I have a PC tower with no attached display. I use my macbook pro to connect to it with teamviewer. This works fine. However, every so often I get the following when I try to connect. The password is invalid. As I have no monitor, it is a major hassle for me, as I have to disconnect the PC, drag it to my living room to connect it to my TV with an HDMI cable, just to get the password and then drag it back to reconnect. Any help would be greatly appreciated.
