********************************************************************** Windows Server 2003, Standard Edition Setup Text Files, Part 2 of 4: Getting Ready for an Upgrade or a New Installation (cont.) ********************************************************************** This part of the Setup text file series can help you plan for an installation or upgrade to Microsoft Windows Server 2003, Standard Edition, in a network with one to five servers and 100 or fewer clients. The following list of headings can help you find the planning information that applies to you. For information about running Setup, see Server4.TXT. In Server1.TXT: --------------- 1.0 Upgrades Compared to New Installations 2.0 System Requirements and Hardware Compatibility 3.0 Important Files to Review 4.0 Upgrades in a Domain Containing Windows 2000 Domain Controllers In Server2.TXT: --------------- 5.0 Upgrades in a Windows NT 4.0 Domain 6.0 Decisions to Make for a New Installation 7.0 Choosing a Licensing Mode In Server3.TXT: --------------- 8.0 Deciding Whether a Computer Will Contain More Than One Operating System 9.0 Choosing a File System for the Installation Partition 10.0 Planning Disk Partitions or Volumes for New Installations 11.0 Networks: TCP/IP, IP Addresses, and Name Resolution 12.0 Deciding Between Workgroups and Domains ====================================================================== 5.0 UPGRADES IN A WINDOWS NT 4.0 DOMAIN ====================================================================== The sections that follow provide information about upgrading servers in a Windows NT 4.0 domain, that is, a domain where all domain controllers run Windows NT 4.0. The guidelines provided are for a network with one to five servers and 100 or fewer clients (the size of network discussed in this text file series). For information about upgrading servers in a domain where one or more domain controllers run Windows 2000, see "Upgrades in a Domain Containing Windows 2000 Domain Controllers" in Server1.TXT. The following list describes the sections about upgrading servers in a Windows NT 4.0 domain: * For an overview of the upgrading process, see "Stages in the Process of Upgrading Servers in a Windows NT 4.0 Domain" later in this text file. * For information about initial preparations such as checking hardware compatibility and reviewing the size of partitions on server hard disks, see "Basic Preparations for the Upgrade of Servers in a Windows NT Domain" later in this text file. * For more information about planning steps that help you tailor the upgrade to your specific situation, see the following sections later in this text file: * "Planning Server Roles and the Order of Server Upgrades from Windows NT" * "Features Available with the Upgrade of Any Server in a Windows NT Domain" * "Features Available with the First Domain Controller Upgrade in a Windows NT Domain" * "Planning DNS for the Upgrade of Domain Controllers Running Windows NT 4.0" * For more information about the final preparations to make just before beginning an upgrade, and guidelines about choices to make during the upgrade of domain controllers, see "Performing Backups and Carrying out Upgrades of Domain Controllers Running Windows NT 4.0" later in this text file. Other Sources of Information ---------------------------- For additional information, see the following sources: * For conceptual information and procedures for using Active Directory, see the Active Directory topics in Help and Support Center. You can view Help and Support Center topics on the Web at: http://www.microsoft.com/windowsserver2003/proddoc/ To view these topics on a server running Windows Server 2003, after completing Setup, click Start, and then click Help and Support. * For information about deployments and upgrades in multiple domains or in domains larger than five servers, see the Windows Server 2003 Deployment Kit. You can view the Windows Deployment and Resource Kits on the Web at: http://www.microsoft.com/reskit/ ----------------------------------------------------- 5.1 Stages in the Process of Upgrading Servers in a Windows NT 4.0 Domain ----------------------------------------------------- There are three stages to the process of upgrading servers in a domain where all the domain controllers run Windows NT 4.0: Basic preparations ------------------ There are a small number of basic preparations you must carry out before upgrading servers to a product in the Windows Server 2003 family, such as confirming hardware compatibility and reviewing the partitioning of the disks on the servers. For more information, see "Basic Preparations for the Upgrade of Servers in a Windows NT Domain" later in this text file. Planning server roles and the order in which to upgrade servers --------------------------------------------------------------- Planning server roles and the order in which to upgrade servers involves understanding the server roles available, as well as deciding when to upgrade domain controllers in relation to member servers: * The server roles available for servers running Windows NT are slightly different than for servers running Windows Server 2003. Also, in contrast with servers running Windows NT, you can change the role of a server running Windows Server 2003 without reinstalling the operating system. For more information, see "Planning Server Roles and the Order of Server Upgrades from Windows NT" later in this text file. * If the first server running Windows NT 4.0 you upgrade is a member server, many features become available immediately. For information about reasons for upgrading a particular member server early in the process, see "Features Available with the Upgrade of Any Server