When the DHCP client is in the renewing state, it must release its address immediately in the rare event that the DHCP
server sends a negative acknowledgment. The DHCP server sends this message to inform a client that it has incorrect
configuration information, forcing it to release its current address and acquire new information.

If the DHCP client cannot successfully renew its lease, the client enters a rebinding state. The client then sends a request
message to all DHCP servers in its range, attempting to renew its lease. Any DHCP server that can extend the lease sends
an acknowledgement containing the extended lease and updated configuration information. If the lease expires or if a
DHCP server responds with a negative acknowledgement, the client must release its current configuration, and then return
to the initializing state.

If the DHCP client uses more than one network adapter to connect to multiple networks, this protocol is followed for each
adapter that the user wants to configure for TCP/IP. Multi-homed systems are selectively configured for any combination of
the system’s interfaces.

When a DHCP-enabled computer is restarted, it sends a message to the DHCP server with its current configuration
information. The DHCP server either confirms this configuration or sends a negative reply so that the client must begin the
initializing state again. System startup might, therefore, result in a new IP address for a client computer, but neither the user
nor the network administrator has to take any action in the configuration process.

Before loading TCP/IP with an address acquired from the DHCP server, DHCP clients check for an IP address conflict by
sending an Address Resolution Protocol (ARP) request containing the address. If a conflict is found, TCP/IP does not start,
and the user receives an error message. The conflicting address should be removed for the list of active leases or it should
be excluded until the conflict is identified and resolved.
