We have an application that requires a smart card to
access any of the aspx pages. Once I type in my pin #, I
can access the app. BUT Once I pull the Smart Card out,
I can still access the application. The only way the app
requires the smart card again is to reboot my computer.

How can I get the SmartCard (thru IIS6.0 or ASP.NET) to
realize the card has been removed??
