With searching I haven't found anything definitive on this. Does anyone know why the "Show icon in notification area when connected" option for VPN (PPTP) connections no longer exists in Vista? Is there a hack to get it back? The Network icon that can be enabled in Notification options is for the LAN connection. Through it you can connect/disconnect the VPN connection, but there's no independent VPN status icon anywhere that I've found.
Not having such an icon is more than an annoyance: you can very easily forget you're connected to the VPN.