in a Windows NT Domain" later in this text file. * When you upgrade the primary domain controller, many Active Directory features become available (in addition to all the other features in the Windows Server 2003 family). For information about how these features can simplify administration, see "Features Available with the First Domain Controller Upgrade in a Windows NT Domain" later in this text file. However, the upgrade to Active Directory also involves some advance planning. For information about the planning necessary before upgrading to Active Directory, see "Planning DNS for the Upgrade of Domain Controllers Running Windows NT 4.0" later in this text file. IMPORTANT: When you begin the upgrade of domain controllers running Windows NT 4.0, you must upgrade the primary domain controller first. Performing backups and carrying out the upgrade process ------------------------------------------------------- There are a few preparations to make just before beginning the upgrades, such as ensuring that you have applied Service Pack 5 or later, and performing backups: * For information about the preparations to make just before beginning the upgrade, see "Applying the Service Pack, Performing Backups, and Other Preparations" later in this text file. * For information about choices to make during the upgrade of the primary domain controller, see "Running the Active Directory Installation Wizard After Upgrading the Primary Domain Controller" later in this text file. * For information on Help and Support Center topics about Active Directory, see "Learning About Active Directory After the First Server is Upgraded" later in this text file. You can also view the topics about Active Directory at: http://www.microsoft.com/windowsserver2003/proddoc/ * For guidelines regarding further upgrades, see "Completing Further Upgrades from Windows NT 4.0" later in this text file. -------------------------------------------------------- 5.2 Basic Preparations for the Upgrade of Servers in a Windows NT Domain -------------------------------------------------------- There are a small number of basic preparations you must carry out to lay the groundwork for upgrading servers in a domain where all the domain controllers run Windows NT 4.0. For information about how these preparations fit into the overall process of the upgrade, see "Stages in the Process of Upgrading Servers in a Windows NT 4.0 Domain" earlier in this text file. IMPORTANT: If you have servers or client computers that run Windows NT 3.51, it is recommended that you install or upgrade to a newer operating system on all these computers, or retire them from operation. If you have more than one domain, you must upgrade domain controllers running Windows NT 3.51 for reliable logon validation. In any case, upgrading or retiring computers running Windows NT 3.51 strengthens security and reduces the number of version differences between computers, simplifying management and troubleshooting. Compatibility check ------------------- Check to see whether the applications and hardware on your systems are compatible with products in the Windows Server 2003 family, and then update or replace them as necessary. For important details about how to do this, see "Hardware Compatibility" and "Important Files to Review" in Server1.TXT. Review partition sizes, especially on domain controllers -------------------------------------------------------- Review the partitions on the servers to make sure there is plenty of free space available for the Windows Server 2003 operating system to run. It is especially important to allow plenty of free space on domain controllers, because the existing user accounts database can expand by as much as a factor of ten when Active Directory functionality is added. For information about the disk requirements for the operating system, see "System Requirements" in Server1.TXT. Review file systems on server partitions ---------------------------------------- You must have at least one NTFS partition on domain controllers. It is recommended that you use NTFS on all partitions on all the servers in the domain, because any FAT or FAT32 partition lacks many security features. For example, on FAT or FAT32 partitions, a shared folder can be protected only by the permissions set on the shared folder, not on individual files, and there is no software protection against local access to the partition. For more information, see "Choosing a File System for the Installation Partition" and "Reformatting or Converting a Partition to Use NTFS" in Server3.TXT. Service pack ------------ Obtain Service Pack 5 or later, because it is necessary for the upgrade. Mirror sets or other disk sets ------------------------------ If you used Windows NT 4.0 to create a volume set, mirror set, stripe set, or stripe set with parity, and you want to run Setup for Windows Server 2003, Standard Edition, on that computer, you must prepare the disk set first. For details, see "Working with Volume, Mirror, or Stripe Sets or Stripe Sets with Parity" later in this text file. 5.2.1 Working with Volume, Mirror, or Stripe Sets or Stripe Sets with Parity ------------------------------------------------------------------ With the disk management technologies in Windows NT 4.0, you could create volume sets, mirror sets, stripe sets, or stripe sets with parity, each with specific capabilities and limitations. By using the dynamic disk technology introduced with Windows 2000, you can use similar technologies, with the added flexibility of being able to extend disk volumes without repartitioning or reformatting. This transition from the technologies used in Windows NT 4.0 means that you must make certain choices before