How to configure the TightVNC remote control tool (screen sharing)?How to troubleshoot "The VMRC connection could not be established because protocol version 3.6 or later is required" message? |
When i try to launch the remote control with TightVNC, I get the "The VMRC connection could not be established because protocol version 3.6 or later is required" message, and I can't take the control of the remote host. |

A third software (for example Microsoft Virtual Server 2005) seems to use the same default port than the one used by TightVNC. Please try to change this number (with IDEAL Administration or IDEAL Remote) right click on the remote computer, Remote control, Configure, then Connection tab). If the ‘Auto’ box is checked, the 5900 port is used by default. Try to enter another number, for example 5901 and then relaunch the remote control. |
