Following are tasks that can increase the security, reliability and manageability of your DHCP Server role. Many of these tasks involve configuring your DHCP in conjunction with another Windows Server® 2008 technology or feature, such as Active Directory (AD) or Network Access Protection (NAP), and others describe how you can design your DHCP infrastructure for greatest efficiency:

• Increase fault tolerance by splitting DHCP scopes
  
  
• Eliminate manual updates of DNS records by configuring dynamic update and secure dynamic update
  
  
• Allow remote administration of DHCP servers by configuring Windows Firewall ports
  
  
• Prevent rogue DHCP servers on your network by authorizing DHCP servers in AD DS
  
  
• Enforce network access policies for client health by configuring DHCP with Network Access Protection
  
  
• Automate management of devices that have static IP addresses by creating DHCP reservations
  
  
• Support multiple subnets with one DHCP server by configuring DHCP relay agents
  
  
• Avoid reconfiguring DHCP on a new server by migrating an existing DHCP infrastructure
  
  
• Balance the load on your DHCP servers by using the 80/20 rule for scopes
  
  
• Centralize management of two or more DHCP servers as a single system by clustering DHCP servers