running Setup for Windows Server 2003, Standard Edition. Any volume sets, mirror sets, stripe sets, or stripe sets with parity that you created with Windows NT 4.0 are not supported in Windows Server 2003, Standard Edition, although they were supported to a limited extent in Windows 2000. If you used Windows NT 4.0 to create a volume set, mirror set, stripe set, or stripe set with parity, and you want to run Setup for Windows Server 2003, Standard Edition, on that computer, you must choose one of the following methods. For a mirror set, break the mirror ---------------------------------- If you are running Windows NT 4.0 on a computer that has a mirror set and you want to run Setup for Windows Server 2003, Standard Edition, on that computer, first back up the data (as a safeguard -- the data will not be erased) and then break the mirror. Ensure that you have applied Service Pack 5 or later, required before running Setup for Windows Server 2003, Standard Edition. Then run Setup. For a volume set, stripe set, or stripe set with parity, back up the data and delete the set -------------------------------------------------------------------- If you are running Windows NT 4.0 on a computer that has a volume set, stripe set, or stripe set with parity, and you want to run Setup for Windows Server 2003, Standard Edition, on that computer, first back up the data. Next, delete the set (which will delete the data). Ensure that you have applied Service Pack 5 or later, required before running Setup for Windows Server 2003, Standard Edition. Then run Setup. After running Setup for Windows Server 2003, Standard Edition, you can make the disk dynamic, restore backed-up data as necessary, and make use of the volume options shown in the table later in this section. For more information about dynamic disks, see Help and Support Center. To open Help and Support Center, after completing Setup, click Start, and then click Help and Support. If necessary, use the Ftonline support tool ------------------------------------------- The preceding methods are the recommended methods for preparing to run Setup for Windows Server 2003, Standard Edition, on a computer that contains a volume set, mirror set, stripe set, or stripe set with parity created with Windows NT 4.0. However, if you do not use these methods and you must access one of these sets after running Setup for Windows Server 2003, Standard Edition, you can use the Ftonline tool. The Ftonline tool is part of the Windows Server 2003 family Support Tools. For more information, see topics on Support Tools and on Ftonline in Help and Support Center. To open Help and Support Center, after completing Setup, click Start, and then click Help and Support. Types of Multidisk Volumes on Dynamic Disks ------------------------------------------- The disk sets described in the previous section have different names in the Windows Server 2003 family than they had in Windows NT 4.0: ====================================================================== WINDOWS NT 4.0 NAME WINDOWS SERVER 2003 FAMILY NAME ---------------------------------------------------------------------- Volume set Spanned volume on a dynamic disk Mirror set Mirrored volume on a dynamic disk Stripe set Striped volume on a dynamic disk Stripe set with parity RAID-5 volume on a dynamic disk ----------------------------------------------------------------- 5.3 Planning Server Roles and the Order of Server Upgrades from Windows NT ----------------------------------------------------------------- This section provides a list of basic guidelines to use when planning server roles and the order of server upgrades in a domain where all the domain controllers run Windows NT 4.0. For information about how this planning fits into the overall process of the upgrade, see "Stages in the Process of Upgrading Servers in a Windows NT 4.0 Domain" earlier in this text file. Use the following guidelines when planning server roles and the order of server upgrades from Windows NT: * Familiarize yourself with the slight differences between the naming of server roles for servers running Windows NT as compared to servers running Windows Server 2003: * In Windows NT, there are two kinds of domain controllers, the primary domain controller, which is limited to one per domain and contains a read-write database, and the backup domain controller, which is not limited in number and contains a read-only database. * For domain controllers running Windows Server 2003, there is only one kind of domain controller, without a "primary" or "backup" designation. All domain controllers contain matching copies of the user accounts and other Active Directory data in a given domain, and provide read-write access to that data. * In addition to domain controllers, the possible roles for either operating system include member server, which belongs to a domain but does not contain a copy of the Active Directory data, and stand-alone server, which belongs to a workgroup instead of a domain. * Note that in contrast with Windows NT, you can change the role of a server without rerunning Setup. However, as a general practice, it is best to plan the roles ahead of time and change them only as necessary. * As was true with Windows NT, a domain must have at least one domain controller, but it is recommended that a domain have multiple domain controllers for resilience in the handling of logon requests and directory updates. * If the features you need most are not Active Directory features, you can focus on upgrading member servers first. For information about reasons for upgrading a particular member server early in the process, see "Features Available with the Upgrade of Any Server in a Windows