2. Referred to some Feedbacks or KB articles:

I finally got the solution when I open the IIS Manager->right click Default Web Site->Properties->ASP.NET tab->Edit Configuration...->Application tab-> check the option "Enalbe debugging".
(I did this in IIS6.0, sorry if you have installed other edition.)

After that option has been checked, my Visual Studio Debugger works happily!
