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