NT Domain" later in this text file. * If the features you need most are Active Directory features, focus on upgrading domain controllers first, and carry out the advance planning that is necessary for this part of the upgrade. IMPORTANT: When you begin the upgrade of domain controllers running Windows NT 4.0, you must upgrade the primary domain controller first. For information about the features that come with Active Directory, see "Features Available with the First Domain Controller Upgrade in a Windows NT Domain" later in this text file. For information about the planning necessary before upgrading to Active Directory, see "Planning DNS for the Upgrade of Domain Controllers Running Windows NT 4.0" later in this text file. * When you begin upgrading domain controllers, if you have a remote access server that is a member server, it is recommended that you upgrade it before the last domain controller is upgraded. Such a server is dependent on domain controllers for user information, and therefore should not be "left behind" when domain controllers are upgraded. As an alternative, you can weaken the security permissions in Active Directory so that the remote access server running Windows NT can read user attributes from the domain controllers running products in the Windows Server 2003 family. For more information, see the Windows Server 2003 Deployment Kit. 5.3.1 Features Available with the Upgrade of Any Server in a Windows NT Domain ------------------------------------------------------------- If you are interested in the features in the following list, you might want to focus on upgrading the member servers in your Windows NT 4.0 domain. For information about reasons to upgrade the domain controllers, see "Features Available with the First Domain Controller Upgrade in a Windows NT Domain" later in this text file. * Management tools: Microsoft Management Console Plug and Play Device Manager Add Hardware Wizard (in Control Panel) Support for Universal Serial Bus Enhanced Backup utility * File system support: The version of NTFS in the Windows Server 2003 family includes support for disk quotas, the ability to defragment directory structures, and compressed network I/O. * Application services: Win32 Driver Model, DirectX 7.0, and Windows Script Host. * Printer protocol support: Device and protocol support allowing choices from more than 2,500 different printers. Other printing enhancements are included, for example, Internet Printing Protocol support, which allows users to print directly to a URL over an intranet or the Internet. * Scalability and availability: Improved symmetric multiprocessor support as compared to Windows NT. * Security: Encrypting File System. 5.3.2 Features Available with the First Domain Controller Upgrade in a Windows NT Domain ------------------------------------------------------------------ If you are interested in the features in the following list, all of which are features of Active Directory, focus on upgrading the primary domain controller, as opposed to member servers. (The first domain controller that you upgrade must be the primary domain controller. It is recommended that you also upgrade backup domain controllers.) For information about the DNS planning necessary before beginning the upgrade of domain controllers running Windows NT, see "Planning DNS for the Upgrade of Domain Controllers Running Windows NT 4.0" later in this text file. For information about reasons to upgrade member servers, see "Features Available with the Upgrade of Any Server in a Windows NT Domain" earlier in this text file. After running Setup, you can also display topics about Active Directory and other feature areas in Help and Support Center (click Start, and then click Help and Support). Note: When a domain controller is upgraded, it has all the features of the Windows Server 2003 family, which means it has all the features in the following list, plus the features in "Features Available with the Upgrade of Any Server in a Windows NT Domain" earlier in this text file. When you upgrade a domain controller to run a Windows Server 2003 operating system instead of Windows NT, many Active Directory features become available in the domain: * Simplified management of network-resource information and user information. * Group Policy, which you can use to set policies that apply across a given site, domain, or organizational unit in Active Directory. * Security and authentication features, including support for Kerberos V5, Secure Sockets Layer 3.0, and Transport Layer Security using X.509v3 certificates. * Directory consolidation, through which you can organize and simplify the management of users, computers, applications, and devices, and make it easier for users to find the information they want. You can take advantage of synchronization support through interfaces based on the Lightweight Directory Access Protocol (LDAP), and work with directory consolidation requirements specific to your applications. * Directory-enabled applications and infrastructure, which make it easier to configure and manage applications and other directory-enabled network components. * Scalability without complexity, a result of Active Directory scaling to millions of objects per domain and using indexing technology and advanced replication techniques to speed performance. * Use of Internet standards, including access through Lightweight Directory Access Protocol and a namespace based on the Domain Name System (DNS). * Active Directory Service Interfaces (ADSI), a powerful development environment. * Additional Active Directory features. 