1 Istallatio 3 IN THIS CHAPTER What s New The istallatio tools ad wizards that are available for Exchage 2003 are similar to what was available i Exchage This chapter looks at usig these tools to istall Exchage from the persepectives of istallig Exchage i a ew implemetatio ad performig a iplace upgrade of Exchage. This chapter examies the prerequisites for istallig Exchage 2003 ad some of the thigs to watch out for whe istallig or upgradig Exchage servers. This icludes lookig at some ew security settigs that were slipped ito the product without a lot of fafare or otice.. Checkig istallatio prerequisites 19. Gettig ready to istall 21. Istallig Exchage 23. Upgradig Exchage 26. Automatig software istallatio 26 There are several differet methods for co-existece ad upgrades amog Exchage 5.5, 2000, ad You ll lear about these toward the ed of this chapter ad i the chapter s olie material. If you have istalled Exchage before withi your orgaizatio, this might seem a little familiar. However, if you were t ivolved i the istallatio of your Exchage servers, some of the cocepts preseted might be ew to you. Do t worry, though. The tools ad utilities provided with Exchage 2003 make istallatio as pailess as possible. Verifyig Prerequisites Before you ca begi your istallatio, you will eed to esure that you have met the prerequisites for istallig Exchage 2003 i your orgaizatio. You first looked at

2 20 CHAPTER 3 Istallatio these requiremets i Chapter 1, Itroducig Microsoft Exchage Server 2003, but here is a quick checklist to ru through before you proceed further: Is the target server part of a etwork with DNS ad WINS istalled ad cofigured? Do your domai cotroller, catalog servers, ad Active Directory ru o Widows 2000 Server SP3 or Widows Server 2003? Do you have a server that has at least a Itel Petium 133MHz or greater processor, with 256MB of RAM, 500MB of disk space, ad 200MB available o the system drive? Are the drives i the server formatted usig the NT File System (NTFS), as opposed to the FAT file system? Is the server operatig system either Widows 2000 Server SP3+ or Widows Server 2003? Have the followig compoets bee istalled ad cofigured? Iteret Iformatio Services (IIS) World Wide Web Publishig Service Simple Mail Trasfer Protocol (SMTP) service Network News Trasfer Protocol (NNTP) service NET Framework ASP.NET PREREQUISITES ON WINDOWS SERVER 2003 If you re ruig Widows Server 2003 o the computer that will hold Exchage, double-check those IIS-related prerequisites. Remember that Widows 2003 does t istall IIS or ay of its compoets by default, so you must make sure that these items are selected for istallatio. After you have verified that you have these prerequisites covered, you ca start preparig your eviromet to istall Exchage. Exchage Deploymet Tools Whe you first place your Exchage 2003 CD i your CD-ROM drive, the Exchage Server 2003 Setup splash scree (show i Figure 3.1) opes. From the iitial meu, you have access to Exchage 2003 documetatio ad the deploymet tools that are available for this versio.

3 21 Preparig for Istallatio FIGURE 3.1 Exchage 2003 Setup dialog box. These tools are similar to the tools that were available for Exchage 2000, icludig the ForestPrep ad DomaiPrep utilities ad utilities to verify the domai setup ad etwork cofiguratio. The followig sectio covers preparig to istall Exchage usig some of these utilities. Preparig for Istallatio Similar to the setup requiremets for Exchage 2000, you eed to ru the ForestPrep utility i your Active Directory Forest prior to istallig Exchage. Ruig ForestPrep The versio of ForestPrep that ships with Exchage 2003 is similar to the versio you might have used before; however, you will still eed to ru the utility to pick up chages that were made to Active Directory for this versio of Exchage. To ru the ForestPrep utility, you must be logged i to the domai as a member of the Eterprise Admiistrator ad Schema Admiistrator groups. You must also be a domai admiistrator ad have admiistrator rights o the local machie. To ru the ForestPrep utility, follow these steps: 1. From a commad prompt, ru D:\setup\i386\setup /ForestPrep (if D: is your CD-ROM drive) to ru the Exchage Istallatio Wizard. Click Next to cotiue. 2. O the Compoet Selectio page of the Istallatio Wizard, chage the actio to ForestPrep ad click Next.

