Does anyone know if CDONTS is shipped with IIS 5.1 on XP Pro? I am getting invalid class string when trying to call CDONTS.NewMail which leads me to believe its not been installed. How do you tell?
It isn't. It's been fully depreciated in favor of the newer CDOSYS.
Can you use classic ASP with that or not?
Yep. just fine. It's just a slightly different component. All of the docx for it can be found at MSDN.
