The Goal For This Session
• To help you decide which tool is right for you
• All tools deploy both Server and Desktop Operating
Systems (OSs)
• Both tools are either FREE or In-The-Box
But First …
Windows Deployment Service
• WDS replaces Remote Installation Services (RIS)
• Provides both boot and installation images from the
WDS server
• Supports .WIM and .VHD technology
WDS Requirements
DHCP

AD/DNS

Bare-Metal
WDS
Install WDS
• Install WDS on a 2008 (or R2) server
• Server Manager
• Add Roles
• Select Windows Deployment Services from the list of
roles
Configuring WDS
WDS snap-in
Right-click Servers
Add Server –
defaults to local
server
Right-click your
server and choose
Configure Server.
Store your images on a drive other than where the OS resides

Adding a Boot Image
• A boot image is a Windows Pre Installation
Environment (WinPE)
• The most current will always be best
• Windows 7 SP1 Boot.wim can deploy
• Vista SP1 – Windows 7 – Windows 7 SP1
• Windows Server 2003 R2, 2008 and 2008 R2
• Use an older WinPE will produce undesired results

Compare WinPEs
Adding an OS Image
• Both .wim and .vhd are supported
• Adding a .wim
• Right–click Install Images
• Add Install Image
• Image Groups
• Adding a .vhd
• Elevated command prompt
• WDSUTIL /Add-Image /ImageFile:\\Server\Share \Win7.vhd
/Server:WDSServer /ImageType:Install
/ImageGroup:Windows7 /Filename:"Windows7.vhd"
Add Drivers & Applications
• 3rd party drivers only
• No Applications can be deployed from WDS
• Only a Thick image containing your applications
From The Client
• Perform a Network Boot
• Sometimes called a Pre Execution Boot Process
• OR
• PXE Boot

WDS Client Deployment
WDSServer sends packet 1 to client1
WDSServer sends packet 1 to client2
WDSServer sends packet 1 to client3
WDSServer sends packet 1 to all clients
WDSServer sends packet 1 to client1, client2, client3
Multiple streams of traffic
Optimized rates based on
client connection
Fast
Client Auto Removal
Medium
Slower clients can be dropped
to unicast or entirely (only in
standard multicast)
Boot Image Multicast
Slow
Windows PE boot
images can use multicast
(clients with EFI)
WDS Server
First client joins “transmission”

Create A Reference
Add Components
• Applications
• Office 2010
• Adobe Reader
• Drivers
• 3rd party
• Packages
• OS patches
• Language packs
Over Time You Will Have Multiple Images To
Deploy:
• Multiple OSs
• Windows 7 SP1 base DVD
• Windows 7 custom Hybrid .wim image
• Windows Server 2008 R2
• Drivers for different models of machines
• Applications for different groups of users
• So you will need a way to group components together
for a specific deployment
• This is called a Task Sequence
Update The Deployment Share
• Updating the deployment share creates a custom
MDT Windows Pre Installation Environment (WinPE)
• This WinPE is very intelligent
• Pre-configured to know who the MDT server is and the
name of the Deployment Share

Quick Note on Using USB Hard Drives
• Different BIOS number the USB hard drives
differently
• When numbered 0 – they can show up as fixed drives
and you don’t want that
• ConfigMgr OSD does not support booting from USB hard
drives

Automate the Clients Experience
• When you run the Deployment Wizard
• Choose which screens are displayed during the
deployment
• Suppress the ones you don’t want anyone to see or
change like:
• Product Key
• Administrator’s password
• Customize the words displayed on the pages

Linked Deployment Shares (LDS)
• LDS allows you to copy a subset (or all if you choose)
of components to another machine
• Even Windows 7 can host a LDS
• But, if you host the LDS on a server you can
integrate WDS with it

MDT Database
• Automate what gets installed on a computer
• Original image and re-imaging
• How it works:
• When a client begins the Deployment Wizard a script runs:
ZTIGather.wsf
• Gathers all kinds of information from the client like:
•
•
•
•
Universally Unique ID (UUID)
Serial number
Asset tag
MACAddress
• Queries the MDT database for a match
• Applies the configured settings
MDT 2012 & ConfigManager
• Aligned more closely with Config Manager 2012
• Shipping times:
• RTM after Config Manager 2012 ships
• Still need to integrate MDT 2012 into Config Manager 2012
• New Terminology
• Advertise = Deploy
• Packages can either be optional or mandatory
• Optional = available
• Mandatory = required
New Features
• New Deployment Wizard
• Deploy .vhd images
• Supports deploying ThinPC and POSReady
• ThinPC – basic Win7
• Citrix or Terminal Services client
• POSReady
• Point of Sales – cash registers
• Cross platform deployment
• 32 bit WinPE can deploy 32 or 64 bit OSs
More New Features
• Diagnosis and Recovery Toolset (DART)
• Allows remote control of target machines
• Even in the WinPE phase
• Deployment Workbench gets a new tab
• Monitor deployment clients
• Properties of the deployment share are more streamlined
• New UDI wizard designer
• Image factory – create .wim or .vhd
• Vhd can be deployed via Virtual Machine Manager as
templates to create new virtual machines
Unified Extensible Firmware Interface (UEFI)
• Full support of UEFI
• Intels replacement for PC BIOS
• Offers support for GUID partition tables (GPT)
• MBR partition tables restricted disk partition sizes to a maximum of
2.19 TB
• MBR supports only 4 partitions
•
•
4 primary
3 primary and 1 extended (break it up into logicals)
•
•
1 zettabyte = 1 billion terabytes
Supports upto 128 volumes
• GPT allows a maximum disk and partition size of 9.4 ZB
512 Byte – 4K Misalignment
• Legacy drives support 512-byte physical sectors
• OSs use 4K logical block sizes
• virtual memory pages & file systems like NTFS

Sector Overhead
• Data
• ID Information
• identify each sector by number and location
• a single bit is used to indicate if the sector has been marked defective
• Synchronization Fields
• Where do I go to find the next piece of a file
• Error Correcting Code (ECC)
• ensure data integrity
• Gaps or spacers
• separate sector areas and gives the controller time to process what has been
read before moving on to process more data

What’s The Problem? The Fix
• The result is performance is degraded
• 10% – 30%
• The fix is for hardware and OSs to both read at a 4K
sector size
• 4K sector sizes are not supported for XP
• But they are in WinPE 3.0
