The DHCP Client service on your computer did not receive a response from the DHCP server to renew your computer's IP address lease. The client still has a valid IP address and periodically will try to get an address lease extension.
This could be caused by network connectivity issues, a DHCP server or relay malfunction, firewall issues, or a malfunction of your computer's network interface card or driver.
User Action
If your computer is connected to the network by cable, confirm that the cable is plugged in. If you have a wireless network connection, confirm that you have a signal and the proper credentials for the wireless network.
The DHCP Client service will continue trying to get an IP address lease extension until it succeeds, so DHCP might establish communications on its own.
If communication between the DHCP client and the DHCP server is not established automatically, check the following possible causes and take corrective action:
- The DHCP server is down or not responding.
- The DHCP relay is not functioning correctly.
- The network is down.
- The firewall on your computer is blocking out network broadcast traffic.
- Your computer's network interface card or driver is not functioning correctly.
