Active Directory VBS Script for Presentation Auditing

Question

I need a VBS script that can do the following:

1. User logs in to a XP computer and a PowerPoint presentations or web page starts
2. They read through the presentation and then click a links that says: “Click here to complete presentation”.
3. When they click the link it will send their username and time/date stamp to a text file on a server.
4. The next time they log in they will not get the PowerPoint or web page presentation.

Thanks in advance
