Unable to Unlock Vista Business Host Using Alt-Ctrl-Del

[TeacherMac]

Once the system using Vista Business has been unlocked locally it can be accessed with Gbridge.

When accessed remotely Alt-Ctrl-Del is required to unlock and sending it using the button from the remote does nothing.

Am able to access other systems that don't require a secure logon.

Thanks

There are a row of bottons on the top left side of DesktopShare window, one of them is to send alt-ctrl-del to the remote host.