5.3.3 Planning DNS for the Upgrade of Domain Controllers Running Windows NT 4.0 ----------------------------------------------------------------- The Domain Name System (DNS) is a hierarchical naming system used for locating computers on the Internet and private TCP/IP networks. This section describes the planning for DNS that is recommended before you upgrade to Active Directory, that is, before you upgrade the primary domain controller in a Windows NT domain to become a domain controller running Windows Server 2003. DNS is the name resolution service used by Active Directory. Products in the Windows Server 2003 family can support both the Windows Internet Name Service (WINS) common in Windows NT networks, and DNS. You must deploy DNS to support Active Directory. You can choose to migrate from WINS to DNS or configure your new DNS infrastructure to support your current WINS infrastructure. For the upgrading of a network with one to five servers and 100 or fewer clients (which is the size of network discussed in this text file series), only a simple DNS plan is needed, because there will be no parent or child domains. (For information about upgrading networks with more than five servers, see the Windows Server 2003 Deployment Kit.) DNS names consist of name labels separated by periods. A simple DNS domain name for a Windows Server 2003 family domain could take the form domainname.ext where ext is an established "top-level domain" type such as com or org. With a domain name of that form, the form of a computer name in the domain would be: computername.domainname.ext When you upgrade the primary domain controller in a Windows NT 4.0 domain (the primary domain controller must be upgraded first, before backup domain controllers), you will be offered several different options for the handling of DNS. If there is no DNS server available to work with Active Directory, you will be offered, by default, the option of installing DNS on the domain controller you are upgrading (formerly the primary domain controller). In a network with one to five servers, the simplest approach is to accept this default. Then, after completing the upgrade of the server on which DNS was installed, take note of its static IP address, and configure other computers to send any DNS requests to that IP address. For additional basic information about DNS and how to configure it during Setup, see "Name Resolution for TCP/IP" in Server3.TXT. For more detailed information about DNS, see the Windows Deployment and Resource Kits as well as Help and Support Center. One way to view these sources of information is to work from any computer that has Internet access (regardless of the operating system running on that computer). You can view these sources of information at: http://www.microsoft.com/reskit/ http://www.microsoft.com/windowsserver2003/proddoc/ Another way to view information about DNS is to go to a computer running any product in the Windows Server 2003 family, click Start, and then click Help and Support. ------------------------------------------------------------ 5.4 Performing Backups and Carrying out Upgrades of Domain Controllers Running Windows NT 4.0 ------------------------------------------------------------ There are a few preparations to make just before beginning an upgrade from Windows NT 4.0, such as ensuring that you have applied Service Pack 5 or later, and performing backups. During the upgrade, there are a few choices to make for the upgrade of a network of two to five servers (a network within the size of those discussed in this text file series). The following sections describe these final preparations and provide guidelines for making choices. Before beginning this stage of the upgrade process, be sure to review "Basic Preparations for the Upgrade of Servers in a Windows NT Domain" and "Planning Server Roles and the Order of Server Upgrades from Windows NT" earlier in this text file. 5.4.1 Applying the Service Pack, Performing Backups, and Other Preparations --------------------------------------------------------------- Before beginning an upgrade of servers in a domain where all the domain controllers run Windows NT 4.0, apply an appropriate Service Pack, perform backups, and consider whether to remove a backup domain controller temporarily from the network: * Be sure that you have applied Service Pack 5 or later to the servers. You must apply Service Pack 5 or later before you can begin an upgrade from Windows NT 4.0. * As with any major change to the contents of hard disks on your servers, it is recommended that you back up each server before upgrading it. Also be sure to review "Preparing Your System for an Upgrade" in Server4.TXT. * If you are preparing to upgrade the primary domain controller, to protect your existing network integrity, consider removing a backup domain controller temporarily from the network. To do this, in your existing Windows NT network, choose a backup domain controller, ensure that it has a current copy of the user accounts database, and back it up. Then disconnect its network cable. After the upgrade of your primary domain controller to become a domain controller running Windows Server 2003 (you must upgrade the primary domain controller first), this disconnected system is available for promotion to a Windows NT primary domain controller if necessary. However, in the course of an uneventful upgrade, you would not and could not promote the Windows NT backup domain controller to primary domain controller. Instead, you would continue the upgrade process, eventually reconnecting the disconnected server and upgrading it. 5.4.2 Running the Active Directory Installation Wizard After Upgrading the Primary Domain Controller ------------------------------------------------------------- To upgrade the primary