What happens when DHCP server fails?

If DHCP Server looses connectivity or shuts down, the clients will keep the DHCP information for a certain period of time. After the period of time is finished, all clients will lose the IP information assigned by the DHCP Server.

What are the two most common reasons for DHCP failure?

Quick fix. A DHCP error can be triggered by two things. The first reason can lie within the configuration on your computer or device that allows a DHCP server to assign it an IP. The second reason is the configuration of the DHCP server itself.

Why does DHCP keep failing?

DHCP may fail to configure the client properly, either because DHCP could not communicate with a server, or because, although configuration responses were received, they were incorrect. Problems can also occur later in the life of a DHCP lease if the client cannot renew its IP addresses.

What is the configuration of DHCP?
