C++ Net Logon help

Can anyone help me in implementing a C++ program in the lusrmgr program found under system32? I know that you can customize each person to logon in a different way, but I want to be able to have my password program open up at logon, and when all the credentials are met, certain files appear... and when the wrong passcode is entered, the files do not appear.

I was thinking that where the net logon function is, instead of a batch file, you could put the .exe. Inside the program, when the passcode is met, the program would run a batch file revieling the folders.

Can anyone clear this up and tell me how to do something like this?

On NT/2000/XP you use file security and permission to control user access to files. Let the OS handle logon's and password management.

only can be done in 2000/NT/XP Pro... In XP Home you cant change user logon permissions due to limited functions. XPH is not designed for networking... and we only have one user. I want to use the program to protect one folder... JUST one.

I would suggest using a file enryption tool then.
