Got rid of Teamviewer. They say it's free for non-commercial use but they randomly shut you down claiming they "detected" commercial use. Tight VNC was an easy install after changing all computers on my LAN to static IP addresses. Setting up No-IP to connect remotely. Goodbye Team-commercial-use-detected-viewer.
