How to add CDO reference in an asp web page

I'm trying to create a ne开发者_如何学运维w email in asp and send it to a mail server using CDO. I believe I need a reference for CDO or Send Email functionality. In the book it says use this:

Set objNewMail = Server.CreateObject("CDONTS.NewMail")

Unfortunately that is now working as it errors out in asp. Now sure how to add the reference, or com object so that it will work through iis using asp. The book I'm referring to is: ASP In a nut shell 2nd addition. "The CDO Object Model" I'm using windows xp or windows server 2003.

use this instead of cdonts
