WinXP IP address conflicts with other systems on the network how to solve

Causes of conflict

1, IP address is equivalent to every computer ID card number, just like your identity card, everyone's number is different, there can be no other people's identity card number is the same as you, in the LAN environment, For example, your computer's IP settings are 192.168.2.10 and the IP of another computer is set to 192.168.2.10, which can cause IP to conflict with other systems.

2, virus problem: Lan ARP virus attack caused. ARP, the Address Resolution Protocol, realizes its physical address through an IP address. The ARP protocol is a protocol to the TCP/IP protocol group for translating network addresses into physical addresses (also known as MAC addresses). ARP virus is not the name of a virus, but the use of ARP protocol to spread the vulnerabilities of a class of viruses. Currently on the Internet, ARP attacks usually have two kinds of means: Gateway spoofing and routing spoofing. is an intrusion of the local area network computer virus Trojan. The threat to private information about computer users is great.

3, if your computer is in the LAN environment, it may be that there are other people's computer IP settings and your computer IP set to the same.

Solving method

1, set up to be automatically obtained by DHCP

The error message described is that the IP address set by the network adapter is in conflict with the IP address of another computer on the net or other network device, and the so-called conflict is the same address, such as the 00:20:ed:9e:55 in the error hint: B6 is the MAC address of the other computer or network device.

If your computer is in a local area network, and the network card IP address is automatically assigned through the LAN server, you can click the "Start" button, select "Command Prompt" in "attachment", enter "Ipconfig/renew" in the command line state, and let the system release the current IP address. Re-obtain a new address. If your IP address is set to a fixed IP address, if you set it yourself, you can set another, if it is assigned by the administrator, then you need to contact the administrator, report the problem of IP address conflict, request to replace the IP address or to find a conflict computer to amend.

If you use a computer on a stand-alone condition, you need to check which device in your device is the cause of the conflict, such as whether the IP address of the ADSL modem is the same as the IP address of your network card.

2, modify the local IP address

Click Start-Set-"Network and dial-up connections, right-click Local Area Connection in the network and dial-up connections that appear, select Properties on the shortcut menu that appears, and the Local Area Connection Properties dialog box appears."

On the General tab, in the middle of the "this connection makes the following components" list box, select Internet Protocol (TCP/IP) Click the Properties button in the Internet Protocol (TCP/IP) Properties dialog box that appears, select the General tab of the Use the following IP Address radio button, and then you can fill in the required IP address, subnet Zengcuoan code, and default gateway in the text box below.

If you have previously used the automatic IP address, then you need to consult the network provider, the content of the consultation includes, IP address range, subnet mask, default gateway, DNS server IP address.

3, if the ARP virus attack, then first upgrade your security software, and then completely killing your computer. And the firewall level to the maximum.
