Outbound Fails after Shutdown
Posted on 2004-03-20
I recently installed Windows Server 2003 and Exchange 2003 into an existing Exchange Site (Exchange 2000).
The Exchange 2000 was installed on a Domain controler (don't ask) but the Ex2K3 is installed as a Member Server.
I changed the IP address of the 2000 from 172.16.128.2 to 172.16.128.5. Then I changed the Ex2K3 IP to 172.16.128.2. This way I don't have to change the router settings. Performed ipconfig /registerdns on both machines and made sure a MX record was located in DNS.
I moved the users mailboxes over to the 2K3 and migrated the Public Folders. Everything works great....EXCEPT When I shutdown the old Exchange 2000 server just to test for functionality. Then I can't send mail outbound. Everything else works inbound and internally (both sending and receiving).
I went into the 2K3 server queue and notice the email that I have sent is just sitting there? It is inside the Default SMTP Virtual Server. I will be removing the Exch2K server eventually.
Just to check I started up the 2000 server and then forced a connection of the Queue. The message were sent. So it is still using the Old Exch2000 for relay. How I can make the new Exch2003 be the primary and only server?
