I have programs I have written for NT and W2K servers that have calls to Server.CreateObject("CDONTS.NewMail").<BR>They work fine on a server but not on XP Pro SP2 Bld 2082 with IIS loaded. I have MDAC8 installed as well as Vis Interdev server and .NET Enterprise Architect. I get an ASP 0177 error with invalid class string. Any clues as to get the mailer working so I can use this as a test platform during my commute? Thx.
