Having used TeamViewer for some years on the same machines, it has started to give trouble - I frequently get the "authentication rejected" message when connecting to one (Windows 7) PC at home that I used to be able to connect to from the office without any problems. One day I did connect in the morning but not later on in the day. The PC shows no other general problems of any sort. It is a high-end Dell laptop. It is left on constantly and has a screen inactivity timeout but no timed screen lock i.e. I come back home, hit any key or move the mouse and all is as-was. No-one but me uses the 'remote' PC. The PC has two screens connected (ext one via HDMI).
Today I got home and managed to catch the problem with my own eyes, and tried connecting from another laptop, and failed. On the "remote" machine (though now in same room) the screen was on (NOT timed out) and was showing the TV window, but that window alone was black apart from the Partner ID box and had the 'busy' mouse pointer. In this state, I still failed to connect with the second laptop (I got auth rej msg). I had not touched the keyboard or mouse.
When I did nothing more than move the mouse on the 'remote' PC, the screen suddenly went black (as if upon a timeout). When I then tried to connect from the other PC, I had no problem at all and could repeatedly connect.
I then disconnected and let the screen inactivity timeout take place and tried reconnecting with the 'remote' screen being black. I could connect ok.
Any help with this would be appreciated. There is obviously no actual credentials problem at all (they are all stored in my TV account) but there might be a video problem?
Thank you.
