The solution I use is VNC (
http://www.uk.research.att.com/vnc )
This is an open source / cross platform remote desktop
tool. Basically it ships the screen pixels back from a
remote server to a local client, and forwards mouse and
keyboard commands the opposite way.
Not only can you run any program on the remote computer
you can also watch what someone is doing - invaluable
for help desks tracking user problems.
Both the server daemon and client browser are available
for windows + unix.
