VNC Guide - A Windows Remote Control Setup Guide
VNC (Virtual Network Computing) - Free Remote Control software that you can use to see the desktop of a remote machine and control it with your local mouse and keyboard, just like you would do it sitting in the front of that computer.
= Server (The computer that you want to connect to)
= Client (The computer that you are connecting from)
Notes - Some of the files require an archive utility to extract them. The following is recommended:
IZArc - Download - Home Page

These are the most popular VNC Distributions. However, this guide will only focus on the TightVNC version.
TightVNC - Home Page - Download
TightVNC is an enhanced version of VNC, which includes a lot of new features, improvements, optimizations and bug fixes over the original VNC version. TightVNC is fully compatible with the standard RFB protocol used in VNC, so you can use TightVNC viewer with the standard VNC server and vice versa. But note that the enhancements implemented in TightVNC will work only if TightVNC is used on both sides of the connection.
Here is a brief list of TightVNC features absent in the standard VNC:
√ Viewer Toolbar - The enhanced Viewer Toolbar gives you quick access to features such as Connection options, Connection info, Full screen, Request screen refresh, Send Ctrl-Alt-Del, Send Ctrl-Esc, Transfer files and Disconnect.
√ File Transfers - You can upload files from your local machine to the TightVNC server, and download files from the server to you computer.
√ Local Cursor Handling - Cursor movements do not generate screen updates any more, remote cursor movements are processed locally by the viewer, so you do not see slow remote cursor movements behind the local cursor.
√ Efficient Compression Algorithms - New Tight encoding is optimized for slow and medium-speed connections and thus generates much less traffic as compared to traditional VNC encodings. At the same time, TightVNC supports all the standard VNC encodings, so it can operate efficiently over fast networks, too. Thus, with TightVNC you can work remotely almost in real time in most network environments.
√ Configurable Compression Levels - You can choose any appropriate level of compromise between compression ratios and coding speed, depending on your connection speed and processor power.
√ Optional JPEG Compression - If you don't care too much about perfect image quality, you can use JPEG compression which will compress color-rich screen areas much more efficiently (the image quality level is configurable too).
√ Enhanced Web Browser Access - Includes a greatly improved Java viewer with full support for Tight encoding, local cursor feature, 24-bit color mode, and more. The Java viewer applet can be accessed via built-in HTTP server like in the standard VNC.
√ Support for Two Passwords (full-control and read-only) - The server allows or disallows remote keyboard and mouse events depending on which password was used for authentication.
√ Remote Upgrade - TightVNC servers can be upgraded remotely. This means that you can perform the TightVNC installation working in an active TightVNC session.

Step 1 - Installation
It is recommended to use the latest Development Version for optimal performance and the latest features.
1. TightVNC Self-installing package for Windows - Download
Instructions - Unzip and run. During the installation it is recommended to select "Register new TightVNC Server as a system service". Then reboot Windows. You will now see the TightVNC Server icon in the task bar.
Notes - Windows Defender will detect TightVNC as "Remote Control Software". After you install TightVNC, run a Windows Defender scan and when it is finished make sure to select "Review items detected by scanning". Under "Scan Results", "Action", select "Always allow".
2. TightVNC DFMirage Hook driver - Download (Dramatically improves Server Performance, Recommended but not Required)
Instructions - Run the dfmirage.exe file. The driver will start working right after the installation, no reboot is needed.
1. TightVNC Viewer executable - Download
Instructions - Unzip and create a shortcut for vncviewer.exe to your desktop. Right-click on vncviewer.exe, select "Send To", "Desktop (create shortcut)".
Step 2 - Configure
It is very important to set a password for the TightVNC Server. Right-click on the TightVNC Server icon in the taskbar, left-click on "Properties". Go to the "Server" tab, "Incoming connections" and check "Accept socket connections". In the "Primary Password" box type a password, then Apply and OK. Use eight character passwords for added security. A simple easy way to do this is to use two four letter words in combination. Any character after the first eight are ignored so do not bother making them longer.
You will need the IP Address off the the TightVNC Server for a Client to connect to it. There are different ways to get this:
1. On the Server move the mouse over the TightVNC Server icon in the task bar and the IP Address will show up in a box.
2. On the Server go to the Website www.WhatIsMyIP.com
3. On the Server use the Get IP Utility.
Step 3 - Connect
To connect to the TightVNC Server you will need both the Server's IP Address and the TightVNC Server Password you created. On a LAN you can use the TightVNC Server's Computer Name instead of the IP Address. Launch the TightVNC Viewer from the desktop shortcut. Select the appropriate connection profile:
Low-bandwidth connection = Dial-up
Default connection options = Broadband (DSL, Cable)
High-speed network = LAN
Then type in the IP Address or Computer Name and click on "Connect"
At the "Session Password" screen type in the Password and click "OK". You should now be connected and the Remote Desktop should appear in the Viewer Window. Once you are connected you will be able to use the Remote Desktop as your own. You will be able to do just about everything as if it was on the computer right in front of you except watch video, listen to audio or play games. How much control you have is based on the account level you are connected to. Administrator accounts give you full Administrator rights, Limited User accounts limit you to the same limited rights.
Step 4 - Firewall
TightVNC Server by default will not work with a Firewall unless you allow it access to the following Ports.
TCP 5900 (VNC Viewer)
TCP 5800 (Java Viewer)
Notes - These Ports only need to be opened on the TightVNC Server computer. Port 5800 is used for the VNC HTTP Server so you can access the TightVNC Server with the built-in Java Viewer via a Web Browser. If you are only connecting with the standard TightVNC Viewer this port is not needed. You can disable the HTTP Server in the TightVNC Properties, "Administration Tab", "HTTP server", uncheck "Enable built-in HTTP server". Unlike the standard VNC, TightVNC allows you to choose arbitrary port numbers for TCP/IP connections. The TightVNC default Ports are still the same but if you decide to change these you will need to open the new ports instead of the defaults.
Windows XP Firewall - Home Page
Windows XP comes with a built-in Firewall and SP2 automatically enables it. You will need to add the TightVNC Server to the exceptions list on the Server PC to allow a TightVNC Client to access it. These instruction are for the Windows XP SP2 Firewall.
Instructions - Go to the "Start" Menu, "Control Panel", "Windows Firewall" icon. Under the "General" tab make sure "Don't allow exceptions" is unchecked. Then under the "Exceptions" tab select "Add Program...", from the Add a Program list select "Launch TightVNC Server" and OK. You should now see "Launch TightVNC Server" selected in the exceptions list.
Routers - Port Forwarding
Most Routers come with a built-in Hardware Firewall that needs to allow access to the same Ports. Different Routers have different ways of enabling these Ports, commonly known as Port Forwarding. Use this link for assistance on how to forward these Ports. If your router is not listed here or you are unable to open the ports needed to get VNC working you will need to refer to your Router's documentation or contact the manufacturer of your Router for further assistance.
This is for Advanced Users Only
Although TightVNC encrypts VNC passwords sent over the net, the rest of the traffic is sent as is, unencrypted so using TightVNC over the Internet can be a security risk. To solve this problem, they plan to work on built-in encryption in future versions of TightVNC. In the mean time, if you need real security, use SSH tunneling for all TightVNC connections from untrusted networks. TightVNC features brute-force protection.
