The first step in setting up a DHCP server on a Windows Server 2008 system is
to install the DHCP Server feature on any servers with which are required to provide
the service. Before performing even this initial task, it is highly
recommended that any systems designated to act as DHCP servers be are assigned a
static IP address. If the server is currently obtaining a dynamic IP address
from another DHCP server, begin the installation process by assigning the
select the check box next to ''DHCP Server'' before clicking the ''Next''
button, read the information provided and click ''Next'' again to proceed to
the ''Network Connection Binding'' screen. It is wihitn within this screen that the
DHCP server is associated with specific network adapters installed in the
system. Select the network adapters for which the DHCP service will be
additional information such as the name of the parent domain (for example
techotopia.com) and the IP addresses of both preferred and alternate DNS
servers. If the DHCP server is required to provide these details for IPv4 clients,
enter them into the ''Specify IPv4 DNS Server Settings'' page and click
''Next''.
The next page allows initial DHCP scopes to be configured. A DHCP scope
defines one or more ranges of IP addresses from which an IP address may
assigned to a client and the duration of of the IP address lease (6 days for
wired clients and 8 hours for wireless clients). This may either be configured
now, or at a later point in the configuration process. The topic of defining
With the initial DHCP IPv4 configuration steps completed, the wizard
subsequently moves on the to the IPv6 settings. This is where a little background
information is useful. Windows Server 2008 supports two modes of IPv6 DHCP
operation, known as ''stateless'' and ''stateful''. In ''stateful'' mode,
clients obtain both an IP address and other information (such as DNS
addresses) though through the DHCPv6 server. In ''stateless'' mode, the clients
receive only the non-IP address information from the DHCPv6 server. In this
case, the IP address must be provided using some other mechanism, either by
'''Multicast Scope''' - Used to assign IP address ranges for Class D
networks.Multicast scopes do not have subnet masks, reservation or other
TCP/IP options. Multicast scope address ranges require that a Time To Live
(TTL) value be specified (essentially the number of routers a packet can pass
Assuming that all addresses in the scope range are on the same subnet, the
wizard will provide the option to specify exclusions within the scope.
Exclusions are essentially a ranges of one or more IP addresses within the
defined scope which are not available for assignment to clients. Multiple
exclusion ranges may be defined within a single scope by using the ''Add''
The next screen provide provides the option to configure DHCP options (such as default
gateway, DNS and WINS servers) which will be provided to clients along with
the dynamic IP address. If the ''yes'' option is selected, the wizard will
