In Windows Server 2008, Microsoft addresses this issue by introducing an installation
option called Server Core. This installation option installs the most basic Windows
Server component for the role the Windows Server will perform. There is one caveat,
however, in that currently, Microsoft supports the Server Core installation for only a
handful of predefined roles, such as domain controller (DC), DNS Server, Dynamic Host
Configuration Protocol (DHCP) Server, and file server. This basic installation of Windows
Server 2008 doesn??™t even install Windows Explorer, so you have no desktop with which
to interact. Instead, the system must be managed completely through the command line
or via Terminal Services. Microsoft realized that if a server is performing a very distinct
infrastructure role, excess services need not be installed on it??”not even a full graphical
user interface (GUI). This minimizes the server??™s attack surface and will hopefully help
reduce downtime by reducing the need to install system updates on the server.
ROLES SUPPORTED BY SERVER CORE
Microsoft intended the Server Core installation method to be used for infrastructurerelated
services. Because of all this, Microsoft supports only the following seven roles in
the Server Core installations:
?–? Active Directory Domain Services (AD DS)
?– Active Directory Lightweight Directory Services (AD LDS)
?– File Server
?– DHCP Server
?– DNS Server
?– Print Server
?–? Streaming Media Services
These roles are not mutually exclusive.
