    How to tackle IP address conflict issue on Windows Vista?

    While I am using wireless internet connection on my Dell Inspirion laptop running on Windows Vista, it displays the message ‘can’t connect to DNS server as there is IP address conflict’. How can I resolve this issue?

    To fix this issue, you should first of all click on the ‘Start’ button and then on ‘All Programs’ option. On doing so, you can find the ‘Accessories’ option from the given items. You should click on that option to find ‘Command Prompt’. After that, you should right click on the ‘Command Prompt’ and then click on the ‘Run as Administrator’ option. You can then view Command Prompt window on your screen. You should first type ‘ipconfig /release’ on that window and wait for the prompt. Then, you should type ‘ipconfig /renew’ on the same window. At last, you should check whether the issue get resolved or not.

    Hello my friend,

    If you are getting this error too frequently then you can make a batch file to execute all commands simultaneously.
    open notepad
    and type these commands sequentially
    ipconfig/flushdns
    ipconfig/release
    ipconfig/renew

    then save it as .bat file extension.

    whenever you face ip conflict issue run this file.

    ALL THE BEST.

    here are the steps to tackle it...
    1-Click the "Start" button in Microsoft Windows.
    2-Click on "Run" and enter "cmd" into the pop-up box.
    3-Type "ipconfig /release" into the command box. This will cause the system to "flush" your old IP address.
    4-Type "ipconfig /renew" into the command box. This will cause your system to assign a new IP address to itself and will resolve the IP address conflict.

    Hello,

    If you are getting an IP conflict message than that means

    That there is another computer in the network which have the same ip as that of your computer.

    Now to resolve this issue you need to change the ip address of your system.

    To do that open the command prompt and type "ipconfig/release".

    This will delete the old ip of your computer.

    Now to assign a new ip address to your system type "ipconfig/renew" in the command box.

    Now you can assign the new ip address to your system.

    Make sure this time you don't put the same ip address .

    -Regards

    Re: How to tackle IP address conflict issue on Windows Vista?

    This problem, though rare, can occur because of the following reasons:

    1. Two computers are assigned the same static IP addresses
    2. One computer is assigned a static IP address that falls into the DHCP range for the local network and the same address is assigned to a computer by the DHCP server
    3. A laptop is put into sleep mode and then turned on while connected to another network that uses the same IP address
    4. If you have multiple network adapters, it is possible for a to have an IP address conflict with itself

    How to resolve an IP address conflict

    There are a few ways you can go about fixing this problem. I’ll start with the simplest and move on.


    1. Renew IP Address – You can release and renew the IP address for your computer using the command prompt. Read my previous post on how to renew an ip address
    2. Reconfigure Static IP Address – If your computer is using a static IP address, it is best to try and use a different one in the same subnet. One way to check to make sure the one you are picking is not already being used is to simple ping the IP addresss (ping x.x.x.x).
    3. Use DHCP – If you don’t need to use a static IP address, it’s best to simply choose DHCP instead of manually configuring the IP address. The server will know which addresses are free and which are taken.
    4. Update firmware – In some rare instances, the actual DHCP server can malfunction and assign more than one computer the same IP. In this case, it is best to try and update the firmware on your router.
