conflict
|
Problem that occurs when an address within the IP address pool is being
used by a host that does not have an associated binding in the DHCP server's
database. Addresses with conflicts are removed from the pool and logged in
a conflicts list until you clear the list.

|
DHCP client

Host that uses DHCP to obtain an IP address and configuration settings.
|
|
DHCP options

Windows Name Service (WINS) server

over TCP/IP (NetBT) to register NetBIOS names and to resolve NetBIOS names
to IP addresses.
