1. Module 10: Designing Operating System Deployment and Maintenance

2. Module Overview Determining Operating System Deployment Requirements Designing Windows Deployment Services Windows Deployment Services Images Designing Multicast Transmission of Images Designing a Software Update Process

3. Lesson 1: Determining Operating System Deployment Requirements Design Options for Deploying Operating Systems Security Considerations for Operating System Deployment Tools for Operating System Deployment

4. Design Options for Deploying Operating Systems OptionsDescription Bare metalInstall on computer without existing software Light touchLimited manual interaction Zero touchNo manual interaction

5. Security Considerations for Operating System Deployment Security considerations for operating system deployment planning: Secure user credentials, PIDS, company information, or other restricted data in answer files, log files or image files Secure the storage locations for images, user state, and backups Scan source and destination computers for viruses Do not transmit data over the Internet unless the connection is encrypted Secure the PXE network boot process to prevent unauthorized users from joining computers to the domain Windows Server 2008 domain controllers do not allow the NETSETUP_JOIN_UNSECURE option

6. Lesson 2: Designing Windows Deployment Services Enhanced Features in WDS Network Infrastructure Requirements Comparing Transport Server and Deployment Server Considerations for Upgrading from RIS to WDS

7. Enhanced Features in WDS Enhanced features in WDS from RIS are: Support for deployment of Windows Vista and Windows Server 2008 Higher performing PXE and TFTP servers New boot menu format Support for.wim format Windows PE as boot operating system Multicast support

8. Network Infrastructure Requirements RequirementDescription Active Directory Domain Services WDS server must be a member of a domain. DHCP Configures workstations with an IP during PXE boot DNS Required for WDS server NTFS volume Required for image storage Credentials Must be a local administrator on WDS server to install Must be a domain user to start WDS client

9. Comparing Transport Server and Deployment Server Deployment ServerTransport Server Server requirements Requires AD DS, Dynamic Host Configuration Protocol (DHCP), and Dynamic Name Services (DNS) in the environment Does not require other servers in the environment PXE Supports PXE boot with the default PXE provider Supports PXE boot using the default PXE provider, or if you have a custom PXE provider Image server Includes the Windows Deployment Services Image Server (WdsImgSrv) Does not include the Windows Deployment Services Image Server (WdsImgSrv) Transmission method Allows unicasting and multicasting Allows only multicasting Management tools You manage using the Windows Deployment Services MMC snap-in or WDSUTIL You manage with WDSUTIL only Client Use the Windows Deployment Services client, WDSMCAST, or custom multicast client application Use WDSMCAST or custom client application only

10. Considerations for Upgrading from RIS to WDS Windows Server 2003 RIS to Windows Server 2008 WDS upgrade process: Upgrade RIS to WDS on Windows Server 2003 Change WDS from legacy mode to native mode Upgrade to Windows Server 2008

11. Lesson 3: Windows Deployment Services Images Image Capture Utilities Considerations for Maintaining Boot and Install Images

12. Image Capture Utilities FunctionalityWDSCaptureImageX Captures a partial volume?NoYes Captures a non-Sysprep image?NoYes Specifies compression type? Yes: only LZX or XPRESS Yes: LZX, XPRESS, or no compression Uploads directly to WDS Server?YesNo Can the process be automated?Yes Has a GUI?YesNo Provides additional functionality beyond image capture? NoYes Specifies capture exclusion list?Yes Captures directly to network location without making a local image copy? NoYes

13. Considerations for Maintaining Boot and Install Images Boot images: Must be Windows PE in.wim format Must be marked as boot from RAMDISK Boot.wim must not be older than the operating system being deployed Must have all necessary drivers Install images: Windows Vista can only be rearmed three times You can mount and edit offline images by using ImageX Editing offline images is not suitable for application installs You must export the image from WDS to edit offline

14. Lesson 4: Designing Multicast Transmission of Images Types of Multicast Transmissions Considerations for Designing Multicast Transmissions

15. Types of Multicast Transmissions Scheduled-cast: Multicast begins when criteria are met Criteria are: number of clients joined or specific day and time Clients cannot join after multicast has started Auto-cast: Multicast begins when a single computer requests it Additional computers can join in

16. Considerations for Designing Multicast Transmissions Considerations for designing multicast transmissions are: All routers must support multicasting Boot.wim from Windows Vista does not support multicasting (use boot.wim from 2008 media) If multiple servers are using multicast, they must use unique multicast addresses Use MADCAP to avoid conflicting multicast addresses You must restart WDS for network configuration changes to take effect

17. Lesson 5: Designing a Software Update Process Guidelines for Planning WSUS Infrastructure

18. Guidelines for Planning a WSUS Infrastructure When planning the number and placement of servers: Connect one WSUS server to the Internet Chain WSUS servers Place servers close to client computers When planning the configuration of servers: Download updates in the languages required Use a local database or Microsoft Update Create a synchronization schedule for downloads
