Can I use Windows 2000 Professional as a host with remote desktop?

Is there any add-on software or way to use Windows 2000 Professional as the host computer in a remote desktop session? I know there is a client side add-on, but I need a host add-on. I will be connecting with a pc using Windows XP Home.

Yes there is. RealVNC software will allow you to remotely control other computers. Install the VNC server on the host and access it from the client computer with the VNC client software.

If you are using it over the internet I would purchase the secure version.

Try one of the VNC distributions.
