1. Roles of Window Server 2008R2

2. Active Directory Certificate Services
• Active Directory Certificate Services Active Directory Certificate
Services (AD CS) provides customizable services for issuing and
managing certificates in software security systems that use public
key technologies. You can use AD CS to create one or more
certification authorities (CA) to receive certificate requests, verify
the information in the requests and the identity of the requester,
issue certificates, revoke certificates, and publish certificate
revocation data.
• Applications supported by Active Directory Certificate Services
include Secure/Multipurpose Internet Mail Extensions (S/MIME),
secure wireless networks, virtual private networks (VPN), IP security
(IPSec), Encrypting File System (EFS), smart card logon, Secure
Socket Layer/Transport Layer Security (SSL/TLS), and digital
signatures.

3. Active Directory Domain Services
• Active Directory Domain Services (AD DS) stores
information about users, computers, and other
devices on the network. AD DS helps
administrators securely manage this information
and facilitates resource sharing and collaboration
between users. AD DS is also required to be
installed on the network in order to install
directory-enabled applications such as Microsoft
Exchange Server and for applying other
Windows Server technologies such as Group
Policy.

4. Active Directory Federation Services
• Active Directory Federation Services (AD FS)
provides Web single-sign-on (SSO)
technologies to authenticate a user to
multiple Web applications that use a single
user account. AD FS accomplishes this by
securely federating, or sharing, user identities
and permissions, in the form of digital claims,
between partner organizations.

5. Active Directory Lightweight Directory Services
• Organizations that have applications which
require a directory for storing application data
can use Active Directory Lightweight Directory
Services (AD LDS) as the data store. AD LDS runs
as a non-operating-system service. Therefore,
AD LDS does not require deployment on a
domain controller. Running as a non-operating-
system service allows multiple instances of
AD LDS to run at the same time on a single server,
and each instance can be configured
independently for servicing multiple applications.

6. Active Directory Rights Management Services (AD RMS)
• Active Directory Rights Management Services is
information protection technology that works with
AD RMS -enabled applications to help safeguard digital
information from unauthorized use. Content owners
can define exactly how a recipient can use the
information, such as who can open, change, print,
forward, or take other actions with the information.
Organizations can create custom usage rights
templates such as "Confidential – Read-Only" that can
be applied directly to information such as financial
reports, product specifications, customer data, and e-
mail messages.

7. Application Server
• Application Server provides a complete solution
for hosting and managing high-performance
distributed business applications. Integrated
services, such as the .NET Framework, Web
Server Support, Message Queuing, COM+,
Windows Communication Foundation, and
Failover Clustering support improve productivity
throughout the application life cycle, from design
and development through deployment and
operations.

8. Dynamic Host Configuration Protocol Server
• The Dynamic Host Configuration Protocol (DHCP)
allows servers to assign, or lease, IP addresses to
computers and other devices that are enabled as
DHCP clients. Deploying DHCP servers on the
network automatically provides computers and
other TCP/IP based network devices with valid IP
addresses and the additional configuration
parameters these devices need./these are known
as DHCP options, which allow them to connect to
other network resources, such as DNS servers,
WINS servers, and routers.

9. DNS Server
• Domain Name System (DNS) provides a
standard method for associating names with
numeric Internet addresses. This lets users
refer to network computers by using easy-to-
remember names instead of a long series of
numbers. Windows DNS services can be
integrated with DHCP services, eliminating the
need to add DNS records as computers are
added to the network.

10. Fax Server
• Fax Server sends and receives faxes, and lets
you manage fax resources such as jobs,
settings, reports, and fax devices on this
computer or on the network.

11. File Services
• File Services provides technologies for storage
management, file replication, distributed
namespace management, fast file searching,
and streamlined client access to files, such as
UNIX-based client computers.

12. Hyper-V™
• Hyper-V provides the services that you can
use to create and manage virtual computing
environments and their resources. Virtual
computers operate in an isolated operating
environment. This lets you to run multiple
operating systems at the same time. You can
use a virtualized computing environment to
improve the efficiency of your computing
resources by using more of your hardware
resources.

13. Network Policy and Access Services
• Network Policy and Access Services delivers many
different methods to give users local and remote
network connectivity, to connect network
segments, and to allow network administrators to
centrally manage network access and client
health policies. With Network Access Services,
you can deploy VPN servers, dial-up servers,
routers, and 802.11-protected wireless access.
You can also deploy RADIUS servers and proxies,
and use Connection Manager Administration Kit
to create remote access profiles to let client
computers to connect to the network.

14. Print and Document Services
• Print and Document Services enables you to
centralize print server and network printer
management tasks. With this role, you can
also receive scanned documents from network
scanners, and route the documents to a
shared network resource, a Windows
SharePoint Services site, or to e-mail
addresses.

15. Remote Desktop Services
• Remote Desktop Services provides
technologies that enable users to access
Windows-based programs that are installed
on a remote desktop server, or to access the
Windows desktop itself, from almost any
computing device. Users can connect to a
remote desktop server to run programs and to
use network resources on that server.

16. Web Server (IIS)
• The Web Server (IIS) role in Windows
Server 2008 R2 lets you share information
with users on the Internet, an intranet, or an
extranet. Windows Server 2008 R2 delivers
IIS 7.5, a unified Web platform that integrates
IIS, ASP.NET, and Windows Communication
Foundation.

17. Windows Deployment Services
• You can use Windows Deployment Services to
install and configure remotely Windows
operating systems on computers that have Pre-
boot Execution Environment (PXE) boot ROMs.
Administration overhead is decreased through
the implementation of the WdsMgmt Microsoft
Management Console (MMC) snap-in that
manages all aspects of Windows Deployment
Services. Windows Deployment Services also
provides end-users an experience consistent with
Windows Setup.

18. Windows Server Update Services
• Windows Server Update Services allows
network administrators to specify the
Microsoft updates that should be installed, to
create separate groups of computers for
different sets of updates, and to obtain
reports on the compliance levels of the
computers and on the updates that must be
installed.
