Radmin Viewer

Remotely connect to another computer in your network with Radmin Server installed. Radmin Viewer is one of the most famous and secure remote administration tools on the market today.

This tool lets you remotely work on multiple computers using a number of different connection modes. Telnet uses text system commands to connect to other PCs and open text-mode apps. Using File Transfer mode, you’re able to share and remotely manage files and folders. The auto-resume functionality and two-way file transfer are included. With Voice Chat, you can use a microphone and talk to all users connected to the same computer. The Full Control option enables you to control a remote computer with your mouse or keyboard. Also, you’re able to view the remote desktop, shut it down with two clicks and send messages popping up on the remote PC.

Furthermore, Radmin Viewer has an address book feature and allows you to store, edit and group into folders data about multiple remote computers in your phonebook. With it, you can easily get access to a remote computer by double clicking the record.

One drawback is the lack of ability to connect to a computer outside the local network in case that it's behind a firewall / NAT. Competitive applications like TeamViewer can easily connect to any computer running the server application even if it doesn't have a real IP.
