Windows 2000 Professional doesn't have the remote desktop host built-in like Windows XP does. If you want to control a Windows 2000 machine remotely, you can use something like VNC (which is a free download) or Symantec pcAnywhere.
Netmeeting comes standard with windows...but VNC is awesome. Go to http://www.realvnc.com. It has this really cool server option called Java Viewer...enable this feature and you can connect to youre desktop from any java-enabled browser, just connect to port 5800 on your computer and you get the authentication screen, put in your password and there you go.
