- 1. DHCP
- 4. This topic describes the Dynamic Host Configuration Protocol (DHCP) functionality that is new or changed in Windows Server 2012 R2 and Windows Server 2012. • DHCP is an Internet Engineering Task Force (IETF) standard that is designed to reduce the administrative burden and complexity of configuring hosts on a TCP/IP-based network, such as a private intranet. By using the DHCP Server service, the process of configuring TCP/IP on DHCP clients is automatic. •
- 5. What’s new in DHCP in Windows Server 2012 R2 You can use DHCP policies to configure conditions based on the fully qualified domain name (FQDN) of DHCP clients, and to register workgroup computers using a guest DNS suffix. You can enable DNS registration of address (A) and pointer (PTR) records, or just enable registration of A records.
- 6. Windows PowerShell for DHCP server New Windows PowerShell cmdlets are available in Windows Server 2012 R2. You can use these cmdlets to perform tasks such as creating DHCP security groups, setting DNS credentials, managing superscopes, and managing multicast scopes. Improvements have also been made in existing Windows PowerShell cmdlets for DHCP server to help perform tasks such as changing the mode of a failover relationship and configuring DNS settings for a DHCP policy.
- 7. In Windows Server 2012, DHCP offers enhanced support in the following areas: 1-DHCP failover. 2-Policy-based assignment. 3-Windows PowerShell for DHCP Server.
- 8. DHCP failover This feature provides the ability to have two DHCP servers serve IP addresses and option configuration to the same subnet or scope, providing for continuous availability of DHCP service to clients. The two DHCP servers replicate lease information between them, allowing one server to assume responsibility for servicing of clients for the entire subnet when the other server is unavailable. It is also possible to configure failover in a load-balancing configuration with client requests distributed between the two servers in a failover relationship. For more information about DHCP failover, see Step-by-Step: Configure DHCP for Failover.
- 9. Policy-based assignment With policy based assignment, the DHCP the server evaluates DHCP requests against policies that you define. Policies are applicable for a specific scope with a defined processing order. Policies applicable at a scope can be configured at the scope or inherited from server wide policies. A single client request can match multiple policies, and policies can be associated with multiple address ranges. For more information about DHCP policy based assignment, see Step-by-Step: Configure DHCP Using Policy-based Assignment.
- 10. Windows PowerShell for DHCP Server Windows Server 2012 provides task-oriented Windows PowerShell cmdlets for DHCP server management. The DHCP server configuration operations are implemented in Windows Server 2012 as Common Information Model (CIM) based cmdlets. Windows PowerShell uses object pipelining to eliminate the need for parsing and manipulation of text output. Windows PowerShell for DHCP Server includes 103 cmdlets, covering multiple aspects of DHCP server configuration and management.
- 11. Reliable DHCP service is crucial to clients’ normal network connectivity. The requirements for this service evolved over the years. While the Split-Scope configuration has been a de facto standard for a long time, it’s been accompanied by two major short-comings. - Lack of IP addresses continuity in case of DHCP server failure. - Totally unsuitable for highly utilized scopes. Another High Availability (HA) solution has been the DHCP cluster deployment. Naturally, this HA option has been available strictly to enterprises with the corresponding budget and expertise. Besides of its complex configuration and maintenance DHCP cluster solution comes with a single point of failure – the shared storage.
