It is not supported to rename any server where Exchange is installed. This means specifically that if Exchange is installed on a DC, you may not rename your domain. Otherwise, it works OK in a lab. I've not needed to do it "real world". ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Carl Houseman Sent: Wednesday, July 26, 2006 12:35 PM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Changing Domain Controller Name Everything is on a different machine? I've lost track since I never really knew where everything was to begin with. All I knew is you were going to move Exchange 2003 "from one domain controller to another domain controller" (your words). Some experts have bad things to say about renaming the domain when Exchange is in play. But Microsoft does support it so it must work some of the time . Look here, especially the first two matches: http://www.google.com/search?hl=en&q=exchange+domain+rename Carl ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Amit Kapoor Sent: Wednesday, July 26, 2006 2:43 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Changing Domain Controller Name Carl My Exchange Server 2003 is on a different machine and Active Directory is on a different machine. If I upgrade my active directory to windows 2003, then I can rename the domain name through netdom command. But I just wanted to know its impact on Exchange Server 2003, because Exchange depends on Active Directory.

But yes, you can install a second Exchange server and migrate users from one to the other. That's regardless of whether either Exchange server is running on a DC. You understand that the AD domain name does not affect your ability to receive and send Email as any other domain name?
