Problem in loading GinaStub.dll

[Roshan R.D]

Hi All,

I am working on Custom shell, and I want to disable the Ctrl+Alt+Del key, to
do this I have downloaded GinaStub code from XPeFiles.com.
I compiled the code and added the dll under D:\WINDOWS\system32\ginastub.dll
(I have a dual boot system D: is XP embedded for me)
I also added registry key GinaDLL (string value)
HKLM\SOftware\Microsoft\Windows\CurrentVersion\Policies\system
I added the path of ginastub.dll as mentioned above and restarted the
machine.
On next restart I got the error "The Logon Interface DLL
D:\WINDOWS\system32\ginastub.dll failed to load. Contact your system
administrator to replace the dll or restore the original DLL.
Another thing that I want to ask is if I remove taskmgr.exe from system32
and use custom shell, will I be able to override the Ctrl+Alt+Del key? In
short I need to hide the Windows Security popup in my custom shell upon
hitting this key combination.

Thanks & Regards
Roshan.

Roshan,

THe only way to do this is as you described with the ginastub or by creating
a keyboard driver that traps the key combination. I had good luck with a
custom shell and the ginastub. The only issue I found was that the
ctrl-alt-del sequence causes a momentary flash of the screen as the sequence
is intercepted and the ginastub returns no action.

By the way - removing taskmgr.exe the ctrl-alt-del will still popup the
windows security dialog - only you will not be able to select the task
manager option.

Hope this helps

Martin.

Just to add to this a little bit more.

Please keep in mind that replacing Gina is the solution that will only work for XP/XPe. It won't help you much with the Ctrl-Alt-Del
sequence in Vista if you happened to port your image (applications) to this OS in future.

From my own experience, changes in the keyboard driver is the better and easier to implementation solution, IMHO.

Thanks Martin and KM for your reply,

Martin, will you please help me with your ginastub code, where did you get
this code code from? Can you please provide me the link from where you have
got this code from? (I read on internet that ginastub on Microsoft site has
some problem.)

KM, can you help me with the link to get the code for keyboard driver.

Many Thanks
Roshan

Roshan,

Sample keyboard driver code can be found in WIndows DDK.
