I am preparing for an Exchange 2010 installation (existing Exchange 2003 environment). Something I'm really confused on is this Disjointed Namespace issue. I understand the concept, and judging from this article: http://technet.microsoft.com/en-us/library/bb676377.aspx?t=exchgf1
I have determined that I am in Scenario 3. My Netbios domain and my DNS domain do not match.
What is confusing me is how do I resolve this. All the resolution steps in that article, and in the Exchange Server Deployment Assistant, seem to focus on Scenarios 1 and 2. There are no steps for clearing up the Netbios / DNS conflict.
Is it a non-issue?
Do I need to rename my Netbios domain?