4 22 CHAPTER 3 Istallatio 3. Use the dialog box show i Figure 3.2 to eter a Exchage Server admiistrator accout ad click Next to start the ForestPrep procedure. FIGURE 3.2 Exchage Server admiistrator optios. Your Active Directory structure will the be updated with the schema chages that are required to ru Exchage Server WHY BOTHER WITH FORESTPREP? Exchage Setup ca do ForestPrep for you, if ecessary. However, you ll wat to explicitly ru it yourself because ay Widows 2000 forest (or Widows 2003 forest that is ruig i the Widows 2000 fuctioal level) must rebuild all Global Catalog databases after the schema chage. That ca be a legthy process i a large forest; by explicitly ruig ForestPrep, you ca cotrol whe it happes. Ruig DomaiPrep DomaiPrep for Exchage Server 2003 is similar to its previous couterpart ad is used to prepare the domais where you pla to istall Exchage Agai, you eed to ru this utility eve if you have ru DomaiPrep for a previous Exchage istallatio. DomaiPrep creates the ecessary groups, cotaiers, ad permissios required by Exchage ad performs a preistallatio check. To ru DomaiPrep, you must be logged i as a Domai Admiistrator for the domai you are workig with. You also eed local admiistrator rights o the server where you are workig. To ru the DomaiPrep utility, follow these steps:

5 23 Creatig a New Exchage Istallatio 1. From a commad prompt, ru D:\setup\i386\setup /DomaiPrep (if D: is your CD- ROM drive) to ru the Exchage Istallatio Wizard. Click Next to cotiue. 2. O the Compoet Selectio page of the Istallatio Wizard, chage the actio to DomaiPrep ad click Next. 3. Eter a Exchage Server admiistrator accout. Click Next to start the DomaiPrep procedure, ad click Fiish whe you re doe. You eed to ru the DomaiPrep i your root domai ad every other domai where you pla to istall a Exchage 2003 server or domais where you have Mailbox-eabled objects, users, or groups. DOMAINPREP: NO BIG DEAL DomaiPrep does t icur the overhead that ForestPrep does. If you forget to ru DomaiPrep yourself, Exchage Setup hadles it, ad othig bad happes. Creatig a New Exchage Istallatio The easiest way to deploy Exchage is with a fresh ew istallatio, which is what this sectio examies. Although a fresh istallatio might ot be practical for orgaizatios that are curretly ruig Exchage, this istallatio method ca provide a good testig eviromet or serve as the base istallatio for a migratio from aother mail system. MIGRATING FROM EXCHANGE 2000 If you are ruig Exchage 2000 ad wat to upgrade to Exchage 2003, see Upgradig from Exchage 2000, page 26. To create a ew Exchage istallatio, you eed to esure that you have met all the prerequisites listed earlier ad that you have a server (or servers) that meets the miimum requiremets as set out i Chapter 2, Architecture. You must be logged i to the domai as a user who has Exchage Full Admiistrator privileges at the orgaizatioal level. You also eed to be set up as the local admiistrator o the server where you wat to istall Exchage. SECURITY CHANGES Somethig ew with Exchage 2003 is that it is oly the first Exchage server that eeds to be set up by a user who has Exchage Full Admiistrator privileges at the orgaizatioal level. To istall additioal servers, the user oly eeds to have Exchage Full Admiistrator privileges at the admiistrative group level.

