Question : Configuring Exchange 2007 with mailboxes for users in a different domain

Hello,

Here's a summarily of the network environment:

We have two domains and are currently unable to establish a trust relationship:

DomainA
DC1:  Server 2003 with Exchange 2007
DC2:  Server 2000

DomainB

Server: Server 2003

We just installed Exchange 2007 on Server 2003 in DomainA and we now need to setup mailboxes for the users in DomainB.  I reconfigured both DNS servers to forward queries for each domain and I am able to ping each DC.  In DomainB I'm able to configure the trust but not validate with DomainA.  On DomainA I'm not even able to configure the trust, error: cannot find a domain controller.  I'm assuming once the domain trusts are setup I'll be one step closer but I am still unsure how I am going to setup mailboxes for the users in DomainB.  Any assistance would be GREATLY appreciated.

Thanks,

No unfortunately not.  These two network have been running in separate environments for the past three years so the best I could to was establish an domain trust.  And I thing I may have it resolved. here's what I did:

Established Two-Way trust
Created a user in DomainA identical to user in DomainB, then disabled the user account
Opened Exchange Management Console and created a link mailbox and linked it the user in DomainB
Successfully setup account in Outlook and sent and received mail