domain controller to become a domain controller running Windows Server 2003, you must first run Setup to upgrade the operating system. After the operating system is installed, you can run the Active Directory Installation Wizard (which appears on the screen the first time you log on). This section provides guidelines for making choices in the Active Directory Installation Wizard when upgrading the primary domain controller. For information about preparations necessary before beginning the upgrade, see "Stages in the Process of Upgrading Servers in a Windows NT 4.0 Domain" earlier in this text file. For information about starting Setup, see Server4.TXT. IMPORTANT: When you begin the upgrade of domain controllers running Windows NT 4.0, you must upgrade the primary domain controller first. The following table shows the choices that are recommended when running the Active Directory Installation Wizard on the server that was formerly the primary domain controller. These recommendations are for a network of two to five servers (a network within the size of those discussed in this text file series): ====================================================================== CHOICES ON THE SERVER RECOMMENDED ACTION FOR A NETWORK THAT WAS FORMERLY THE OF TWO TO FIVE SERVERS PRIMARY DOMAIN CONTROLLER ---------------------------------------------------------------------- Domain in a new forest Choose Domain in a new forest. or Child domain in an existing domain tree or Domain tree in an existing forest Forest functional level of Choose Windows Server 2003 interim. Windows Server 2003 interim With this domain functional level, (This choice appears only you can have domain controllers if Domain in a new forest running Windows NT 4.0 or Windows was previously selected.) Server 2003, but no domain controllers running Windows 2000. For more information, see Help and Support Center. During the upgrade, you can choose the location of three important items: the database containing user accounts and other Active Directory data, the log file, and the system volume (Sysvol) folder. The database and the log file can be on any kind of partition (FAT, FAT32, or NTFS); the database can expand by as much as a factor of ten from the size it had with Windows NT, so allow plenty of room for it. (Initially, the log file will take up very little space.) The system volume folder must be on an NTFS partition. (For information about NTFS and other file systems, see "Choosing a File System for the Installation Partition" and "Reformatting or Converting a Partition to Use NTFS" in Server3.TXT.) 5.4.3 Learning About Active Directory After the First Server is Upgraded ------------------------------------------------------------- As soon as the first server is upgraded, you can open Help and Support Center and read information about how to use Active Directory. To open Help and Support Center, click Start, and then click Help and Support. The following list provides suggestions about information to review: * Additional information about upgrading from a Windows NT 4.0 domain. * "New ways to do familiar tasks," that is, a table that compares the way you completed domain tasks with Windows NT with the way you complete those tasks with products in the Windows Server 2003 family. * Domains and forests. * Functional levels (domain functional level and forest functional level). After upgrading the last domain controller in a Windows NT domain to become a domain controller running Windows Server 2003, you have the option of changing functional levels, as described in the Active Directory topics. * The global catalog and also operations master roles, which you do not have to take action on as part of the upgrade, but might want to learn about. You can also view the same topics about Active Directory on the Web at: http://www.microsoft.com/windowsserver2003/proddoc/ For information about deployments and upgrades in multiple domains or in domains larger than five servers, see the Windows Server 2003 Deployment Kit. You can view the Windows Deployment and Resource Kits on the Web at: http://www.microsoft.com/reskit/ 5.4.4 Completing Further Upgrades from Windows NT 4.0 ------------------------------------------------------ After you upgrade your primary domain controller and ensure that it is functioning to your satisfaction, you can begin the upgrade of any backup domain controllers. (You can upgrade member servers at any time.) Upgrade the backup domain controllers one at a time (ensure that each is backed up before upgrading). Before beginning the upgrade of each backup domain controller, make sure that at least one domain controller running Windows Server 2003 is available on the network, because the user accounts and other Active Directory data will be copied from the domain controllers that have already been upgraded. Start and test each server on the network to ensure that it is functioning to your satisfaction before upgrading another backup domain controller. An upgraded domain controller will appear as a Windows NT 4.0 primary domain controller to servers and client computers running Windows NT 4.0. However, it is recommended that you complete the upgrade of all servers in the domain relatively quickly (rather than allowing a long delay). This reduces the number of version differences between computers, simplifying management and troubleshooting, and also strengthens security. If you have a remote access server that is a member server, it is recommended that you upgrade it before the last domain controller is upgraded. For more information, see "Planning Server Roles and the Order of Server Upgrades from Windows NT" earlier in this text