 Disable (Ctrl+Alt+Del),(Ctrl+Esc),(Alt+Tab) in NT

- HOPEFULLY THIS SHOULD BE AN EASY ONE SO PLEASE READ  -
    I'm trying to find out how to disable the
(Ctrl+Alt+Del),(Ctrl+Esc),(Alt+Tab) keystrokes in Windows NT after a
user is already logged on.  I do not want to lock my workstation, or
skip the logon window.  I want to disable these keystrokes at the NT
desktop so other users have no way to access the the NT Security/Task
Manager (Ctrl+Alt+Del), Start Menu (Ctrl+Esc), or Window Switch
(Alt+Tab).  I have already tried coding it in Visual Basic, simulating a
screen saver as most recommended, but since it does not work in NT and
only in Windows 95/98 I haven't been able to find any other solution
yet.  I've also tried out shareware/freeware, but don't seem to do the
job.  If anyone could help out with some information on how to do this

You should be using something like Policy Editor to create policies that
restrict what a user can do.  For instance, you can prevent them from
running any applications beyond those you specify.  You can lock down the
desk top and dozens of other things.  I forget if it allows you to prevent a
user from locking a workstation, but if it doesn't, SP4 added a Registry key
that disables the Lock Workstation button.

Best I can offer is tip 0797 and it's links at my NT Tips, Tricks and Registry
Hacks at http://www.jsiinc.com/reghack.htm

If you don't like editing the registry, see tip 1065.

Don't know for sure...but I think to do this through programming you are
doing to have to get a hook to the desktop and watch for all the keyboard
events....Like I said...I am not 100% sure...

Ctrl+Alt+Delete halts all subsystems (Win32, OS2, POSIX)
that is, all user-mode applications are stopped.
The only subsystem continuing to work is the security subsystem
which runs the logon process.

That is, without reprogramming Kernel files you will not be
able to disable Ctrl+Alt+Del. This is by design.

I find this hard to believe. Programs continue to function when you hit
Ctrl+Alt+Del. Think about it: if everything "stopped," how would you be able
to lock a server but still let it do its job?

Robin,

  I have a program that will load in the startup group that was written to
do just what you are looking for.  If you are interested I will send it to
you in email.  It loads part of it in the NT Startup and then the rest of it
when the system loads.  And yes it works.

I am currently using it on public internet kiosk's here is the Dallas area.

No.  NT reserves Cntrl+Alt+Del for its Security Attention Sequence.  This
was included for C2 compliance.  There needs to be a standard way for the
user to interact with the operating system that he/she knows cannot be
compromised.

If you could overide CAD you could create a nice little trojan horse that
looked just like the logon/logoff box under windows and grab passwords.

Look for all documentations for MSGina(.DLL). It's code is public. Microsoft
gives the programmmers the ability to add or create new logon procedures
like fingerprintscanners, irisscanners, smartcards, keycards and so on.
