ChunkVNC is an open source UltraVNC wrapper. The project is released under a GNU License. You're free to use ChunkVNC for both commercial and personal use.

ChunkVNC consists of three parts, InstantSupport, Repeater and Viewer.
1. InstantSupport is a customizable AutoIt script that is compiled into a single executable named InstantSupport. When InstantSupport is launched it will extract the UltraVNC server to a temporary directory, generate a random ID and securely connect to the repeater. InstantSupport also shows the customer a friendly interface with a large ID number to relieve confusion. The InstantSupport tray icon gives you the "Install Service" option which will permanently install the server onto the customers computer. This also gives you the ability to control UAC in Vista/7 and reboot the customers computer.

2. Repeater is the software that both InstantSupport and the viewer connect to. Preferably the repeater will be running constantly in a fixed location.

3. Viewer is the part of UltraVNC that will connect to the repeater so you can control the remote computer. The ability to transfer files and blank the clients screen are just some of the many features of the viewer.

After you have downloaded and extracted ChunkVNC
1) Copy the repeater folder onto the computer that will be acting as the repeater.
NOTE: The repeater must be running at all times on ONE computer for ChunkVNC to work.
2) Run the repeater
3) If you are behind a router you will have to setup port forwarding or else InstantSupport won't be able to see the repeater.

The following ports will need to be forwarded to the IP address of the computer running the repeater: * 5901* 5500

This also gives you the ability to control UAC in Vista and reboot the remote computer.

Repeater is the software that InstantSupport sets up the UltraVNC server to connect to. Once a client is connected to the repeater you can control their computer just by knowing their ID number.

Viewer is the part of UltraVNC that will connect to the Repeater so you can control the remote computer. The ability to transfer files and blank the clients screen are just some of the many features of the viewer.
