VNC Server Configuration
The VNC Server installed with NetPhantom is the VNC Server Free Edition that has some limited capabilities compared to the full versions. This version is a free version from RealVNC Limited. See their web site for more information. Only the Server and it's Settings programs are installed under the RealVNC sub-directory. The main limitation is that it's communication between the Server and Client is done without encryption. As this communication is tunneled through the NetPhantom Remote Assistance Server using an 128 bit SSL encrypted connections, it becomes secure. See the documentation on Remote Assistance for more information.
VNC - the original cross-platform remote control solution
VNC stands for Virtual Network Computing. It is remote control software which allows you to view and fully interact with one computer desktop (the "VNC Server") using a simple program (the "VNC Viewer") on another computer desktop anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view a Windows Vista desktop at the office on a Linux or Mac computer at home. For ultimate simplicity, there is even a Java viewer, so that any desktop can be controlled remotely from within a browser without having to install software.
VNC is in widespread active use by many millions throughout industry, academia and privately. There are several versions to choose from, including a free version and some substantially enhanced commercial versions.
NetPhantom integration with VNC
To enable NetPhantom Support to help you with a problem or just general guidance, there are a number of steps that needs to be performed. First, your NetPhantom Editor needs to be configured to communicate securely using SSL to a Remote Assistance Server such as the one provided by Nexum Technologies at the address netphantom.com; the web site http://netphantom.com is running a NetPhantom Server installation enhanced with a Remote Assistance Server. When NetPhantom Supports is using VNC to interact with your machine, you are able to see everything going on (such as keyboard or mouse input), and also to work simultaneously. This work is transferred to the remote VNC used by NetPhantom Support.

In order to speed up image transfer, check the options While connected (Remove wallpaper, Remove background pattern and Disable user interface effects, such as fade, scrolling) that are used for enhanced screen display. These options are located on the Desktop tab as shown below. Also make sure to select the option Do nothing as action When the last client disconnects.
Screen capturing is handled on the Capture Method tab and it is recommended to select Poll for changes to the desktop and Capture alpha-blended windows. When a VNC Client Viewer connects, it has a setting for the color depth of the images transferred.

Launching VNC Server
In the NetPhantom dialog box VNC Server, click the button Launch VNC Server. The Server will keep on running until you exit NetPhantom Editor or you stop it with the button Stop VNC Server. You may close this dialog box and also the previous dialog box for Remote Assistance. The program states for VNC Server and the communication link(s) to the Remote Assistance Server will still be open until you explicitly stop or close them (or exit NetPhantom Editor).
