Moving user mailbox from one domain to to the domain hosting Exchange 2010 within a forest

I have 02 domains (atco and inpro) in a forest. Users from both domains connect to exchange 2010 in atco domain. They also use atco domain email addresses. While I was able to move all mailboxes of atco domain from Exchange 2003 to Exchange 2010, I am unable to move user mailbox for inpro domain users to the new Exchange 2010. Error: Active Directory operation failed on Michael-frank.inpro.com.

On System Settings tab on Exchange 2010 only domain controllers/GCs of atco domain are shown. Exchange is probably not able to communicate with domain controller on inpro domain.

In the Event Log Event ID 2080 the in-site domain controllers are:
atcoterm.atco-intl.com
Michael-frank@inpro.com
inprodc1.inpro.com
pilot.atco-intl.com

Please find a solution to this problem. Thanks.

provide a trust between the 2 domains so exchange can communicate.

Hello,

It sounds like the schema updates were not properly applied to the inpro domain. From your schema master, logged on as an Enterprise Admin, run setup /pad from the Exchange 2010 installation media.

It is a single forest. Complete trust exists between two domains.

Should I run setup /pad on inpro.com domain controller? Secondly, will it disturb the Exchange 2010 (now in production) in any way?

You should run setup /pad on the domain controller that is the schema master. It will not disturb the current install of Exchange.

My Schema Master is a Windows 2003 SP2 Enterprise server. When I try to run setup /PAD on this machine, I get this msg: " The image file D:\setup is valid, but is for a machine type other than the current machine."

OK, do you have another DC in the same site that is running Windows 2008 or above? If so, run it from there.

I will run it on another machine hosting Windows 2008 R2 OS. That should be OK too? Pls give me time to prepare the server. Thanks.
