Last week’s mac techmail was Use Microsoft Remote Desktop from a Mac with CoRD. It talks about using the CoRD application to remotely control Windows systems (or Linux systems using xrdp). I’ve been told that Microsoft provides a Remote Desktop Client for the mac, but I hadn’t found it at the time of the writing. Sounds like some people prefer Microsoft’s tool, and some prefer CoRD so if you’re looking for a client, maybe check them both out to see which would work best for you.
