Learn how to install and configure VNC on your computer.
VNC is a free alternative to other remote desktop software. VNC is very light (it doesn’t take much computer resources to run) and easy to use. This guide shows you where to get a free copy of VNC and how to install it. You will also be shown how to configure a few basic settings in VNC.
The first thing you need to do is to install VNC on each computer you want to be able to remote to and set up a few settings. Click here to download a free copy of VNC for Windows from this site. Click here to visit VNC’s website for other versions.
Once you have downloaded VNC run the install package. The first window that will popup is shown below.
This is just a welcome screen that lets you know what you are about to do. Click Next.
The license agreement window will popup. Select I accept agreement and click Next.
The next window (shown above) tells you where VNC will be installed. Click Next.
The Select Components window ask you if you want to install the VNC Server, VNC Viewer, or both. The VNC Server is the program that needs to be running on a computer that you want to remote to with VNC. The VNC Viewer is the program you use to remote to a computer using VNC.
If you are going to be using VNC in an office environment I suggest not installing the VNC Viewer on all the computers. VNC Viewer needs to only be on the computer(s) you will be using to remote to other computers. You don’t want to have everybody being able to remote to anybody’s computer.
Once you have decided what to install, click Next.
The next window shows you where it will create the shortcuts to VNC in the start menu. If you want to be able to access VNC from going to start and All Programs click Next. If you don’t want VNC shortcuts installed in the start menu check off Don’t create a Start Menu folder and click Next.
In an office environment it is a good idea to not create VNC shortcuts in the start menu. This will keep people from easily uninstalling VNC.
The next window lets you set a few options before it installs VNC. The first two check boxes asks you if you want to add VNC icons for the viewer to the desktop and quick launch areas of your desktop. The last two ask if you want VNC server to run as a service if you are installing the VNC server on that computer. Leave those two boxes checked off. If you don’t set VNC server to start as a service when you log off the computer you won’t be able to remote to it again until someone logs in. When you have made your choices, click Next.
The next window just confirms everything. Click Next.
VNC will now install itself. When VNC is finished a window similar to the one below will popup.
This window lets you configure the security settings when remoting to a computer. They are explained below.
Selecting no authentication will allow anyone with VNC to connect to that computer. This is not recommended unless there is absolutely nothing secret on the computer and you can afford the computer to be completely wiped out in a worse case scenario.
VNC Password Authentication
This setting is the recommended way to authenticate a computer remoting to it. By selecting VNC Password Authentication anyone who uses VNC to remote to the computer will be prompted with a password. If you don’t know the password you don’t get in. If you use this feature make sure you use a very strong password so that no one else can remote to the computers.
NT Logon Authentication
This is not an available feature on the free version of VNC. NT Logon Authentication uses the user account you logged into the computer you are trying to remote to another computer with to logon to the remote computer.
Prompt Local User to Accept Connection
If you want the user on the computer you are remoting to to receive a prompt that tells them you are trying to connect to their computer and gives them the ability to refuse your connection when you attempt to remote to their computer check off the Prompt Local User to Accept Connection. If you choose to use this feature you can also set the computer to only prompt the local user if someone is logged on. Check off Only prompt when there is a user logged on if you want that option. If you are going to use the prompt local user to accept connection feature I suggest also using the only prompt when there is a user logged on option with it so that you don’t get locked out.
Once you pick which authentication method you will use click OK.
The next window is the release notes. Click Next.
This window lets you know the installation and configuration of VNC has finished. Click Finish.
You might want to run an antivirus and antispyware scan of your computer now. A good antivirus and antispyware software will pick up VNC as a threat. Once the scan is done set the software to ignore VNC so that the antivirus and antispyware software doesn’t remove VNC.
