The new Web edition was a much-scaled-back version of the Windows
Server product and aimed at combating the trend of using free Linux-
based services for hosting web sites.
You might run Windows 2000 servers today, so the following list covers
the new features of Windows 2003. These features carried into Windows
Server 2008, so they are still reasons to migrate to the latest server OS.
■
The Microsoft .NET Framework became a core part of the OS.
■
New Active Directory features provided prune and graft functional-
ity, allowing you to move and rename domains within an Active
Directory forest.
■
Domain controllers were added via a system state backup of anoth-
er domain controller, instead of copying all domain information over
the network.
■
Internet Information Services (IIS) 6.0 offered improved security
with its default state of lockdown and new management features.
IIS 6.0 also featured improved reliability and allowed consolidation
where appropriate.
■
Updated Terminal Services allowed access to and control of the
server console via the
/console
switch of the mstsc application.
■
Virtual Disk Service (VDS) provided single interface for disk man-
agement.
■
Volume Shadow Copy Service (VSS) allowed point-in-time copies of

content of the service pack is stored locally on the server to ensure that the
newest code is always used.
Microsoft continued to add new features to Windows 2003 via down-
loadable feature packs. Major new features were not made available in
service packs due to past complications, so feature packs were a great com-
promise. Users who didn’t want to wait for the next major release could get
features as Microsoft released them. Other users were free from installing
features they did not want and that could introduce complexity or poten-
tial security considerations. Feature packs available for download include
the following:
■
Active Directory Application Mode (ADAM). Active Directory
“lite,” enabling multiple directories to exist on a single Windows
2003 or XP machine without the full infrastructure of DNS and
other components normally required for a domain. ADAM stores
data related to an application that does not require the availability
associated with data stored in an AD-based domain.
■
Group Policy Management Console (GPMC). Enables policy
backup and restoration of policies, task scripting, better manage-
ment, and HTML reports.
■
Identity Integration Feature Pack (IIFP). Allows replication
among AD, ADAM, and Exchange directory service (2000 and
2003). This is useful in multiforest situations to sync the Global
Address List (GAL). IIFP is MS Identity Integration Server (MIIS)
lite!
■
ISCSI support. Enables IP-based storage area network (SAN) con-
nectivity via the Internet Small Computer System Interface (iSCSI).

Windows SharePoint Services (WSS) update. Improved
SharePoint capabilities and security.
■
Windows Automated Installation Kit. Contains tools and infor-
mation for the deployment of Windows Vista from a Windows
2003–based infrastructure including Windows Deployment
Services (WDS), which replaces Remote Installation Service (RIS)
and forms a core part of Windows Server 2008.
R2 on Disk 2, R2D2
At the end of 2005, Microsoft started a new tradition, releasing Windows
2003 R2 (short for Release 2). There are two important factors for this R2
release:
■
Windows 2003 R2 is Windows 2003 with Service Pack 1 built in.
■
It has no new kernel changes or modifications to the core OS. The
R2 relates to a second supplied CD that contains new features orig-
inally slated for and built in to the Windows Server 2008 OS.
R2 releases will be seen in other products in the Microsoft line.
Windows 2003 R2 comprises two CDs: the first CD contains Windows
2003 with SP1, and the second contains the new content. After installation
of the first disc, the installer prompts the user to insert the second CD. If
a server is already running Windows 2003 SP1, only the second CD has to
be inserted.
The only actual change made to the core OS is that a new version of
the MMC (3.0) is installed before the second CD is executed and new fea-
tures are added. The new version of the MMC allows for new functionali-
ty provided by the updated management console, which some of the R2
component snap-ins require. Add/Remove Programs is updated to allow
for the installation of the new R2 components, and the Manage/Configure

ferent scenarios. A new Print Management Console allows a cen-
tralized view and management of printers in distributed environ-
ments, allowing centralized driver upgrades, printer discovery on
remote subnets, form configuration, and notification options if a
printer becomes unavailable, which includes executing a script or
sending an e-mail.
■
Active Directory Federated Services (AD FS) extends the visibility
of a trusted organization’s directory service to allow its users access to
Web-based applications in another organization. For detailed infor-
mation, see www.windowsitpro.com/Windows/Article/ArticleID/
48252/48252.html.
■
WSS SP2 is .NET 2.0–compatible and certified to run on 64-bit. (It
is 32-bit code but is certified to run in Windows on the Windows
subsystem that 64-bit OSs use to run 32-bit code.) SharePoint
Services SP2 supports Kerberos authentication and fully integrates
with Windows (now shows as a Server role and in Add/Remove
Windows Components).
Add all R2 components as entries in the Windows Components
dialog.

■
A new Quota Management component comprising three technolo-
gies. One component is a new quota system based on the physical
space (rather than logical size) used on a disk. If users compress
files, they store more data, which was not the case in a logical size
quota. The quotas can be set on a folder or disk level, so you can
configure a specific folder not to exceed 500MB. A file-screening
component allows for real-time file type checking. If a type of file
tries to write to a folder that has a rule stopping that type, an I/O
error generates and the file write stops. One useful scenario for this
technology is for blocking video/audio files to company file shares.
For both quotas and file screening, comprehensive actions occur
when a user attempts to breach policy. Actions could include e-mail-
ing the offender, e-mailing an administrator/manager, and perform-
ing an action. Storage reports are the third technology, providing
detailed reports of file system status in a variety of formats.
Why put out an R2 release? Microsoft already set a precedent with fea-
ture packs that added functionality to the Windows 2003 product as free
downloads from the Microsoft site, so why not just have the R2 features
provided as downloads as separate feature packs? There are two trains of
thought on this issue. It’s important to realize that Windows 2003 R2 is a
separate product; there is no upgrade version or free update. You have to
