Windows has detected an IP address conflict


Another computer on this network has the same IP address as this computer. Contact your network administrator for help resolving this issue. More details are available in the windows system event log.




Note I have got this message three times in the past month!! I have no idea what is going on or why I'm getting this message.


Both my windows 10 laptop and windows 7 computer have got this message.


What normally does this message mean and what can cause it.

Method 1:

Restart Your Router

Your router can be failing to assign appropriate IP address to the connected device. This can be caused by a temporary glitch, but most of the time this is cleared by a simple reboot/power cycle. To do this, switch off the router, wait 1-2 minutes and turn it back on. Once it’s on, give it another 2-3 minutes to settle and then connect your device back.


Method 2:

Release and Refresh IP Address

Click Start and type cmd, right click cmd and choose run as administrator. 

In the black command prompt window, type the following commands and press Enter after each:


1/  netsh int ip reset c:\resetlog.txt
2/  ipconfig /release
3/  ipconfig /renew





Now test to see if the issue has been resolved.



Method 3:

Remove Static IP

Press and Hold Windows key and press R. In the run dialog type ncpa.cpl and Click OK


Right click on Local Area Connection if you are using wired internet connection or Right click on Wireless Network Connection if you are using Wi-Fi. Click on Properties in the drop down menu.


Double click on Internet Protocol Version 4 (TCP/IPv4). Select Obtain an IP address automatically.

Select Obtain DNS server address automatically. Click OK > OK and close all windows.

Problem is I turn the computer on and I get this message and I can use the computer for day and not get this message. But if I turn computer off and some days later turn the computer on I than get this message.


I'm not sure why I'm getting this message.
