We upgraded from Exchange 2000 to Exchange 2007 this past summer. We are now trying to install SP1 but have run into some difficulty. When attempting to run the install we receive the following: Setup needs to contact the Active Directory schema master but this computer is not in the same Active Directory site as the schema master (CorporateServices). Each remote office has their own site. From the command prompt, if we use the /dc parameter and specify the Domain Controller at Corporate will this be enough? Or is there domain prep work (other than what we did when we went from 2000-2007) that needs done? Thanks

Have you been able to install SP1 yet? I am having the same issue.

Did you find any solution yet? I am facing the same problem.
