I have a member 2003 server in a primary domain controller and I can not get Exchange to install. I get the following error when running a domain prep:D:\>setup /PrepareAD /OrganizationName:northern-pharmacyWelcome to Microsoft Exchange Server 2007 Unattended SetupPreparing Exchange SetupNo server roles will be installedPerforming Microsoft Exchange Server Prerequisite Check Organization Checks ......................... FAILED Setup needs to contact the Active Directory schema master but this computeris not in the same Active Directory domain as the schema master (DC=northernpharmacy,DC=com). 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 northernpharmacy and site Northern-Pharmacy, and wait for replication to complete.The Exchange Server setup operation did not complete. Visit http://support.microsoft.com and enter the Error ID to find more information.Exchange Server setup encountered an error.I also get the following error when running the setup inside the child domain. I can ping the primary domain by DNS name but Exchange 07 will not install. Here is the error I get:Event Type: ErrorEvent Source: MSExchange ADAccessEvent Category: DevicesEvent ID: 2152Date: 5/18/2008Time: 11:00:23 AMUser: N/AComputer: EXCHANGE07Description:The description for Event ID ( 2152 ) in Source ( MSExchange ADAccess ) cannot be found.

The following information is part of the event: ExSetupUI.exe, 1428, 1753, Error 6d9 from HrGetServersForRole.How do I get this member server to work so I can install Exchange 07?? Can I run a domain prep off of the exchange 2003 cd?? Any help would be greatly appreciated.
