ConnectPriority
By default, all WinVNC servers will disconnect any existing connections when an incoming, non-shared connection is authenticated. This behaviour is undesirable when the server machine is being used as a shared workstation by several users or when remoting a single display to multiple clients for vewing, as in a classroom situation.
ConnectPriority indicates what WinVNC should do when a non-shared connection is received:
0 = Disconnect all existing connections.
1 = Don't disconnect any existing connections.
2 = Refuse the new connection.
