As its name describes, Remote Desktop Manager is an application that you can use to access and control various computers using a VNC (client-server) connection.
The main reason to use Remote Desktop Manager with other PCs is its license - completely free - and capacity to store configurations for the computers that you work with.
The program is very easy to manage, thanks especially to an accessible and attractive Windows-inspired interface. You can save information from your sessions in .mdb format, and take advantage of a small search filter which really comes in handy if you're working with various computers.
