I ask the user to my site to enter name,email and password. In response i generate and id and give back to the user. I track the user through this id. In an event he forget this id I ask him to enter his email and password so that i can send him back the id. I can get his id by searching the database with email he sends to me. My problem is how can i send him/her mail autometically mentioning his forgot id ? I am using iis4.0. Can any one help me out regarding sending the forgot id (that i get through search) via email ?
