oh god, SMTP on a W2k box... most frustrating thing I have tried to do (note tried, and died).
You may have a process hung. You can check via the taks manager, or my prefered method TLIST -T from the command prompt (need the W2k reskit).
Man, I don't know why ASP and SMTP is such a bitch on W2k, it just is. Also check your message syntax in your ASP page. Try to dump the output to a text file before you send it to the SMTP server. There might be something not right (space, comma, CR, etc).
Send a note to Goatboy, he might be able to rattle something off the top of his head.
As for "Some one please tell me why computer make our lives easier?" I have no real clue, but it keeps asocial people employed, and out of sight from the general public, where they can scare others.
