DHCP AND WINDOWS DEPLOYMENT SERVICES
DYNAMIC HOST CONFIGURATION
PROTOCOL
• MAC Address
• IP Addressing
• DHCP Client
• DHCP Server
• Scope
• Exclusion Range
• Reservations
HISTORY OF DHCP
THE ROLE OF DHCP
• Dynamically assigns TCP/IP addresses
• Dynamically assigns TCP/IP configuration information
• Simplifies network administration
ETHERNET ADDRESS AND IP ADDRESS
• Each machine has an Ethernet address and IP address
• Ethernet is a unique 48 bit address
• Also known as MAC (media access control) addresses
IP ADDRESSING RULES AND CONCEPTS
• Addresses you cannot assign
•
•
•
•
Default route address: 0.0.0.0
Loopback address: 127.0.0.1
Network number: 172.17.13.0
IP Broadcast address: 172.17.13.255
DYNAMIC HOST CONFIGURATION PROTOCOL
• Used for
manageability
and automation
of IP address
assignment on
networks.
• Ie.
ISP’s use
DHCP when
you establish
connection.

Description
Used by clients to request configuration parameters
from a DHCP server
Used by servers to offer IP addresses to requesting
clients
Used by clients to accept or renew IP address
assignment and to decline unaccepted servers
Used by clients to reject an offered IP address
Used by servers to acknowledge a client’s
acceptance of an offered IP address
Used by servers to reject a client’s acceptance of an
offered IP address
Used by clients to terminate an IP address lease
Used by clients to obtain additional TCP/IP addresses
THE INITIAL DHCP LEASE PROCESS
DHCP LEASE RENEWAL PROCESS
LEASES, CLIENT OPTIONS EXCLUSIONS
AND RESERVATIONS
•
•
•
•
A lease determines how long the client will maintain the same
IP address before it is issued a new lease of another IP
address
Client options are configured during the setup or after. They
can range from simply setting the default gateway, DNS and
WINS servers to Network Time Servers and NetBios Settings
Exclusions are IP Addresses within the scope that you do not
want assigned dynamically. For instance you may statically
assign your server’s IP address and do not want that assigned
to another machine. What would happen if it did assign it’s
own IP address?
•
A single exclusion can be created or a range of exclusions
Reservations ensure that the same MAC gets the same ip
address every time. Reservations are created within the
scope.

WHAT IS A DHCP SCOPE?
WHAT IS A DHCP SCOPE?
WHAT ARE DHCP CLIENT
RESERVATIONS?
Client reservations permanently reserve a specific address
for a specific client.
MANUALLY RENEWING/RELEASING
IPCONFIG /RELEASE
Releases IP Address configuration and
lease
IPCONFIG /RENEW
Request to renew same IP address or new
IP Address
WINDOWS DEPLOYMENT-2008 R2
• What is Windows Deployment Services
• Installation Planning
• Automated Installation
• Microsoft Deployment Toolkit (MDT)
WHAT IS WINDOWS DEPLOYMENT
SERVICES?
• Enables rapid deployment of Windows to computers via
a network based installation.
• Formerly known as Remote Installation Services
•
WHAT IS WINDOWS DEPLOYMENT
SERVICES?
• Requirements:
• Deployment server is either a member server or a domain
controller within a domain.
• Active DNS server on the network
• Active DHCP server on the network
• Server has a NTFS partition to store images on

SERVICES?
INSTALLATION PLANNING
• Do you upgrade or perform a clean installation?
• Upgrade options to consider:
•
Roles/Features installed on legacy system will be installed during
the upgrade
•
Clean installation does not install any roles or features during
installation
• How should the drives be partitioned?
• Review requirements, minimum system partition is 32GB
INSTALLATION PLANNING
Can/should you
perform an
automated
installation?
• What would you need?
Decide on naming
conventions for
server.
Determine network
configuration and
security
requirements.
Apply any
firmware or BIOS
updates to
hardware.
INSTALLATION PLANNING
Installation strategies:
• High Touch Installation(HTI)A hands-on, manual
deployment, where you installing the Windows
operating system on each client computer by using
the retail installation DVD, and you manually
configure each computer. This strategy can save
your organization time and money by helping you
automate portions the installation process.
INSTALLATION PLANNING
Installation strategies:
• Lite Touch Installation(LTI)This strategy requires limited
interaction during deployment. Interaction occurs at the
beginning of the installation, but the remainder of the
process is automated.
• Zero Touch Installation(ZTI)This strategy requires no
interaction during deployment. The process is fully
automated through Systems Center Configuration
Manager 2012 (http://technet.microsoft.com/enus/library/gg682129.aspx).
INSTALLATION PLANNING
10 steps in
deployment
process:
•Import source files to management computer
•Create task sequence and boot image for reference computer
•Update deployment share with source files, boot image and task sequence
•Transfer source files, boot image and task sequence from the deployment share to the reference
computer.
•Run deployment wizard on the reference computer and capture image.
•Send captured image back to the management computer.
•Create task sequence and boot image for target company, using image captured in #5 as
source.
•Update deployment share with boot image source files and task sequence
•Transfer source files, boot image, and task sequence from the deployment share to the target
computer
•Run deployment wizard on the target computer.
AUTOMATED INSTALLATION OPTIONS
Windows Deployment
Services (WDS)
application used to rapidly
deploy workstations by using
installation files or a
preconfigured image
(Windows Image *.WIM file).
Requirements for WDS:
• Servers and/or workstations can be deployed with little
administrative interaction.
• Active Directory
• Dynamic Host Configuration Protocol (DHCP)
• Pre-boot Execution (PXE) enabled network interface card (NIC)
• NTFS formatted non-system drive
• Functioning DNS
