Windows has detected an IP address conflict

Hi Ronald - thank you so much for a detailed/throughout response. I don't mean to sound paranoid, but my question - how likely is it that someone else installed software or a piece of hardware that caused this notification? I have not installed any new software whatsoever on my laptop recently, and only one of the two protocols was checked when I looked at the network settings. Moreover, I work from a space shared by multiple companies working off the same wireless connection, and sometimes leave my laptop unattended for an extended period of time. So is it possible in some rare cases that the message could be more serious than a simple malfunction within the machine/indicate something more malicious?

Would be very grateful for any advice.

I did not have this problem until my XP computer stopped working and I had to get a new computer with windows 7 on it. Now I have two computers running windows 7 with a Verizon jet pack. I don't know how to assign a new IP address to my laptop.  I think Microsoft should fix this problem with a update.

After reading many pieces of advice while not being a tech geek, this appeared to be well-written, credible, and simple to try.  IT WORKED!!!  Thanks so much Ronald!

Hi,

You might experience this problem if the IP address is already in use on the network .You will have to reconfigure a different Ip address. This occurs when two computers on the same LAN network end up with the same IP address. When this occurs, both computers end up not being able to connect to Network resources or perform other network operations.

This problem can occur because of the following reasons:

Two computers are assigned the same static IP addresses.

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.

A laptop is put into sleep mode and then turned on while connected to another network that uses the same IP address.

If you have multiple network adapters, it is possible for a to have an IP address conflict with itself.

Please follow the below troubleshooting to resolve the problem:

Method 1 : Renew IP Address. You can release and renew the IP address for your computer using the command prompt.

1. Open Command Prompt and type IPCONFIG /RENEW.
2. Hit Enter.

Method 2: Reconfigure Static IP address

If your computer is using a static IP address. Try and use a different one in the same subnet.

Please follow the below steps:

1. To run Netsh click on start then type Run in search**.**
2. Type Cmd in the run box and hit Enter.
3. When the command prompt comes up type Netsh.
4. To change the Local Area Connection TCP/IP settings type the following command:  interface ip set address name=”Local Area Connection” static 192.168.10.42 255.255.255.0 192.168.1.1

 Changing the DNS IP address is almost identical as the procedure above, type the following command on the Netsh prompt:

interface ip set dns “Local Area Connection” static 192.168.1.1

To Setup WINS, type the following command:

interface ip set wins “Local Area Connection” static 192.168.1.1

To set the network properties to obtain the IP address from a DHCP server, type the following command:

interface ip set address “Local Area Connection” dhcp

To set DNS to obtain IP address automatically type the following:

netsh interface ip set dns “Local Area Connection” dhcp

Please perform the troubleshooting and reply with the results. I will be glad to help you further.
