121 you want to perform. These configurations are normally set when you perform a manual Exchange 2003 installation on one of your servers. Before You Begin You can run unattended setup for the following procedures:  Installing the second to nth Exchange 2003 server in your organization.  Installing Exchange 2003 System Management Tools.  Running DomainPrep. You cannot run unattended setup for the following procedures:  Installing the first Exchange Server 2003 server in your organization.  Installing Exchange Server 2003 in a Windows server cluster.  Installing Exchange Server 2003 in a mixed-mode environment (for example, Exchange 5.5 and Exchange 2003). 122  Performing any maintenance tasks (for example, adding or removing programs, re-installing Exchange, or upgrading from Exchange 2000). Procedure To use an answer file for unattended Exchange setup 1. On a server to which you want to install Exchange 2003 in unattended mode, insert the Exchange CD into your CD-ROM drive. 2. From a command prompt, type E:\setup\i386\setup /unattendfile D:\myanswerfile.ini, where E is your CD-ROM drive, D is your system drive, and myanswerfile.ini represents the name of the answer file. For More Information  For detailed steps about how to create an answer file, see How to Create an Answer File for Running Unattended Exchange Setup.  For more information about unattended setup, see Microsoft Knowledge Base article 312363, "How to use the Exchange 2000 and Exchange 2003 Installation Wizard to generate a Setup.ini file for an unattended installation," (http://go.microsoft.com/fwlink/?linkid=3052&kbid=312363). 123 How to Convert from Mixed Mode to Native Mode in Exchange An organization that is running in mixed mode can accommodate all versions of Exchange Server. An organization that is running in native mode can contain only Exchange 2000 Server or later computers; new Exchange Server 5.5 (or earlier) computers cannot be introduced into the organization. By default, Exchange 2000 Server and Exchange Server 2003 are installed in mixed mode. You can convert an Exchange organization to native mode after all of the servers are upgraded to Exchange 2000 or later, and earlier release restrictions no longer apply. You cannot switch to native mode until you either upgrade or decommission Exchange Server 5.5 (or earlier) computers. The following are some of the features of Exchange native mode:  Routing groups can consist of servers from multiple administrative groups.  Ability to move servers between routing groups.  Simple Mail Transfer Protocol (SMTP) is the default routing protocol. 124 Before You Begin Note: Before you can convert an Exchange organization from mixed mode to native mode, all of the computers in the organization must be running Exchange 2000 or later. Important: After converting the Exchange organization to native mode, you cannot change back to mixed mode. This is a one-time conversion, and you must fully understand the results before you proceed. Procedure To convert from mixed mode to native mode in Exchange 1. Open Exchange System Manager. 2. In the console tree, right-click the organization that you want to switch to native mode, and then click Properties. 125 3. In <Organization Name> Properties, under Change operation mode, click Change Mode. 4. In the warning dialog box, click Yes if you are sure that you want to permanently switch to native mode. Click Apply to accept your new Exchange mode. For More Information For more information about mixed mode and native mode for Exchange Server, see the following Microsoft Knowledge Base articles:  270143, "XADM: Mixed Mode vs. Native Mode"(http://go.microsoft.com/fwlink/?linkid=3052&kbid=270143)  327779, "How To Convert from Mixed Mode to Native Mode in Exchange"(http://go.microsoft.com/fwlink/?linkid=3052&kbid=327779)  272314, "XADM: Preparing a Mixed Mode Organization for Conversion to Native Mode"(http://go.microsoft.com/fwlink/?linkid=3052&kbid=272314) 126 How to Restart the Microsoft Exchange Information Store Service The core data storage repository for Microsoft Exchange Server 2003 is the Microsoft Exchange Information Store service, which contains both mailbox store and public folder store data. The Microsoft Exchange Information Store service uses a database engine called Extensible Storage Engine (ESE), which is a transaction-based database technology. In some troubleshooting instances or when moving from mixed to native mode, you may need to restart the Microsoft Exchange Information Store service. Procedure To restart the Microsoft Exchange Information Store service 1. On the Start menu, click Run, type services.msc, and then click OK. 2. In the Results pane, find the Microsoft Exchange Information Store service. 127 3. Right-click the service, and then click Restart.
