Here is the scenario:
Recently we upgraded our domain from NT to 2003. On the upgrade we created a new Domain Controller (Server 2) and took the old DC (Server 1) offline. We are trying to install Exchange 2003 on a new server and are not able to run forest prep. It says that it has failed to connect to the schema master on Server 2. Server 2 has been taken offline and has been removed from AD. It seems like some of the functions of the old DC (Server 1) were not transfered when we took it offline. How do we ensure that all functions are now assigned to the new DC (Server 2) so that we can install Exchange.
