The Arma 3 server name and join password are stored in server.cfg. The easiest way to change them is through the Config Editor, then restart the server so the new values are loaded.
- Open your Arma 3 server in the control panel.
- Click Configuration Files.
- Find
server.cfg, then click Config Editor.
- Change Server Name and Server Password as needed.
- Click Save & Exit.
- Restart the server.
Leave the server password blank if you want the server to be public. Use a password when you want a private training, unit, or event server where only invited players can join. If players still see the old name in the browser after a restart, wait a few minutes and refresh the server list.
