The ip address conflicts with other systems on the network. The solution is as follows:
Method 1: The IP address conflicts with other systems on the network, and the settings are automatically obtained by DHCP.
The error message described by you should be that the IP address set by the network card conflicts with another computer on the network or the IP address of another network device. The so-called conflict is that the same address is used, and the error message is 00. :20:ED:9E:55:B6 is the MAC address of another computer or network device.

If your computer is on a LAN and the IP address of the network card is automatically assigned by the server on the LAN, on the Windows 2000 operating system, you can click the "Start" button and select "Command Prompt" in the "Accessories". Enter "ipconfig /renew" in the command line state to let the system release the current IP address and regain a new address. In Windows 98, you can click the "Start" button, select "Run", type "winipcfg", and on the dialog box that appears, choose to release the current IP, and then get one again. If your IP address is set to a fixed IP address, if you set it yourself, you can set another one. If it is assigned by the administrator, you need to contact the administrator to report the IP address conflict and request to change the IP address. Address or find the computer that caused the conflict to fix.
If you are using the computer in a stand-alone situation, you need to check which of the devices you are using 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.
The IP address can only be unique in each network. If it is repeated, an IP conflict will occur and the network cannot be connected to the network. You can modify it manually, as follows:

In windowsXP or windows2000:
Click Start--Set--Network and Dial-up Connection, right-click "Local Area Connection" in the network and dial-up connection window that appears, select the "Properties" command in the shortcut menu that appears, and the "Local Area Connection" Properties dialog box appears. In 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 emergence of "Internet Protocol (TCP / IP) In the Properties dialog box, select the "Use the following IP address" radio button in the "General" tab, and then fill in the required IP address, subnet weight and default gateway in the text box below.

At this time, if you used to manually set the IP address, you will see that the data has been filled in these items, then you do not have to change so much, just modify the IP address box, after the last point The number is OK. However, if you used to obtain an IP address automatically, you need to consult with the network administrator. The scope of the consultation includes the IP address range, subnet mask, default gateway, and IP address of the DNS server.
Method 2: View Network Connections - Properties
View network connection - Properties - TCP / IP properties - use fixed IP Internet access, IP is best to fill in your original automatically assigned IP address, so as not to cause conflict with others.
Method three: set from the run
Step 1 If the operating system of the computer you are using is: windows 98
Click "Start" → "Run" in the lower left corner, type: winipcfg, click "OK", in the pop-up window, click "Release All", then click "Update All" to solve the problem.
If you are prompted to update, you will need to restart your computer.
Step 2 If the operating system of the computer you are using is: windows 2000 or windows XP
Step 3 Click “Start” → “Run” in the lower left corner, type: ipconfig /release, click “OK”, click “Start” → “Run”, type: ipconfig /renew, click “OK” to solve the problem. .
Method 4: This is a sign of the ARP virus.
What if the ip address conflicts with other systems on the network? The characteristic of ARP virus virus attack is that the poisoned machine will forge the MAC address of a certain computer. If the fake address is the address of the gateway server, it will affect the entire network, and the user often appears to be disconnected from the Internet.
Note: If you encounter "local connection is restricted or no connection", you can't access the Internet. Xiaobian has provided a solution for everyone.
