ASP Logout and windows Authentication

[Revera]

I have set up my web page to authenticate using clear text to force a login each time a new browser window accesses my page - so far so good

I now want to log the user out so the next time a user accesses the site they too are prompted to log in. I kill the session and redirect them off to an unrelated site. If the browser is left running and another user opens my page they log in automatically usng the previous users credentials. How (using code)do I stop this from happening

I am rewriting the software for our bank's ATM machine. The problem is that we have forgetful customers and sometimes they walk away while their card is still in the machine and the screen still asking for another transaction.

How can I fix this so that the next guy at the machine can't withdraw money from the forgetful person's account?
