I am trying to consolidate two domains into a single Windows 2003 domain. Currently, our network consists of two seperate domains, let�s call them DomainA (a Windows 2003 domain native 2000 mode) and DomainB (a Windows NT4 domain). DomainA is in New York and DomainB is in Texas; a VPN connects them. DomainA has was upgraded from NT 4 and Exchange 5.5 to Windows 2003 and Exchange 2003. I want to consolidate all of my mailboxes to DomainA (Exchange 2003) and remove DomainB from the network.

Here are the facts:

*DomainA and DomainB are connected by a two way trust.

*Both Exchange servers were installed using the same Exchange Organization name �MyCompany� and handle the email for "Mycompany.com". At the time of install the two servers were not connected via a VPN. (Directory replication over SMTP was used to keep the directory in sync)

*The Exchange server in DomainA was created in the Exchange site �SiteA� and the Exchange Server in DomainB was created in the Exchange site �SiteB�.

*Disabled accounts for all of the mailboxes in Domain B have already been populated in active directory on DomainA using ADC connection aggreements, but it looks like these accounts still depend on Domain B.

*I am able to move mailboxes from the Exchange 5.5 server in Domain B to the Exchange 2003 server in DomainA using "Exchange tasks --> Move mailbox --> Cross administrative group" .

I need to migrate all of the accounts to DomainA and remove Domain B from the network all together. How can I migrate the user login accounts as well, so that I can rehome these mailboxes to the DomainA login IDs and remove DomainB all together.? In additiion, are there any other system settings that need to be moved?
