VNC, Virtual Network Computing from AT&T Labs Cambridge (UK) allows a Mac client to control remotely the server machine (not Mac, sorry). It's neater than this sounds! Remember that Windows does not allow administration without console access, unlike Macs and Unixes that can run headless (no monitor or keyboard or mouse) and still function well.

Xtension can also control a CP290 for X10.
