoMachine GUI from the Applications or Programs menu. Click on 'Preferences'. (Fig. 1)

2) Or via the NoMachine !M icon which is located in the system tray of your operating system.

Click on 'Show the connection status'.

5) To re-enable connections to your computer, open the connection GUI from the programs/apps menu and follow the steps above again. "Connections - Off" will be visible at the top of the UI (Fig. 5). Click on it to re-enable NoMachine connections.
