I have the latest version of TightVNC installed on a workstation. For some reason, I cannot connect to this machine. I can connect via RDP just fine. I have tried uninstalling TightVNC and reinstalling. Same problem. TightVNC taskbar icon says it is listening for connections, but I cannot connect. Tried connecting from multiple workstations. Firewall exceptions for TightVNC are in place. I have also completely disabled the firewall- still unable to connect. Machine in question is not "listening" on port 5900 (verified through Test-NetConnection in Powershell). Tried switching to a different port. Connection problem persists. Any idea how to resolve this problem?
