Image deployment flow with WDS (And it’s exactly what we are showing today)1. Prepare a Windows 7 image for distribution

2. Configure WDS1. DHCP settings, PXE settings

2. Boot image creation

3. Capture and upload the Windows 7 image to WDS

4. Boot a bare metal client to receive the Windows 7 image

5. Boot a bare metal client to receive the Windows 7 image - unattend

Why Use WDS?

Performs network-based installations

Deploys Windows images to bare metal computers

Supports mixed Windows environments

Reduces deployment cost - FREE

Utilizes standard Windows technologiesWindows PE

.wim files

.vhd files

Windows Pre Installation Environmentaka…WinPE

Scaled down version of the Windows 7 Kernel

Boots into and runs from RAMX: drive (default driver letter)

Reboots every 72 hours

Command Line Interface Only

Can be converted to a bootable .ISO and placed on:CD, DVD, USB Flash Drive, external HD

You can create your own or use the boot.wim from W7 or Server 2008 R2 DVD (\Sources folder)

.Wim Side Trip

One of Microsoft’s image format

On WDS .wims are stored in image groups

Multiple images stored in a single image groupSingle instancing

No redundant file storage

Service image offlineApply patches quick and easily

VHD Image Formats - NEW

You can create a .vhd, apply a .wim to it and tell bcdedit to boot that OS

Mounting a VHD is called “attaching"

Un-Mounting a .VHD is called “detaching”

Diskpart & Imagex are the basic tools of choice to work with .vhd

.vhd images can contain more than one partition

Back To WDS:Requirements

WDS server must be a member of an Active Directory domain

DHCP

DNS

NTFS partition on which to store images

WDS on Server 2003

Installing WDS on a 2003 SP1 Server Install RIS

Install patch from the WAIK: windows_deployment_services_update.exe

Installing WDS on a 2003 SP2 ServerControl Panel / Add/Remove Programs / Windows Components / WDS

WDS on Server 2008 (& 2008 R2)

Configuring WDS – Welcome

WDS snap-in

Expand WDS

Right-click your server “Configure Server”

Store Your Images

Adding The Images

Within the WDS snap-in

Add Boot imagesThese are WinPEs

Add .Wim Install imagesImage groups and single instancing

Capture an ImageModel machine configured exactly the way you want it:

Install an OS

Add and configure Applications

Desktop settings

SYSPREP-reseal switch

-generalize

PXE Boot to a Capture Image

Creating An Image Using WDSCreate a Capture Image

WDS snap-in -> open Boot Images

R-click one W7 or 2008 R2 boot.wim from DVD /Sources

Choose to Create Capture Image…Give it a name, description and path to store it

When the wizard completes add the newly created Capture Boot Image to your list of Boot Images

Adding a .VHD

Cannot be added in the UI

Use WDSUtil cli

Need a vhd image group

Can’t mix vhds and wims

No single instancing occurrs

WDSUtil /verbose /progress /add-image /imagefile:<Path> /imagetype:install / imagegroup:VHD

2. WDS and DHCP on different subnets Client find WDS through options 66 and 67 set in DHCP

3. WDS & DHCP on same server Client must find WDS through Option 60 in DHCP

Message From Administrator

How do you set a message from the administrator?

On the WDS server from a command prompt type:

WDSUtil /set-server /AutoAddPolicy/message:"To contact your network administrator please dial 123-4567“

Pending Devices

Can’t use PXE

Create a Discover Image

WDS snap-in -> expand Boot Images

R-click a boot image W7 or 2008 R2 boot.wim from DVD /Sources

Choose to Create Discover Image…Give it a name, description, path to store it and name of WDS server to connect to

Using the WAIK tools create a bootable .ISO that contains the new discover .wim

Burn to CD/DVD, USB, external HD

Boot the WDS Client to receive the image

2 ways to create a multicast transmission from within the WDS snap-in

Right-click Multicast Transmissions and choose Create Multicast Transmission

ORDrill down to your Install Image and right-click the image then choose Create Multicast Transmission

Modifying an Image.vhd can be serviced offline

RemoteInstall folderImages

Find your .vhd

Use Diskpart to attach the vhd

Use DISM to add packages, drivers, enable/disable windows components

.wim can be patched using WSIM scriptsAdd your packages to the Install script

OR

Disable image / export image /service offline with DISM

For use in computer-refresh only

Enables local file migration without copying or moving files

Scans the computer for user files and settings then creates a directory of links to those files using hard-links

Hard-links are then remapped into the appropriate locations in new operating system

Processes migration jobs in less time using megabytes of disk space instead of gigabytes
