Remote Desk Top

The Remote Desk Top is a nice tool to control a PC.
You might have a small head less system located near the audio and control it over the network by using a netbook. You have all the comfort of a GUI like WMP.
However to login the audio PC must run  XP pro, Vista Business or Ultimate.

TightVNC is a free alternative (doesn’t work on Vista as a system service).
TeamViewer works on Vista.
As it uses port 80, you can use it to connect over the internet without any port forwarding.
It is free for non commercial use.
