  1. IT:Network:Microsoft Server 2 DHCP and Windows Deployment Services

  2. Dynamic Host Configuration Protocol • MAC Address • IP Addressing • DHCP Client • DHCP Server • Scope • Exclusion Range • Reservations

  3. HISTORY OF DHCP

  4. THE ROLE OF DHCP • Dynamically assigns TCP/IP addresses • Dynamically assigns TCP/IP configuration information • Simplifies network administration

  5. Ethernet Address and IP address • Each machine has an Ethernet address and IP address • Ethernet is a unique 48 bit address • Also known as MAC (media access control) addresses

  6. IP Addressing Rules and Concepts • Addresses you cannot assign • Default route address: 0.0.0.0 • Loopback address: 127.0.0.1 • Network number: 172.17.13.0 • IP Broadcast address: 172.17.13.255

  7. Dynamic Host Configuration Protocol • Used for manageability and automation of IP address assignment on networks. • Ie. ISP’s use DHCP when you establish connection.

  9. THE INITIAL DHCP LEASE PROCESS

  10. DHCP LEASE RENEWAL PROCESS

  11. 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’s IP address and do not want that assigned to another machine. What would happen if it did assign it’s own IP address? • A single exclusion can be created or a range of exclusions • Reservations ensure that the same MAC gets the same ip address every time. Reservations are created within the scope.

  13. WHAT IS A DHCP SCOPE?

  14. WHAT IS A DHCP SCOPE?

  15. WHAT ARE DHCP CLIENT RESERVATIONS? Client reservations permanently reserve a specific address for a specific client.

  16. Manually Renewing/Releasing

  17. Windows Deployment-2008 R2 • What is Windows Deployment Services • Installation Planning • Automated Installation • Microsoft Deployment Toolkit (MDT)

  18. What is Windows Deployment Services? • Enables rapid deployment of Windows to computers via a network based installation. • Formerly known as Remote Installation Services

  19. What is Windows Deployment Services? • Requirements: • Deployment server is either a member server or a domain controller within a domain. • Active DNS server on the network • Active DHCP server on the network • Server has a NTFS partition to store images on

  20. What is Windows Deployment Services?

  21. What is Windows Deployment Services?

  22. Installation Planning • Do you upgrade or perform a clean installation? • Upgrade options to consider: • Roles/Features installed on legacy system will be installed during the upgrade • Clean installation does not install any roles or features during installation • How should the drives be partitioned? • Review requirements, minimum system partition is 32GB
