Define "domain".
Exchange servers process e-mail in domains. Those are not what we are talking about. We are talking about Active Directory domains. Any fully-qualified-domain-name consists of two parts: a hostname, and a domain name. For example, my Exchange server is named Win2003-Exch.TheEssentialExchange.com. The hostnames on an Exchange server may NEVER be changed while Exchange is installed. That is, Win2003-Exch must always retain that hostname while Exchange is installed. In Exchange Server 2003, the Active directory domain name may be changed - but never the hostname. In the corner case of an Exchange Server that is also a DC, renaming the domain is a breaking change, and is not supported. And is known to not work. Regards, Michael B.

So, there are no easy ways. Some are easier than others, but none are easy. Regards, Michael B. Smith MCSE/Exchange MVP http://TheEssentialExchange.com From: wjh [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 13, 2008 2:07 PM To: Active Directory Admin Issues Subject: Re: Domain rename-Hijacked So, I have somewhat similar project coming up, and can see many ways to this the hard way, but not sure how to do it easy. I have one domain with two DCs...one of which is also an Exchange server. This domain (company.com)is used by two organizations that now want their own separate networks. One organization will keep the current server hardware. It was decided that the other group would be small enough to use SBS 2003. The tricky part is that the org moving to SBS is the one who controls the name for the existing domain and will use it on their network. So, do I demote one DC and then create a new forest and domain, then setup a trust and migrate everyone? Do I run the risk of totally screwing Exchange since it is on a DC?

Is it best to setup a new domain and migrate users to that or try to rename the current one in place. Any suggestions would be helpful Thanks Ryan ~ NEW: CounterSpy Enterprise: Centralized Antispyware - #1 in eWEEK Test! ~ ~ ~ ~ NEW: CounterSpy Enterprise: Centralized Antispyware - #1 in eWEEK Test! ~ ~ ~ ~ NEW: CounterSpy Enterprise: Centralized Antispyware - #1 in eWEEK Test! ~ ~ ~ ~ NEW: CounterSpy Enterprise: Centralized Antispyware - #1 in eWEEK Test! ~ ~ ~ ~ NEW: CounterSpy Enterprise: Centralized Antispyware - #1 in eWEEK Test! ~ ~ <http://www.sunbelt-software.com/product.cfm?id=400> ~
