15.8.1 Overview


A program named VNC can be used for the following purposes:


Allow you to access a computer at work to use pc/MPR or any other application. Allow a remote location to access a computer at work to use pc/MRP.

Allow technical support at Software Arts to access and trouble shoot pc/MRP.



15.8.2 Requirements


Both the PC at work (should be a workstation and not the server) and the remote PC must have WinVNC installed, and both must have an available internet connection.



15.8.3 Installation


You can download WinVNC from pc/MRP’s website at  Click on Technical Support and select Virtual Network Computing.   Download the file vnc-4.0-x86_win32.exe (VNC version 4 revision 0), into a folder named VNC. (This file is also on the newer install CDs sent out by Software Arts, Inc.)  You may at this time install the VNC server by double clicking on the vnc-4.0-x86_win32.exe file and the files will extract it to a folder named C:\Program Files\RealVNC\VNC4.   Install and set-up the VNC Server program.  The default settings screen may be displayed.   Enter a password and leave the remaining settings in their default mode.


15.8.4 Running VNC


To allow access to a computer, click on Window’s Start Button, select Programs, select VNC, and select Run WinVNC (UserMode).  VNC will start and display a small icon containing the letters VNC in your lower task bar.   Placing your cursor over the icon will display your computer’s IP address.   The remote computer trying to access this computer will need both the password and the IP address.


To access a remote computer, click on Window’s Start Button, select Programs, select VNC, and select Run VNC Viewer, enter the remote computer’s IP address and password when prompted.   If you are running over a slow dial up line, you can speed up screen displays by selecting Options, and check Restrict pixels to 8 bit.


15.8.5 Ports for VNC


VNC & Ultra VNC require ports 5800 and 5900 to be open on routers connected to the Internet.
