Seting up a backup domain controller
Posted on 2011-05-04
I have a windows 2003 Domain controller that also serves as a DNS and a DHCP server; I also have a Windows 2003 server with Exchange server running on it, the other function of the Exchange is a secondary DNS server. We have just migrated off the Exchange server to an online hosted Exchange server and they want me do away with the old Exchange server. The down fall of this is there are several of our web sites that have the old Exchange server IP address hard coded in the scripts for outbound emails, both of these servers are VM servers.
Now my company wants me create new server with two functions:
• Backup Domain controller so that if the main Domain controller goes down at any time the backup would kick in until the main controller is backup
• SMTP Relay for our outgoing automated email programs.
Can I have a Backup domain controller?
Should I create a completely new server or can I uninstall Exchange and use the old Exchange server.
