Remote desktop from a mac to windows machine, using direct connection eg Ethernet

I work primarily off a Mac-book. I have a windows machine on which I do some .net development. I simply need to be able to use windows remote desktop on my mac to remote desktop to the windows machine, but not over internet. I want the connection to be established over local WiFi, or over direct Ethernet connection between the two machines, if that is even possible. There are many postings on this topic, but non specific to my case.

The closest answer I have come across is this here, which only mentions the possibilities, but the implementation.

Are there any resources I could use to help me set this up, or if anyone knows how to?
