Thanks for the explanation.

If you got the message of "VNC authentication failed!" in reverse connection ONLY with using MS logon but NOT using simple uVNC, then I really be surprised.

For the best I know, there is no authentication with reverse connection in both situation.

If you can provide more detail of your config. and the testing environment, may be the developer or other experienced users can give a better advise.

That's exactly what I think happened, but I'm not sure when I'll be able to verify, as the other box is not receiving AC power at the moment.
