DHCP in Windows Server 2003 prevents unauthorized DHCP servers from creating address assignment conflicts. This feature solves problems that could otherwise occur if users accidentally created unauthorized DHCP servers that could unintentionally assign IP addresses to clients elsewhere on the network. For example, a user could create a local DHCP server by using nonunique Net 10 addresses from the private address space, unintentionally leasing the addresses to clients requesting addresses.
DHCP in Windows Server 2003 includes management features that both prevent unauthorized deployments and detect existing unauthorized DHCP servers by requiring authentication by an authorized administrator to make a DHCP server active on the network.
