产品: Windows Operating System

版本: 5.2
符号名称: EVENT_FAILED_TO_RENEW
消息: Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address %1. The following error occurred:
%2. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
解释
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.
用户操作
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.
不管你是无线网还是有线网，确保你的网络连接正常。
你的电脑会一直尝试获取ip直到成功，DHCP客户端和服务器一般会自行建立通信。
出问题的原因可能有：
DHCP服务器关闭或者没有响应。
DHCP中转不正常
网络被关闭
你的防火墙阻止了网络广播信号的传送
你的网卡或驱动不正常
英文很烂，将就着看吧。
