Hi, I'm posed a question in my study course for Active Directory and hope someone can help me.
Assuming the following:
Mail Server A is the primary server, while Mail Server B is the secondary mail server. My users will send emails that find their way to SMTP Mail Server A by using the recipient format: firstname.lastname@example.org.
In the event that SMTP Mail Server A goes down, I want SMTP Mail Server B to replace SMTP Mail Server A. This should be done by a VB or C++ program (written by me) that runs on SMTP Mail Server B.
I figure that I can do this by just changing the computer name on Mail Server B from mailserver2.domain.com to mailserver1.domain.com, or should I change IP address instead? Will this pose a problem to AD authentication or registration? What happens if Mail Server A recovers?
Will appreciate any pointers. :)
