I want to remove one Exchange server 2010 used as DAG with HUB and Mailbox role it is installed at child domain. I have already installed other Exchange 2010 at other child domains in the same forest without problem. I wanted to start removing firts the hub role form this server and I am receiving the next error:
Hub Transport Role Prerequisites
Setup encountered a problem while validating the state of Active Directory: Exchange organization-level objects have not been created, and setup cannot create them because the local computer is not in the same domain and site as the schema master. Run setup with the /prepareAD parameter on a computer in the domain CGIXXAD and site CGXXAD, and wait for replication to complete.

The setp/pl, setup/ps,setup/p , setup/pd and setup/pad was run at the root where is the schema master located without issue and we have already installed exchange 2010 with the roles at 4 child domains but now trying to remove this server is failing with that error.
Any idea why is is failing with that error? Do I need to run again Setup.com /pd at the root. Run this setup/p again is going to affect the current exchange 2010 Servers running ok at child domain sites?
Any sugestion about this issue?
Thanks so much,
