Microsoft Exchange Server 2003 Deployment Guide- P35 doc

Note: An account that has the Exchange Full Administrator role applied at the administrative group level can run Exchange Setup on a cluster node if the cluster node is a member of the

Area Requirements

Permissions Account must be a member of a

group that has the Exchange Full Administrator role applied at the organization level

Note:

An account that has the Exchange Full Administrator role applied at the administrative group level can run Exchange Setup on a cluster node if the cluster node is a member of the Exchange Domain Servers group on the domain to which the cluster node belongs

When you install Exchange Server 2003 into an existing Exchange Server 5.5 organization, additional permissions are required For information about the specific permissions that are required to install Exchange Server 2003 into

an existing Exchange Server 5.5

File system  Installation drive cannot be the

cluster shared drive

 Installation drive must be the same across all nodes

one of the nodes in the cluster The clustered MSDTC resource should exist in the default cluster group

Other  The fully qualified domain name

(FQDN) of the node cannot match the Simple Mail Transfer Protocol (SMTP) proxy domain of any recipient policy

Note:

A cluster with three or more nodes is usually active/passive

In active/passive mode, there

can be n – 1 or fewer Exchange Virtual Servers, where n is the

number of nodes For example,

if, by installing Exchange on a node, the cluster becomes a three-node cluster, and the number of Exchange Virtual Servers is three or more, then Exchange Setup stops

installation until you remove one

of the Exchange Virtual Servers

 The Cluster service must be initialized and running

If running Windows 2000 Windows 2000 Service Pack 4

(SP4) is required

 To obtain Windows 2000 SP4, see the Windows 2000 Service Packs Web site

Ensuring That the Cluster Service is Running on Each Node

To successfully install Exchange Server 2003 on a server in a cluster, the Cluster service must be installed and running on a cluster node The

Cluster service is installed by default with Windows Server 2003,

Enterprise Edition and Windows Server 2003, Datacenter Edition

However, the Cluster service is not installed by default with

Windows 2000 Server

Installing and Enabling Required Windows Services

Exchange Server 2003 Setup requires that the following components and services be installed and enabled on the server:

 NET Framework

 ASP.NET

 Internet Information Services (IIS)

 World Wide Web Publishing Service

 Simple Mail Transfer Protocol (SMTP) service

 Network News Transfer Protocol (NNTP) service

If you are installing Exchange Server 2003 on a server running

Windows 2000, Exchange Setup installs the Microsoft NET Framework

Important:

When you install Exchange on a new server, only the required services are enabled For example, the Post Office Protocol version3 (POP3)

and Internet Message Access Protocol version4 (IMAP4) services are disabled by default on all of your Exchange Server 2003 servers You should only enable services that are essential for performing

Exchange Server 2003 tasks The NNTP service should always remain disabled Although NNTP is required in order to install Exchange,

Exchange NNTP features are not supported and cannot be used on

clustered Exchange servers

For detailed steps about how to install and enable the IIS prerequisites for Exchange cluster running on Windows 2000, see How to Install IIS

For detailed steps about how to install and enable the IIS prerequisites for

an Exchange cluster running on Windows Server 2003, see How to Install

Server 2003 or Windows 2000, you must first install the Microsoft

Distributed Transaction Coordinator (MSDTC) resource into the cluster

It is an Exchange best practice to install the MSDTC resource into the default cluster group However, the MSDTC resource is the only resource supported in the default cluster group Exchange resources should not be added to the default cluster group, as that configuration is not supported

For detailed steps about how to install the MSDTC in a Windows 2000 server cluster, see How to Install the Microsoft Distributed Transaction

For detailed steps about how to install the MSDTC in a Windows Server

2003 server cluster, see How to Install the Microsoft Distributed

For more information about adding the MSDTC resource in Windows Server 2003, see Microsoft Knowledge Base article 301600, "How to Configure Microsoft Distributed Transaction Coordinator on a Windows Server 2003 Cluster"

"How to enable network DTC access in Windows Server 2003"

Exchange Server security best practice to not enable network DTC

access for an Exchange cluster If you are configuring the Distributed Transaction Coordinator resource for an Exchange cluster, do not

enable network DTC access

Running Exchange Setup

Installing Exchange Server 2003 on a cluster is similar to installing

Exchange Server 2003 on non-clustered servers For detailed steps

Note:

Unattended Setup is not supported when installing Exchange

Server 2003 on a Windows cluster

Before installing Exchange Server 2003 on a node, it is recommended that you move all cluster resources owned by the node to another node

Important:

Install Exchange Server 2003 completely on one node before you

install it on another node

For important information about post-deployment steps, see

information about how to verify that your Exchange installation was

successful It also includes information about how to upgrade your cluster with the latest Exchange Server 2003 service packs and security patches
