That’s when I stumbled across TeamViewer – free, open source, based on VNC, and extremely simple to use and setup (which is nice, so you don’t have to send complex instructions to the remote user). Both clients download a small executable and run it. You are given a connection ID (which looks like an ICQ number). You give the remote user your connection ID and they click connect. Simple as that, and it works through a firewall. It’s a little slow, but it works great for a remote desktop connection through a firewall.