6 24 CHAPTER 3 Istallatio The followig sectio details how to istall Exchage o the first server i your plaed topology. To istall additioal servers, you would follow the same steps, except istead of creatig a ew Exchage orgaizatio, you would simply joi a existig Exchage orgaizatio. To istall your first (ad subsequet) Exchage servers, follow these steps: 1. From a commad prompt, ru D:\setup\i386\setup (where D: is your CD-ROM drive) to ru the Exchage Istallatio Wizard. Click Next to cotiue after each step. 2. Accept the licese agreemet ad eter your Exchage product key. 3. Usig the Compoet Selectio dialog box show i Figure 3.3, select the Exchage compoets you wat to istall by chagig the drop-dow list to Istall. FIGURE 3.3 Compoet selectio. 4. I the Istallatio Type dialog box, select the optio to Create a New Exchage Orgaizatio. 5. Eter a ew ame for your orgaizatio by usig a combiatio of letters, umbers, spaces, dashes, or hyphes. 6. Verify the compoets you wat to istall by usig the dialog box show i Figure 3.4. Accept the fial licese agreemet ad click Fiish at the ed of the Istallatio Wizard. This begis istallatio of the compoets you selected earlier. Whe the istallatio is fiished, a Microsoft Exchage program group is added to the Start meu with the tools you use to cofigure ad maage Exchage. (You will look at these tools i Chapter 4, Cofiguratio. )

7 25 Creatig a New Exchage Istallatio FIGURE 3.4 Compoet cofirmatio. CONCURRENT INSTALLATIONS If you are plaig to istall multiple Exchage servers at oce (for disaster recovery or to decrease dowtime), Exchage 2003 has a special switch that you ca use to esure that the istallatios ca ru cocurretly. Whe you re followig the previous steps, ru SETUP by usig the /ChooseDC switch to eter the domai ame of a specific Active Directory domai cotroller. This eables you to force all the servers to commuicate with the same domai cotroller ad elimiate problems experieced whe istallig cocurretly usig Exchage If you would like to cofirm that the istallatio completed successfully, the Exchage Istallatio Wizard geerates a log file that is available i the C: drive of the server where you istalled Exchage. This log file, show i Figure 3.5, displays a ruig commetary o the istallatio process. At the ed of the log, the commetary should idicate whether Exchage was istalled successfully. EVENT VIEWER You ca fid more iformatio about the istallatio process i the Widows Evet Viewer, which provides etries i the applicatio log that relate to the istallatio of Exchage compoets. With Exchage istalled, you are ready to cofigure your server, which is covered i the ext chapter.

Upgradig from Exchage 2000 If you have picked up this book, chaces are that you are already ruig Exchage 2000 withi your orgaizatio ad wat to upgrade this implemetatio to Exchage This sectio covers how to perform a i-place upgrade o the existig Exchage servers withi your orgaizatio, startig with some compoets that are o loger part of Exchage ad eed to be removed before you ca proceed. Before you ca upgrade from Exchage 2000 to Exchage 2003, you eed to remove some compoets that have bee phased out betwee versios. These iclude the followig: Mobile Iformatio Server Exchage Evet Source Exchage 2000 Istat Messagig Server Exchage 2000 Chat Service Exchage 2000 Coferecig Server Exchage 2000 Coectors (Lotus Notes, MS Mail, ad so o) To remove these compoets, use the Add/Remove optios uder the Cotrol Pael. You ca remove the compoets that are related to Exchage 2000 through the Exchage 2000 maiteace program available i the Add/Remove Compoets cosole. You ca fid the Mobile

9 27 Upgradig from Exchage 2000 Iformatio Server compoet uder the maiteace program for Mobile Iformatio Server 2002, also foud i the Add/Remove cosole. FORCED INSTALLATION OF ASP.NET If you are ruig Widows 2000, the Exchage setup program automatically forces a istallatio of the.net Framework ad ASP.NET whe you istall Exchage. With those compoets removed, you eed to go through the prerequisite checklist discussed earlier i this chapter. Specifically, if your Exchage 2000 servers are ruig o Widows 2000 Server, you eed to make sure that these servers have bee updated to Service Pack 3 or greater. I additio, you should be ruig Exchage Server 2000 Service Pack 3 or greater. WEB RESOURCE This sectio of the chapter covers upgradig from Exchage For iformatio o upgradig from Exchage 5.5, go to the Delta Guide series Web site at deltaguideseries.com ad eter article ID A Before you begi the upgrade procedures detailed ext, make sure that you have a full backup of your Exchage istallatio. Ru through the upgrade process i a testig eviromet prior to upgradig a productio system. This ca help you idetify issues that might arise later ad save you the hassle of tryig to troubleshoot a upgrade while it is occurrig. UPGRADE ORDER Whe you re selectig servers to upgrade, it is best to perform a i-place upgrade o your frot-ed servers prior to upgradig back-ed compoets. You must remove ay tuig settigs that you have made to your Exchage 2000 servers. Most of these settigs ad optios have bee icorporated ito Exchage 2003 or are o loger required. These tuig settigs have geerally take the form of chages to Exchage registry settigs. For a list of these tuig settigs, visit the Microsoft Support Web site at ad search for Exchage 2003 Deploymet Guide.

