Computer Consultants: Remotely control any Windows computer through virtually any firewall!
If you are looking for an inexpensive solution to connect to any computer that is connected to the Internet I have found your solution and it is called HelpDeskVNC. This is a very powerful peice of software that you can add to your website easily to allow remote assistance to any computer.
“HelpDesk VNC gives you instant remote connectivity to any Windows based system in seconds. The remote installer automatically installs, configures, launches and connects the remote computer to the support computer even if it is behind a firewall.”
Some of the featurs I like including being able to customize the client with your logo. I also like that you can use the software on unlimited clients for unlimited amount of time. You can reboot the computer remotely into safemode. You can chat with the user on the other end, and transfer files back and forth. You can track the session time so you know how much to charge the client.
