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
Reasons for Planning the Operating System Deployment
Reasons for operating system deployment planning:
• Ensuring continued productivity during workstation rollouts
• Ensuring critical network services continue to be available during server upgrades or installations
• Alleviating application compatibility issues
• Ensuring new features are evaluated properly and all impacts to the current environment are considered
• Ensuring all deployment processes and scripts are properly tested
Determining Storage Requirements
Storage requirements include:
Deployment images
User state migration data
Computer backups
Application and operating system source files
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
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
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
Considerations for Designing WDS
Considerations for designing WDS are:
• IPv6 is not supported for this version of Windows Deployment Services
• Use only the boot.wim file from the Windows Server 2008 DVD
• WDS and DHCP both attempts to listen UDP on port 67 If DHCP is installed on a server that is located on a different subnet you will need to do one of the following:
• Configure DHCP relay to the DHCP server and WDS PXE server
• Add DHCP options 66 and 67