file. ====================================================================== 6.0 DECISIONS TO MAKE FOR A NEW INSTALLATION ====================================================================== This list outlines the basic decisions to make for a new installation. What licensing mode to use -------------------------- With products in the Windows Server 2003 family, you can choose between two licensing modes: * Per Device or Per User * Per Server Per Device or Per User mode requires a separate Client Access License (CAL) for each device or user that accesses a server running a product in the Windows Server 2003 family. Per Server mode requires a separate CAL for each concurrent connection to a server. For more information about licensing, see "Choosing a Licensing Mode" later in this text file. Whether you want to be able to choose between different operating systems each time you start the computer ----------------------------------------------------------------- You can set up a computer so that each time you restart it, you can choose from several different operating systems. For more information, see "Deciding Whether a Computer Will Contain More Than One Operating System" in Server3.TXT. What file system to use on the installation partition ----------------------------------------------------- You can potentially choose among three file systems for an installation partition: NTFS, FAT, and FAT32. NTFS is strongly recommended in most situations. It is the only file system that supports Active Directory, which includes many important features such as domains and domain-based security. However, it might be necessary to have a FAT or FAT32 partition on a basic disk, if you must set up the computer so that it sometimes runs Windows Server 2003, Standard Edition, and sometimes runs Windows NT 4.0 or an earlier operating system. For more information, see "Choosing a File System for the Installation Partition" in Server3.TXT. What partition or volume you plan to install the operating system on -------------------------------------------------------------------- If you are performing a new installation, review your disk partitions or volumes before you run Setup (for an upgrade, you will use existing partitions or volumes). Both partitions and volumes divide a disk into one or more areas that can be formatted for use by one file system. Different partitions and volumes often have different drive letters (for example, C: and D:). After you run Setup, you can make adjustments to the disk configuration, as long as you do not reformat or change the partition or volume that contains the operating system. For information about planning the partitions or volumes for a new installation, see "Planning Disk Partitions or Volumes for New Installations" in Server3.TXT. How to handle IP addresses and TCP/IP name resolution ----------------------------------------------------- With TCP/IP (the protocol used on the Internet), you need to make decisions about how to handle IP addressing and name resolution (the translating of IP addresses into names that users recognize). For more information, see "Networks: TCP/IP, IP Addresses, and Name Resolution" in Server3.TXT. Whether to create domains or workgroups for your servers -------------------------------------------------------- A domain is a group of accounts and network resources that share a common directory database and set of security policies, and might have security relationships with other domains. A workgroup is a more basic grouping, intended only to help users find objects such as printers and shared folders within that group. Domains make it easier for an administrator to control access to resources and keep track of users. For more information, see "Deciding Between Workgroups and Domains" in Server3.TXT. ====================================================================== 7.0 CHOOSING A LICENSING MODE ====================================================================== Products in the Windows Server 2003 family support two licensing modes: * Per Device or Per User * Per Server If you choose the "Per Device or Per User" mode, each device or user that accesses a server running a product in the Windows Server 2003 family requires a separate Client Access License (CAL). With one CAL, a particular device or user can connect to any number of servers running products in the Windows Server 2003 family. This is the most commonly used licensing method for companies with more than one server running products in the Windows Server 2003 family. In contrast, Per Server licensing means that each concurrent connection to this server requires a separate CAL. In other words, this server can support a fixed number of connections at any one time. For example, if you select the Per Server client-licensing mode with five licenses, this server could have five concurrent connections at any one time (if each client requires one connection, this is five clients at any one time). The clients using the connections do not need any additional licenses. The Per Server licensing mode is often preferred by small companies with only one server. It is also useful for Internet or remote access servers where the client computers might not be licensed as network clients for products in the Windows Server 2003 family. You can specify a maximum number of concurrent server connections and reject any additional logon requests. If you are unsure which mode to use, choose Per Server, because you can change once from Per Server mode to Per Device or Per User mode at no cost. After you choose Per Server and complete Setup, you can display topics about licensing modes in Help and Support Center (click Start, and then click Help and Support).
