Best (free) utility to remotely control my home desktop

If you are running Windows XP Pro, you can use Remote Desktop. Port forward TCP 3389 through your firewall and enable remote desktop. Then from any windows machine use MSTSC to connect to your computer and use it. If security is a major concern, setup a VPN tunnel and then connect through it. There is no need for any other 3-rd party program IMO.
