To install and run Native Abstract Windowing Toolkit (NAWT), you need to create a Virtual Network Computing (VNC) server password file. The VNC server default setting requires a password file that it uses to protect the VNC display against unauthorized user access. You must create the VNC password file under the profile that starts the VNC server.</li>
