Dynamic Host Configuration Protocol (DHCP) is a special server configured to pass out IP information and other IP information to network clients. If a workstation has obtained IP configuration information from the wrong DHCP server or another workstation was configured with the same IP address you may need to retry and contact the DHCP server to release and renew your lease to obtain new IP configuration parameters.Depending on the policies and administration of your network DHCP leases time can be short and force clients to renew DHCP IP configurations. Shorter DHCP lease times are used in environments that only have a limited number of addresses that must be conserved.