10 28 CHAPTER 3 Istallatio To perform a i-place upgrade of a existig Exchage 2000 server, follow these steps: 1. From a commad prompt, ru D:\setup\i386\setup (where D: is your CD-ROM drive) to ru the Exchage Istallatio Wizard. Click Next to cotiue after each step. 2. Accept the licese agreemet ad eter your Exchage product key. 3. Usig the Compoet Selectio dialog box show i Figure 3.6, select the Exchage compoets you wat to istall by chagig the drop-dow list to Upgrade. FIGURE 3.6 Compoet upgrade optios. 4. Verify the compoets you wat to istall ad click Fiish at the ed of the Istallatio Wizard to start istallatio of the compoets you selected earlier. SECURITY CHANGES Oe chage that admiistrators will otice immediately whe they upgrade from Exchage 2000 is that they ca o loger ope aother user s Mailbox by default. Uatteded Istallatio I additio to the atteded istallatios you have explored up to this poit, Exchage ca be istalled i a Uatteded mode, where a aswer file provides the aswers ad selects the optios that a user would ormally iteractively select i the Exchage Istallatio Wizard.

11 29 Uatteded Istallatio This feature ca come i hady whe you have may Exchage servers to istall or for disaster recovery whe you eed to istall multiple Exchage servers quickly. It s importat to ote that you caot use this istallatio method to istall the first Exchage server i your orgaizatio. This method is oly valid for servers that are added to your orgaizatio after the first server is istalled ad cofigured. If you pla to cluster your Exchage servers, you caot use a uatteded istallatio. Likewise, you caot employ this method i Exchage implemetatios that mix Exchage versios or for upgradig Exchage 2000 servers (which would have bee a ice feature to have for this release.) To perform a uatteded istallatio, you first eed to create a aswer file that cotais iformatio o all the compoets ad settigs for subsequet istalls. To create a aswer file to use with a uatteded setup ad lauch a uatteded setup usig this file, follow these steps: 1. From a commad prompt, ru D:\setup\i386\setup /createuatted C:\aswers.ii (if D: is your CD-ROM drive ad C:\aswers.ii is the locatio ad fileame of the aswer file you wat to create). This lauches the Exchage Istallatio Wizard. Cotiue the istallatio as you ormally would, clickig Next to cotiue after each step. 2. Accept the licese agreemet ad eter your Exchage product key. 3. Usig the Compoet Selectio dialog box, select the Exchage compoets you wat to istall by chagig the drop-dow list to Istall. 4. Verify the compoets you wat to istall, accept the fial licese agreemet, ad click Fiish at the ed of the Istallatio Wizard to start istallatio of the compoets you selected earlier. 5. Copy your aswer file to the server where you wat to istall Exchage i uatteded mode. 6. From a commad prompt, ru D:\setup\i386\setup /uattedfile C:\aswers.ii (if D: is your CD-ROM drive ad C:\aswers.ii is the locatio ad fileame of the aswer file you just created). This lauches the Exchage istallatio process i Silet mode; the user will ot be prompted for settigs or optios. You ca the use the stadard logs ad evets to determie the outcome of the istallatio as you would with a ormal, atteded Exchage istallatio. With the actual istallatio out of the way, you ca move o to cofigurig your ew Exchage server, which is covered i the ext chapter.
