Exchange 2003 Exchange 2010 transition servicing multiple domains
Posted on 2011-10-27
I have an Exchange 2003 SP2 server running on Windows 2003 which is not a DC. I have 4 sites, each has its own domain, all four domains are in the same forest with trust relations setup. The domains are branch1.abc.com, branch2.abc.com,branch3.abc.com, branch4.abc.com. The Exchange 2003 server resides at site1 (branch1.abc.com) and houses mailboxes for the other 3 sites/domains as well. I have installed Exchange 2010 on Windows 2008 Standard R2 on a new server residing at site1 (branchh1.abc.com). I was able to move all mailboxes for the branch1.abc.com users to the Exchange 2010 server. The users are able to access their mailboxes on the Exchange 2010 server without any issues. When I try to do a local mailbox move on mailboxes who's users reside branch2.abc.com, I receive a message that says Exchange can't find a domain controller on branch2.abc.com. I receive the same message when attempting to move mailboxes on the other domains as well.
Please let me know what I need to do to be able to move all the mailboxes to the Exchange 2010 server.
