How can we get SMTP to work on Windows 7 (Development Environment) as we used to just be able to turn it on for a windows XP box.


SMTP isn't included in Windows 7 by default. But you can install Remote Server Administration Tools that includes SMTP Server Tools for Windows 7. It enables IT administrators to manage roles and features that are installed on remote computers that are running Windows Server 2008 R2 but it can be installed ONLY on computers that are running the Enterprise, Professional, or Ultimate editions of Windows 7.



First install Remote Server Administration Tools, and then upgrade to Service Pack 1 as it CANNOT BE INSTALLED on computers that are running Windows 7 with Service Pack 1 (SP1).
