You can get a complete list of registry entries by looking at the source. see vncProperties.cpp. (I've attached the file from 1.2.1 in this mail) search for "vncProperties::Load" and go down a bit: vnclog.SetMode(LoadInt(hkLocal, "DebugMode", 0)); vnclog.SetLevel(LoadInt(hkLocal, "DebugLevel", 0)); // Disable Tray Icon m_server->SetDisableTrayIcon(LoadInt(hkLocal, "DisableTrayIcon", false)); // Authentication required, loopback allowed, loopbackOnly m_server->SetLoopbackOnly(LoadInt(hkLocal, "LoopbackOnly", false)); if (m_server->LoopbackOnly()) m_server->SetLoopbackOk(true); else m_server->SetLoopbackOk(LoadInt(hkLocal, "AllowLoopback", false)); m_server->SetAuthRequired(LoadInt(hkLocal, "AuthRequired", true)); m_server->SetConnectPriority(LoadInt(hkLocal, "ConnectPriority", 2)); Here you see some values read from the registry. But you'll have to be careful where the data is read from: see the "hkLocal" in the calls above. They're going to different registry keys: hkLocal is HKEY_LOCAL_MACHINE/Software/ORL/WinVNC3 hkLocalUser is HKEY_LOCAL_MACHINE/Software/ORL/WinVNC3/<USERNAME or SYSTEM> hkDefault is HKEY_LOCAL_MACHINE/Software/ORL/WinVNC3/Default hkGlobalUser is HKEY_CURRENT_USER/Software/ORL/WinVNC3 IIRC. You'll find some interesting settings there. AFAIK there's nothing to disable "kill all clients", but you can remove the whole menue or even the icon in the taskbar. Hope that helps!
