Ethernet Address and IP address
Each machine has an
Ethernet address and IP
address
Ethernetis a unique 48
bit address
Alsoknown as MAC
(media access control)
addresses
Routable(public)and Non
Routable(private) Addresses
RFC 1918 defines three non-routable ranges of IP
address
10.0.0.0-10.255.255.255
172.16.0.0-172.31.255.255
192.168.0.0-192.168.255.255
Ports and Sockets
All computer communication basically involves two programs
talking to each other.
◦ Internet Explorer communicating with and Apache Web server
◦ Running and FTP Client to access files on an FTP Server
◦ Using Microsoft Outlook to send an email message to an
Exchange SMTP server
This communication is like a phone conversation. You must
have the number and the person must be there to answer
In the TCP world, the phone number is known as a socket.
Which is comprised of three parts:
◦ IP Address
◦ Receiving programs port number
◦ And whether or not that port number is TCP or UDP.
Ports and Sockets
The web browser
establishes a connection
to a web/ftp server.
That web server returns
communication on an
undetermined port.
Dynamic Host Configuration Protocol
Used for manageability
and automation of IP
address assignment on
networks.
Ie.ISP’s use DHCP when
you establish connection.
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 and do not want that assigned to another
machine. Why?
Reservations ensure that the same MAC gets the same ip
address every time.
Windows Distributions Services
(formerly Remote Installation Services)
Server
Client
DHCP
RIPREP
SYSPREP
GHOST
WDS
Installs OS onto client station
◦ Can be a workstation client
◦ Can be a server client
Three options
◦ Simple install
Solves how to get to the network place first
From NIC
◦ Scripted install
Same as before however you can automate with an answer file
◦ Complete System image with minimal setup interaction
Only used with Workstation version
Similar to GHOST in that it takes an image of the workstation
WDS Requirements
Active Directory. A Windows Deployment Services server must be
either a member of an Active Directory domain or a domain
controller for an Active Directory domain. The Active Directory
domain and forest versions are irrelevant; all domain and forest
configurations support Windows Deployment Services.
DHCP. You must have a working DHCP server with an active scope
on the network because Windows Deployment Services uses PXE,
which in turn, uses DHCP.
DNS. A DNS server on the network is required to run Windows
Deployment Services.
An NTFS partition. The server running Windows Deployment
Services requires an NTFS partition for the image store.•Windows
Server 2003 SP1 with RIS installed. RIS does not have to be
configured, but must be installed.
WDS w/ Ghost
WDS can deploy ghost images
Ghost images are a snapshot/clone of a pre-
existing/configured workstation
www.symantec.com
WDS v. Ghost
Ghost is hardware specific. You can select options
for plug and play, however, it must be on a like
machine
WDS is a REMOTE INSTALL of the Operating
system. It does a complete install “across the wire”
as if you were in front of the machine installing via
the media.
WDS Advanced Applications
SYSPREP
Strips all Security Identifiers from the target client.
Computer Name, SID, GUID etc.
If not done, you will experience problems on network.
Runs a “mini-setup” during first boot that can be used to
uniquely identify station. This can be automated
RIPREP
Similarto GHOST in the fact that it “images/clones” a
preconfigured workstation.
WDS Advanced Applications
Setup Manager
Used to create an answer files for automated or
unattended installations.
Windows System Image Manager
(Windows SIM)
Windows System Image Manager (Windows SIM) creates
and manages unattended Windows Setup answer files in a
graphical user interface (GUI).
Answer files are XML files that are used during
Windows Setup to configure and customize the default
Windows installation.
For example, you can use Windows SIM to create an answer file
that partitions and formats a disk before installing Windows.
Windows SIM also changes the default setting for the Internet
Explorer home page, and configures Windows to boot to audit
mode after installation. By modifying settings in the answer file,
Windows SIM can also install third-party applications, device
drivers, language packs, and other updates.
