When Microsoft introduced Windows 2000 Server, they created a family, or
series, of server operating systems. That family continues in Windows Server
2003 and consists of separate products:
• Windows Server 2003-Standard Edition
• Windows Server 2003-Enterprise Edition
• Windows Server 2003-Web Edition
• Windows Server 2003-Dafacenter Edition
• Windows Small Business Server 2003
Microsoft has also announced a 64-bit version of Windows Server 2003, which
will be available on server computers utilizing Intel’s Itanium processor or
compatible processors from other companies. Each of the three Windows
Server 2003 editions has specific capabilities designed to meet specific business
needs, and they build upon one another. In other words, Windows Enterprise
Server can do everything the standard edition can do, and more.
Windows Server 2003-Standard Edition
The standard edition of Windows Server 2003 provides all of the basic functionality a server operating system needs.The standard edition is intended to support small- to medium-sized businesses as a file server,application server or domain controller.
A file server stores files, like Microsoft Office documents and enables users to access these files over a network.
An application server runs application server software, such as a Web server or database server.
A domain controller is a special type of server that centralizes security and user accounts for a business.
Windows Server 2003 Standard Edition has the following limitations:
• A maximum of four microprocessors may be used.
• Not more than 4GB of memory is allowed. Of that 4GB, the operating system always reserves 2GB for its own use, allowing applications on the server to share the remaining 2GB.
• No games, OpenGL Screen Savers and MSN Explorer.
Windows Server 2003-Enteprise Edition
Windows Enterprise Server builds upon the Windows Server 2003 standard
edition. It provides all of the features and capabilities as the standard edition.
Enterprise Server is targeted towards medium to large businesses that need
to run extremely powerful servers, use clustering, or run especially powerful
application server software.
Benefits of Windows Server 2003-Enterprise Edition are:
• Hot add memory
• 2 to & node clustering
• Support for Intel Itanium-based computers
• Maximum memory 32 GB in X86 based processor and 64 GB in Itanium based processors.
• Microsoft Metadirectory Services (MMS)
Microsoft® Metadirectory Services (MMS) is a centralized service that stores and integrates identity information from multiple directories in an organization. The goal of a metadirectory is to provide an organization with a unified view of all known identity information about users, applications, and network resources.
Windows Server 2003-Web Edition
This version is specially designed for use as a Web server, Windows Web Server
provides a subset of the overall Windows Server 2003 functionality. The Web
Server edition is optimized for Microsoft’s Internet Information Services (IIS)
Web server platform.
Windows server 2003, web edition is a low cost, high performance front-end
Web server. Windows server 2003,web edition uses a modified kernel and
Has also been modified to ensure optimum performance for web services.
Windows server 2003, Web edition supports a maximum of two processors.
It also support physical memories of up to 2 gigabytes (GB). Windows server
2003,web edition increases system performance with built-in Network Load
Balancing.
Feature of Windows Server 2003-Web Edition :
Application Blocking
The Windows Server 2003, Web edition will prevent the loading of applications
That the Web Server license prohibits.
Domain
The Web Server 2003, Web Edition may join domains, but may not act as
Domain controllers. On Windows server 2003, Web Edition, DC Promo
Will pop up the dialog box with an error message stating that web servers
Are not licensed as domain controllers. When the dialog is dismissed, DC
Promo will exit with an appropriate exit code.
Certificate Services
Windows Server 2003 Web Edition does not support Certificate services.
Certificate services will check the product version at startup. On Windows
Server 2003, Web Edition, Certificate services will generate on error in
The event log and fail to load.
The Web Server edition does not support some advanced services, including:
i) Advanced network security feature like internet Authorization server.
ii) Fax services
iii) Terminal services
Windows Server 2003-Datacenter Edition

i) SMP scalability. Supports a minimum of eight processors with a
maximum of 32.
ii) Physical memory. Supports of physical memories of up 64 GB, 128 GB
for itinium-based computers.
Like Windows Server 2003,
Datacenter Edition includes clustering as a standard feature. Windows Server
2003, Datacenter supports cluster of eight servers
Windows Server 2003, Datacenter Edition provides optimal functionality for:
• Large data warehouses.
• Econometric analysis.
• Large-scale simulations in science and engineering.
• Online transaction processing.
• Server consolidation projects.
• Large-scale Internet service providers ( and Web site hosting.
Windows Small Business Server 2003
Windows Small Business Server 2003 provides a complete business server solution for small businesses. The integrated suite of server products enables companies to share information and resources safely and securely.
• Standard Edition includes Windows Server 2003, Standard Edition, Microsoft Windows SharePoint Services, Microsoft Exchange Server 2003, Microsoft Shared Fax Service.

2003.
Deployment Improvements
Remote Installation Service (RIS)
Windows Server 2003 now supports 64-bit Itanium Processors to perform script
based installation through RIS.
Remote Installation Services Enhancements
Remote Installation Services (RIS) enhancements include:
• Support for operating system product installations.
• More control over the answer file processing for a RIS install.
• RIS support for recovery console allows access to network files from the recovery consoles.
