Invoking the Windows Security Dialog (in C# or VB.NET)

I would like to know how to invoke the Windows Security Dialog (press ctrl+alt+del on a windows workstation NOTE: I don't want the task manager!) programmatically.

ON AN XP WORKSTATION, don't worry about Win7 or Vista

Ideally with a quick example in C# (or VB.NET if you must)

Ive searched many of the DLL's such as msgina.dll and I can't find it anywhere!

Alternatively just invoking the change password screen would be nice!

c# vb.net winapi

You can try call WlxLoggedOnSAS function from GINA or WlxSasNotify from WinLogon. But, I afraid it won't work. But, maybe it will lead you to working method. And it definitely will not work in Vista/W7.

In other side, it might be that Windows Security Dialog can be called only by secure attention sequence ( ctrl+alt+del) by securytt reasons.
