We are running WinNT v.4.0 with Service Pack 6 and MS Exchange Server is not installed. I have an ".asp" page that trys to send mail via a CDONTS object but the page fails. My error reads: Server object error 'ASP 0177 : 800401f3' <BR>Server.CreateObject Failed <BR>/AdminShag/admin_newsletter_sendx.asp, line 3 <BR>Invalid class string<BR><BR>I'm definitely not an NT administrator and to be honest, I don't know how to proceed. What do I need to do to get CDONTS to work? Any help would be greatly appreciated!