Answer file enhancements in Windows Server 2003
• You can encrypt system administrator password through Setup Manager
• You can Encrypt Product Key using Winnt32/encrypt
• You can now apply multiple answer files
Automated Deployment Services
Automated deployment services support an integrated set of services:
Controller Service- The Controller Service is the operational heart of ADS. The Controller orchestrates all ADS activity by providing configuration information to the other ADS services and allowing administrator inputs through the WMI interface, ADS command line tools, and a GUI MMC snap-in component.
• Network Boot Service- the Network Boot Service (NBS) works in conjunction with a network Dynamic Host Configuration Protocol (DHCP) server to give ADS boot command capability.
• Image Distribution Service- The Image Distribution Service (IDS) provides storage and communications capabilities for ADS to manage device images, and it allows administrators to deploy device operating system images created using the ADS imaging tools.
• Volume Imaging Tools- ADS has a powerful, flexible set of imaging tools. Any FAT or NTFS file system volume can be captured and deployed when used in conjunction with SYSPREP, but users get enhanced capture and editing benefits when working with NTFS based file systems.
Application Server Improvements
Application Compatibility Toolkit
Application Compatibility Toolkit includes collection of tools to determine and configure applications for functionality in a Windows 2000/XP/Server 2003 environment. Tools included in the toolkit are:
QFixApp
Allows testing of compatibility fixes one at a time.
Application Compatibility Analyzer
It provides compatibility status for applications and can assess existing applications for deployment planning.
Compatibility Administrator
It enables determination of compatibility fixes needed to support an application. Windows Application Verifier
The Windows Application Verifier tool enables tests on an application that focus on subtle issues such as heap corruptions and compatibility issues. This tool is recommended for all developers when creating applications on the Windows Operating System.
During application development, developers and testers should use the AppVerifier to detect subtle issues in their code to increase the quality of their application. The AppVerifier monitors an applications behavior in the background while it is being run, displaying this information in a log file and the debugger.
Windows System Resource Manager
WSRM is used to allocate resources among multiple applications on a server
According to business priorities.
Use Windows System Resource Manager to
• Set CPU and memory allocation policies on applications
• Manage CPU utilization
• Limit the process working set size
• Manage committed memory
• Apply policies to users or groups on a Terminal Services application platform
• Apply policies on a date/time schedule
• Generate, store, view, and export resource utilization accounting records for management, service level agreement (SEA) Tracking, and charge-back purposes
Background Intelligent Transfer Service (BITS)
Background Intelligent Transfer Service (BITS) is a background file transfer mechanism. BITS prioritizes requests, and you can use it to specify that low- priority transfers occur only when the network is not at full capacity. The transfers continue even after network disconnections or computer restarts.
You can write an application that downloads or uploads files in the background using BITS.
For example, if a user has requested that Windows Update perform multiple downloads, the Windows Update service retrieves those updates in the background by submitting a request To BITS. The BITS service then downloads the files in the background and notifies Auto Update when the files are downloaded. The requirements of BITS are atleast Microsoft Windows XP Professional or Windows Server 2003 family.
Manageability Improvements Headless Operation
A headless server is one that can be completely administered remotely and therefore does not require local keyboard, mouse or video card and monitor. Windows provides many remote management tools for use when the server is functioning, such as Telnet, administration through Terminal Services, Windows Management Instrumentation (WMI), and Windows Scripting Host.
Emergency Management Services (EMS) provides a mechanism to manage the server with no local keyboard mouse or monitor when Windows is not functional, such as when Windows is loading, a blue screen has occurred, during Setup, when the server is unavailable on a network, and during Remote Installation Services.
The administrator can use this feature to manage the remote server. An administrator ships a server to a remote site with no software installed. The technician at the remote site plugs in the server and connects the serial port to a terminal concentrator. The administrator can use this feature with Remote Installation Services feature to load and configure the software on the remote server.
Headless Server is accessed from Winnt32 command line switch (see winnt32 help) or enable it in boot.ini (this contains the settings for OSLoader in a specific section) using the command line tool bootcfg.exe (requires a reboot).
Emergency Management Services
Although you can use Emergency Management Services to manage the server remotely when the system is not functioning normally, Emergency Management Services must be set up and configured with the appropriate hardware and firmware. This is necessary so you can access the full range of its out-of-band management capabilities. When you have the proper hardware and Emergency Management Services configuration out-band console input/output (I/O) support is provided for all kernel components the loader, Setup, Recovery Console, and Stop errors.
When the server is functioning properly, support is also provided for a text-mode management console called Special Administration Console (SAC).
Components that support Emergency Management Services console redirection:
The components that support Emergency Management Services ‘console redirection include Setup, Remote installation Services, loader, and Stop error messages. When the operating sp is configured to run with Emergency Management Services, these can will redirect their output to the out- of-band management port and k the video cord, if one is attached. Emergency Management Services is available, ho with or without a video card. All Emergency Management Services output is accessible using a terminal emulator. There are also Emergency Management Services-specific versions of the Startrom.com file that is used in Remote Installation Services (RIS) installations
