What is a GINA dll, and is it possible to trap special key combinations using this dll? How can I use this in a kiosk application?

A:
GINA handles part of the login and authentication process for interactive logins on a Windows machine for versions prior to Vista (it has since been replaced by the ICredentialProvider interface).
In general, I wouldn't advocate writing a replacement GINA (or credential provider) in .Net, as you'd inject a dependency on the .Net framework into the Winlogon process - one slip, and you could end up with a machine that refuses to boot.

No. The three finger press (CTRL-ALT-DEL) is specifically made to be NOT INTERRUPTABLE by an application - it actually never sees it, the kernel directly moves to the secure surface (separate session) for security reasons.

@deepukj You're going to have to get dirty with some native code, either building a native GINA/ICredentialProvider or bespoking a system based on (perhaps) a Linux kernel.

It is simple: unplug the keyboard. You can lock down the machine with the group policy editor, ask questions about it at superuser.com
