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, you can easily disable incoming connections to your desktop.

  • Click on the !M icon (the "Monitor") in your system tray. Click on 'Show the connection status' (Fig. 1).

The !M icon is the Monitor to let you manage the NoMachine remote desktop service

  • Click on the button next to 'Connections' to turn off access, i.e to switch the service off.
  • NoMachine will ask you whether you want to re-enable at reboot. Clicking 'No' will keep access to the desktop disabled (Fig. 2).

  • Once disabled, no users will be able to connect, and the NoMachine !M icon will be removed from your system tray.
  • To re-enable connections to your computer, follow the steps above again. "Connections - Off" will be visible at the top of the GUI (Fig. 3). Click on it to re-enable NoMachine connections.
