Are you getting any specific error? the mail code is very simple stuff and your's looks correct to me.
;;;Is there a possibility that I`m missing any .dll files???
If this was the case I believe you would be getting one of two errors:
1..'Invalid class string' = SMTP service is not installed
2..'failure to create object error' = You no not have CDONTS available to you or you have a syntax error in your code where you create the mail object.
