New installations will have the default domain of their AD namespace, how do I change this default domain to another name?
As I setup my system I started off with domain name: (myname.com)
then added prefix to represent name server (ns1)
the when I created my company that was added (mycompany)
finally on my exchange server where I also created a backup dns the name server prefix (ns3)
so my AD namespace looks like this: ns3.mycompany.ns1.myname.com
Reason I want to change this is I have mail.mycompany.com setup properly in my DNS but the AD namespace is what gets sent out when using my Exchange 2003 server, hence, AOL & AT&T reject my emails from this server due to the namespace not being what I've configured in DNS.
Hope this all makes sense, I basically want to change my default domain for Exchange to send out according to that. From "ns3.mycompany.ns1.myname.com" to "mail.mycompany.com"
