You can't write a program to "lock the System" in Java because all someone would have to do is push Ctrl-Alt-Del to kill the JVM running your program. You'd be better off just putting a password on the screensaver.

I'm not sure what you mean when you say "allow the user to use the internet with a password"? Are you writing your own web browser / email client? Are you trying to control access to native email and browser applications? The only way I can think of doing this in Java is to password protect a Java browser and email client that you have written yourself.

Of course, if you install these on a window machine, you'll have to take IE and Outlook off the machine, or people will just bypass your password protected apps.

Hi, Nate why do u think of blocking the applications such as IE & outlook .I have a suggestion of removing the connection of the proxy server.i.e the proxy server settings allow u to access the internet,if this connection is disabled then automatically u will be unable to use the internet.Is this right?if so help me out.

Yeah... if you remove the connection to the proxy server you will be unable to access the internet... but how are you going to re-enable it when a user requests it? I don't know how a Java program could re-enable the network connection in Windows...
