Solution 1

On MDI form, you can open the login form in FormClosing or FormClosed event handler.

Solution 2

You could simply use the Closing or Closed event or even the ApplicationExit of the Application to restart your program.

Have a look here for more info:

Good luck!

I'd handle this very close to the program entry point. If you look in your main function you'll probably see something like this:

Application.Run(new Form1());

You can create a loop here to do your stuff:

while (condition)
{
    Application.Run(new LoginForm());
    Application.Run(new MainForm());
}

but you'll need some extra logic for the authentication etc..
