 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.

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

Server, see the following Microsoft Knowledge Base articles:

Mode"(

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.
