Numerous remote administration and connectivity tools exist to help support technicians and IT administrators troubleshoot, maintain, and access systems in different locations. Some are easy to use and require no firewall configuration. Others possess expensive and potentially prohibitive licensing requirements, while delivering more advanced functionality.
Often, VNC – which stands for Virtual Network Computing – is the remote administrative tool of choice for IT professionals. In its earlier iterations, VNC offered a simple, relatively straightforward method of affordably implementing fairly secure access to remote systems.
Over time, the open source community revised and improved the remote access tool. Developer Constantin Kaplinsky, in particular, maintained a project dedicated to delivering an improved VNC remote administration tool that addressed VNC's shortcomings. The result is a more capable application known as TightVNC.
