MSRA, also Microsoft Remote Assistant, works like Teamviewer as a connection between two devices. For MSRA you don't need to install anything, and it only works on Windows and in the local network. The Remote Assistant creates an incident file with the IP of the computer, this file can then be downloaded to establish the connection. MSRA can be started by clicking on an already existing device in the hardware and selecting "Start MSRA (local network)" under Manage.
