Jim, I don't think you can have separate Exchange orgs in the single forest. 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:[email protected]] 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.
