User login / logout program

I am looking for a program written in asp or asp.net that will track the time that users login and logout? using an access database. This program will be used by multile users at the same time so you will have to be able to close an account (add the logout time) after several other people have logged in. There should also be an administrative side that allows you to view account information. Here you should be able to track the amount of time a user has spent logged onto the computer, by days weeks, months, and total time. You should also have a general search fucnction to retrive records.
