You can click "Thanks" under a useful post I guess. I don't have the app installed, but have used rdesktop on my PC before, so it is most likely: RDP server is the IP of your windows machine where you want to connect. Username/Password are your credentials to log in. Domain is optional, and only used if you are connecting through a windows domain. If it is a home PC you can leave it blank. These are the details you log in normally with from the PC.
