Hi I would like to disable the Ctrl+Alt+Del key combination on WinNT/2000. Am able to disable all other system key but this! Please show me the way. TIA Anil.
You can't block Ctrl+Alt+Del on NT/2K. Check the KB article Q125614 for more info. BTW - why do you need this feature? Tomasz Sowinski -- http://www.shooltz.com

I need this feature for a kiosk style application. I understand the security implications and also that a new keyboard filter or a replacement GINA dll are the only ways to do this. But just looking for info as there is a paucity of time. Of course, if these are the only ways to do it, then so be it. Thanks Anil

Actually, you CAN disable those keys, but it involves terminating winlogon. I didn't notice any drastic effects, the most notable thing was the lack of ctrl+alt+delete (at that point I could use RegisterHotKey and catch it in my own apps) and the inability to shut down the system. (You can't shut down by ANY MEANS. Blue screen or reset buttons are your only chioces.) Here's what you do: Terminate smss.exe. (You'll need SeDebugPrivelege) Terminate winlogon.exe. There you go. I'm told that all smss.exe does after the system is running is wait on various things and bluescreen when they terminate. So by killing it before winlogon you get rid of winlogon without the bluescreen normally associated with it. If you wanted to get really advanced you could try to figure out which thread in smss.exe was the culprit and just kill the one thread. Use at your own risk! I myself don't fully understand all of winlogon.exe's functions. Stupid name? Yeah. I know.

Create a new user on the computer with limited security. from your administrative account, remove read access from taskmgr.exe. This will prevent the task manager from coming up. There are ways of securing the rest of the 2K C+A+D screen like lock computer with the policy editor. I also have a kiosk program running on XP now, and a locked down user account is the best option. XP is nice because I can use terminal service into the admin account, and let the system auto-logon to the limited account. Telnet and a collection of WSH scripts is also very VERY useful for when you dont want to inturupt the main screen, which terminal services does.
