When running via Mozilla Firefox on Ubuntu: Error 1456

Post by BobUnitt »

I'm trying to use UltraVNC from Mozilla Firefox 2.0.0.6 on Ubuntu Edgy to access a local network connected Windows 2000 desktop. I've successfully linked using UltraVNC from Mozilla Firefox on another Windows 2000 Workstation in the same network, so I'm fairly confident that the Server end of the link is OK.

I'm accessing via 'http://[dotted-quad]:5800/' and getting a 'VNC Authentication Screen', to which I enter a Windows 2000 username (no password) but when I press 'OK' I just get a glimpse of part of the target screen, after which the screen goes grey and displays the message 'Error 1456'.

Ii forget, the work around is to uncheck the MS-Logon, so you have only VNC password authentication.
