Steps to install Small Business Server 2003 in an existing Active Directory domain

To install a SBS 2003 computer in an existing Active Directory domain, follow these steps:

1. On a Windows 2000 domain, you must prepare Active Directory before you install the SBS 2003 computer in the domain. For more information about how to install a Windows Server 2003 domain controller into an existing Windows 2000 forest, click the following article number to view the article in the Microsoft Knowledge Base:(http://support.microsoft.com/kb/278875/ ) Dcpromo.exe and Winnt32.exe log errors when you create a Windows Server 2003 domain controller in a Windows 2000 domain or forest or when you upgrade a Windows 2000 domain controller that resides in a Windows 2000 forest to Windows Server 2003
2. Start the installation of SBS 2003 by inserting CD 1 into the CD or DVD drive.
3. When the operating system is installed and the computer restarts and continues with the integrated Setup program, click Cancel to stop the integrated Setup program.
   
4. On the SBS 2003 computer, configure a static IP address on the network card and make sure to configure DNS to include the existing server that hosts the Active Directory zone.
   
5. Note Do not create a new forest and do not create a child domain.
   1. Click Start, click Run, type dcpromo, and then click OK.
   2. Click Next two times.
   3. Click Additional Domain Controller for an existing domain, and then click Next.
   4. Enter the credentials for the domain administrator account, and then click Next.
   5. In the Domain name area, type the FQDN for the Active Directory domain namespace that you want to join, and then click Next. For example, type contoso.local. If you are not sure of the FQDN, you can click Browse to select the correct domain.
   6. Click Next to accept the default locations for the Database and Log folders.
   7. Click Next to accept the default locations for the shared system volume.
      
   8. Type the Directory Services Restore Mode administrator password, and then click Next.
      
   9. On the Summary screen, click Next to start the Dcpromo.exe program. This process may take several minutes.
   10. Click Finish to complete the Dcpromo.exe program, and then click Restart Now.
   11. Log on to the computer after it restarts and confirm that the computer has been successfully promoted to a domain controller. To do this, click Start, click Run, type cmd, and then click OK.
   12. At the command prompt, type gettype, and then press ENTER. The output should read as follows:
       
       

       Host Name: ServerNameName: Windows Server 2003 for Small Business Server
       Version: 5.2 Build 3790

   2. Click Add/Remove Windows Components.
   3. In the Windows Components list, double-click Networking Services.
   4. Click to select the Domain Name System (DNS) check box, and then click OK.
   5. Click Next, and then click Finish.
      
   
   
7. Promote the SBS 2003 computer to a global catalog server. To do this, follow these steps:
   1. Click Start, point to Administrative Tools, and then click Active Directory Sites and Services.

   5. Restart the computer.
      
      Note Do not restart the computer or remove any other global catalog servers until you receive event 1119 or 1869. If you do this, it will cause adverse effects as there will be no global catalog servers available to process requests.
8. After the new computer is successfully promoted to a global catalog server, remove any other global catalog servers in the domain. To do this, follow these steps:
   1. Click Start, point to Administrative Tools, and then click Active Directory Sites and Services.
   2. In the console pane, expand Sites, and then expand Default-First-Site-Name.

11. Wait for the new Active Directory objects to replicate to the SBS 2003 computer. The time this takes depends on the Active Directory size and on network performance. You can view the Directory Service event log to verify that replication has completed successfully. The SBS 2003 integrated Setup program may not continue if replication has not completed or if replication has failed.
    
    To test replication, you can create a new test user on a domain controller and after several minutes confirm the object has been replicated to the SBS 2003 computer. You can also force replication from a domain controller. To do this:
    1. On the SBS 2003 computer, click Start, point to Administrative Tools, and then click Active Directory Sites and Services.
    2. In the left pane, expand Default-First-Site-Name, expand Servers, and then expand the domain controller that you want to replicate from.
    3. Click NTDS Settings. One or more objects are listed in the right pane. One of those objects is a link to the domain controller you want to replicate from. To see the "friendly" name of the object, right-click the object and view the name. Right-click the domain controller object, and then click Replicate Now. The replication is performed immediately.
12. Change the DNS settings on all domain controllers to point to the new SBS 2003 computer as the primary DNS server. To do this, follow these steps.
    
    Note Follow these steps on all domain controllers in the Active Directory, including the SBS 2003 computer.
    1. Click Start, point to Control Panel, point to Network Connections, right-click the internal network connection, and then click Properties.
    2. Click to select Internet Protocol (TCP/IP), and then click Properties.
    3. Change the preferred DNS server. Type the IP address of the SBS 2003 computer as the preferred DNS server. Also, make this change on the SBS 2003 computer.
       
       Note The alternative DNS server can point to the previous preferred DNS server as long as it is a server that hosts the Active Directory zone.
13. On the SBS 2003 computer, insert the SBS 2003 CD 1 into the CD or DVD drive and continue with the integrated Setup of SBS 2003 and its components.
14. If you already have Microsoft Exchange Server installed in the organization, the integrated Setup installs Exchange Server into the existing organization. If you already have an Exchange 2003 Server or an Exchange 2000 Server in your organization, and you plan to retire that Exchange Server, you can move the mailboxes and public folders to the new Exchange 2003 Server before you retire the old Exchange Server.

    5. Double-click each entry, and then enter the name of the new Exchange Server that is running on the SBS 2003 computer in the Exchange server area.
    6. Expand Administrative Groups, expand Administrative Group Name, expand Routing Groups, and then expand First Routing Group.
    7. Click Connectors, right-click your SMTP connector if it is present, change the server that is listed in the Local bridgeheads area to the new SBS 2003 computer, and then click OK.
    8. In the left pane, under First Routing Group, click Members.
    9. In the right pane, right-click the new SBS 2003 computer, and then click Set as Master.
    10. In the left pane, expand Administrative Groups, expand Administrative Group Name, expand Servers, and then expand the Exchange Server that existed before you added the new Exchange Server on the SBS 2003 computer.
    11. Expand First Storage Group, expand Mailbox Store, and then click Mailboxes.
    12. Select all the mailboxes, right-click the mailboxes, and then click Exchange Tasks.
    13. In the Exchange Task Wizard, click Move Mailbox, and then click Next.
    14. Click to select the new SBS 2003 computer in the Server list, and then click Next.
    15. Specify how you want the Move Mailbox procedure to handle corrupted messages, and then click Next two times to re-home all the mailboxes to the new SBS 2003 computer.
        
        Note This procedure also re-homes the public folders to the new SBS 2003 computer.
    16. Click Finish.
    17. As soon as replication is successful, remove Exchange Server from the computer that is to be retired. If the computer that is to be retired is also a domain controller, run the Dcpromo.exe program to remove this computer from the domain before you physically retire it.
        
        Note You must instruct all Exchange Server users to point to the new Exchange Server.
15. Run the Dcpromo.exe program on the SBS 2003 computer to join the existing domain.
