FAQ
Why can’t I connect to my DHCP server?
Try turning off or removing any firewalls or security programmes to see if the problem still happens. If you think these programmes are the reason you can’t reach your DHCP server, try uninstalling and reinstalling them, but make sure they are up to date first.
What happens if a computer Cannot communicate with the DHCP server?
When you try to lease, release, or renew an IP Address, you see the message “Unable to Contact DHCP Server.” This error means that your network interface card (NIC) can’t talk to the DHCP server to get a new lease so it can get a new IP address.
What causes DHCP failure?
DHCP might not be able to set up the client correctly either because it couldn’t talk to a server or because the configuration responses it did get were wrong. Later on in the life of a DHCP lease, problems can happen if the client can’t renew its IP addresses.
