Great open source solution for remote computer management and diagnostics

The UltraVNC Single Click version has been great to provide to my clients without having to worry about licensing issues. Many of them are computer novices so not having to talk them through installing more complex software and changing network settings has been a real time saver.


UltraVNC is a great open source solution for remote desktop connections and being free for commercial use means big savings if you've got a lot of users that need occasional support. The software is small and easy to install and includes a variety of options to suit different Internet connection speeds. There's also a Single Click version that allows you to create a custom executable that can be distributed to customers preconfigured to connect to your IP address which saves them needing to configure the firewall at their end to support incoming connections.


Compared to some proprietary software like Microsoft Remote Desktop and TeamViewer the screen updates appear to be a little slower and there can be occasional glitches that need a screen repaint. While not a big deal for remote support incidents it may be worth looking at other options if you're intending working over a remote connection for extended periods of time.
