SUMMARY
Microsoft Windows Server 2003 does not install Collaboration Data Objects (CDO) for NTS (CDONTS). Therefore, applications that use CDONTS do not function on a Windows Server 2003-based computer.
MORE INFORMATION
Windows Server 2003 provides improved alternatives to CDONTS. To make applications that use CDONTS function on a Windows Server 2003-based computer, update existing CDONTS applications to use one of the following technologies:
  • CDO for Windows 2000
    CDO for Windows 2000 provides a broader functionality set than CDONTS. This functionality includes the ability to send messages through a remote Simple Mail Transfer Protocol (SMTP) server. You can use CDO for Windows 2000 (CDOSYS) in applications that are not Microsoft .NET Framework-based. For example, Microsoft Visual Basic 6.0 and Microsoft ASP are not based in the .NET Framework. You can also use CDOSYS in .NET Framework applications.
  • System.Web.Mail
    The System.Web.Mail namespace provides a managed wrapper for CDOSYS. The System.Web.Mail namespace is only available in .NET Framework applications.
