Server Problem

I am running a home website and I have a password and a user set on

that website. I can only access that website and when I do it once on

any computer, till the browser is open, the person gets access to all

of my files and virtual directories and even my FTP server. I know the

easy way out is to close the browser once I am done but I just want to

know is there is any way that I can tell the computer to not store my

password in a cookie and use that cookie all the time till the browser

is exited. I need a way so that my website does not let the computer

store the password. I am running windows XP and IIS 5. Any help would

be apreciated, also I am kind of a noob so please expand that

information a little bit.

Thanks
