Logon.exe opens the logon prompt and fails to fill password

Hi,

I'm trying to test the logon.exe tool using a script like:

sleep 5s
c:\windows\logon.exe -p myPassword

I start the script, lock my station and wait.

The logon prompt is opened, I see the tool filling the password field and then this field is immediately erased...

I'm logged as Administrator on Windows XP SP2.

Do you see any reason why it fails?

Thanks,
Damien.

Fixed.

Actually, the logon.exe needs the keyboard layout of the logon prompt to be US (Qwerty).

This layout is independent from the user's current locale.

You can change this default layout by following instructions at http://www.windowsitpro.com/article/configuration/how-do-i-configure-the-default-keyboard-layout-during-login-.aspx

It did the trick for us.

It seems also that the logon.exe does not accept uppercase characters.

Regards,
Damien.

Yes and no, it emulates key presses by generating low level key press/release events using scan codes of QWERTY keyboard layout. See http://msdn.microsoft.com/en-us/library/aa928103.aspx for ideas. In case of some other keyboard layout you can feed it a password value which is literally different from the real password, but provides the same results. No changes needed in the layout. Here is what I mean, if your password is ZZZ and on your keyboard letter Z appears where letter Q is on the QWERTY keyboard, specify QQQ as the password value and it should work with our keyboard layout.

It should be able to handle special symbols and upper case characters of Latin alphabet (e.g QWERTY layout mapping). For such symbols/characters it first emulates key press of the Shift key, then key press of the character key, and then release of both keys.
