rsrdp is a portable remote desktop connection management application, which enables establishing multiple remote desktop connections by switching between them within the same application (window). You can create and connect between pre-defined hosts, and provides options to extend or contract the interface for making it easy to view remote desktop windows. What makes rsrdp different from the default Windows Remote Desktop is, that it provides a unified interface for all remote connections, with the utility to connect and disconnect all pre-defined hosts simultaneously.
