Common Networking Functions
WS08 includes features and functionalities that support
almost every conceivable networking service. But not all of these
functionalities are new or updated in Windows Server 2008. It is, therefore,
important to first establish a common vocabulary on standard networking services
and then identify where WS08 brings new features and functionalities to help
draw a graphical map of the new WS08 features. This will provide you with a
simple graphical layout of the new Windows Server 2008 feature set.
Small organizations or networks that include only a single
site will often include a basic set of networking services. These services tend
to focus on the following:
Domain Services Using
Active Directory to centrally store and manage all user accounts makes sense in
organizations of all sizes. The alternativeusing workgroup practicesmeans
having to manage multiple security account databases, one on each server or
workstation, in fact. Active Directory is so simple to use that it simply does
not make sense to use anything else.
NOTE Active Directory Domain Services (ADDS) relies on the
Domain Name System (DNS) to operate. Therefore, any installation of ADDS will
require at least one server running the DNS service. Note that in small-scale
ADDS installations, you are automatically prompted to perform a simple DNS
and Printer Sharing Storing documents centrally has always made sense because you only
have to protect one single location. Every organization has a use for
central file and printer management, even if new collaboration features
offer a better way to manage documents and have teams interact.
- Collaboration Services With Windows SharePoint Services (WSS), organizations
can have teams interact with each other through a Web-based team
structure. Since almost all organizational activity takes the form of a
project, using team sites and collaboration services only makes sense,
especially since WSS is so easy to install and manage.
- Database Services Windows SharePoint Services relies on a
databasein this case, the Windows Internal Database, which is, in fact, a
version of SQL Server Embedded edition.
- E-mail Services Most
organizations also rely on e-mail services. Though Windows Server 2008
does provide the simple message transfer protocol (SMTP) service,
organizations usually opt for a professional e-mail service, such as that
provided by Microsoft Exchange Server.
- Backup and Restore Services All
organizations will want to partake of Windows Backup to protect their
systems, both at the data and the operating system level. The new Backup
tool in Windows Server 2008 provides protection for both.
These often form the basic services that most
organizations require. Optionally, even small organizations will also rely on
the following services:
Services Any organization that has a connection to the
external world through the Internet will want to make sure they are
completely protected. The only way to do so is to implement an advanced
Services Windows Server 2008 can provide integrated fax
services, freeing organizations from needing a conventional fax machine.
Services Terminal Services (TS) provides the ability to
run applications on a server instead of on the users workstation. The
advantage of this is that organizations need to manage applications only
in one central location. In addition, with Windows Server 2008, the use of
TS applications is completely transparent to end users, since it appears
as if they are working off the local machine.
CAUTION Terminal Service applications are not appropriate for
mobile or disconnected users because they do not offer any kind of offline
caching. Therefore, when a user is disconnected, they do not have access to TS
- Hyper-V This
is a core service of the new datacenter. It supports the virtualization of
all other service offerings. This service is installed on all hardware,
and all other services are installed within virtual machines.
Access Services (NAS) With the proliferation of home
offices, more and more organizations are relying on network access
services, such as virtual private networks (VPNs), to let home workers
access the corporate network over common home-based Internet connections.
Services With the advent of new Windows Deployment
Services in Windows Server 2008, many organizations will want to take
advantage of this feature to automate the installation and deployment of
Windows XP and Windows Vista machines. Larger organizations will
definitely want to use these services to deploy servers as well as
Server Update Services With the proliferation of attacks
on systems of all types, organizations of all sizes will want to make sure
they implement a system for keeping all of their computersworkstations
and serversup to date at all times. Windows Server Update Services (WSUS)
is not part of WS08, but is free and can be obtained at
Registration is required to obtain the download.
In addition, any organization that includes more than one
site will need to ensure that the services they provide at one site are
available at any other. This is done through a series of different features,
which rely mostly on either a duplication of the base services in remote sites
or the use of a replication mechanism to copy data from one location to the
other. The implementation of these systems is more complex than single-site
Larger organizations will add more services to their
network just because of the nature of their organization. These will include:
Services Anyone who wants to control identity and ensure
that users are who they claim they are at all times will want to take
advantage of Active Directory Certificate Services, a public key
infrastructure system that provides electronic certificates to users and
machines in order to clearly identify who they are.
NOTE For more information on public key infrastructures
(PKI), see the Advanced Public Key Infrastructures section at
Management Services Organizations concerned about the
protection of their intellectual data will want to implement Active
Directory Rights Management Services (ADRMS). ADRMS can protect electronic
documents from tampering through the inclusion of protection mechanisms
directly within the documents.
Storage Organizations maintaining large deposits of
information will want to take advantage of advanced storage systems, such
as storage area networks (SANs). Windows Server 2008 provides new ways to
access and manage SANs.
Services and Load Balancing Organizations running N-tier
applicationsapplications that are distributed among different server
roleswill want to protect their availability through the use of the
Windows Clustering Service (WCS)a service that provides availability
through a failover capacity to another server running the same
serviceand/or Network Load Balancing (NLB)a service that provides
availability through the use of multiple servers running identical
Services Organizations relying on large data structures
will want to run more than the Windows Internal Database and will rely on
other versions of SQL Server to protect their databases.
Applications Organizations providing custom services,
both internally and externally, will need to rely on Internet Information
Services (IIS) to deliver a consistent Web experience to end users.
Services Organizations running N-tier applications will
want to support them with middleware, such as the Microsoft .NET Framework,
COM+, and other third-party components. These run on middleware servers.
Management Services Organizations that take advantage of
Microsoft Software Assurance and Volume Licensing will want to implement
this new WS08 role. Key Management Services (KMS) controls the activation
of Microsoft volume-licensed software from both clients and servers from
within your firewall.
