SYMPTOMS
After you prepare your Microsoft Active Directory directory service domain for an Exchange Server 2003 installation by using the /forestprep and /domainprep commands you can successfully run the Exchange 2000 /forestprep and /domainprepcommands on the same domain. You are then able to install Exchange 2000 on a domain controller, but you are not prompted to join an existing site or to create a new site. A new organization name in the form of a globally unique identifier (GUID) is automatically assigned to the new organization.



RESOLUTION
To resolve this problem, follow this procedure:


 * 1) Remove Exchange 2000.
 * 2) Run Exchange Server 2003 Setup by using the /removeorg switch to remove the organization created by Exchange Server 2000 Setup.
 * 3) Run Exchange 2003 by using the /forestprep switch to update the Active Directory for Exchange Server 2003.
 * 4) Install an Exchange Server 2003 computer as the first server in the new organization by naming the organization (by using the name that you want).
 * 5) Add any required Exchange 2000 servers to the organization.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
