This is where I disagree, we are running a dummy domain now as our root so 1.a.com and 2.a.com can keep the root domain and the child domain without issue.
Once the split happens 1 side will have a root domain controller (fsmo etc..) and a child domain. The other will have to seize rolls on the root domain controller (fsmo etc..) and the child domain controllers. Clean up is simply asdiedit out the "other" sites domain controllers. As for renaming the Domain we could care less, it's a dummy anyway (2003 AD native mode). We have setup alias for our Organization inside Ad so people can logon properly I.e. j...@abc.corp they will stay with each org. My biggest issue is the Exchange org has been around and upgraded from Exchange 5.5 and it's a mess. Moving to an new domain to clean It up would never fly it took 5 years (1999 - 2004) to get on AD. I'd really like to be able to install a new Exchange server and not have it touched by all the old policies and what not sitting around from the upgraded one. MS has been through our Exchange servers and say nothing is wrong. While I would agree they work, having to uncheck on every user "Automatically update e-mail addresses based on e-mail address policy" SUCKS. We have 19 email address, depending on who/what/where you are is what you get. Also the bug in OWA for email is still a killer I think it's due to our policies though MS still says everything is fine... -----Original Message----- From: Michael B.

I've been involved in several divestitures over the years where they split the root domain controllers and each side took one. Typically, the next question is "how do I change the name of this domain?" The REAL answer is: you can't. Therefore, go ahead and plan for a forest migration now. Test it, learn your tools, get used to it. Buy something from Quest or learn ADMT really well. Regards, Michael B.

That being said, why would you want it? If you separate companies, wont you be creating a new forest and domain structure for at least one if not both companies? Since you will most likely be migrating user accounts and mailboxes to a new domain, why not either create the domain now and prepare it for migration OR leave the exchange infrastructure as-is and simple move mailboxes to servers in the domains\sites they should be in so they are ready to be moved to the new forest/domain structure. If you were thinking of just taking 2.a.com and leaving it as is at a new location, it will still look for 1.a.com and a.com. While you could most likely remove the 1.a.com references, you can't take away the references to the top level domain a.com. It sounds like it might be effort saving to meet with the folks supporting both domains and set out a long term plan for both infrastructures. hth -troy -----Original Message----- From: Martin, Jim P [mailto:jmar...@clinitech.net] Sent: Friday, January 16, 2009 12:13 PM To: MS-Exchange Admin Issues Subject: Dueling Exchange server I have been hesitant to ask but here goes. Let me lay some ground work before I get into what I'd like to do with exchange. We have a Root Domain A.com with 2 child domains 1.A.com and 2.a.com the Root domain is empty of users and only has 2 Servers in it both domain controllers for A.com. We have 2 Exchange servers in 1.A.com Exchange 2000 and Exchange 2007 with 5 Domain controllers in 1.a.com site. We have 2 Exchange servers in 2.A.com Exchange 2000 and Exchange 2007 with 5 Domain controllers in 2.a.com site. Everything works just fine there are no issues except. Some day in the next 1 - 2 years 1.A.Com and 2.A.com will become separate companies. So I've been asked if I can introduce new Exchange servers with NEW email address, to a New connection. But keep it all wrapped up in the existing AD structure. Because when we split 1 of the A.com controllers will stay with 1.a.com and 1 will stay with 2.a.com. We will just do some clean up in AD ridding ourselves of the other. 1 of the clean up tasks will be to move the MX records/users mailbox and such but when we do that we want it all on the "new" exchange server. So the question Is there a way to install a new exchange server 2007 into its own not "connecting" it to the existing Servers. I have no issues with making another site or sub domain to make it work i.e. z.1.a.com Any suggestion ---------------------------------------------------------------------------- -- This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential or privileged information.
