Windows System Error – “IP Address Conflict”

Few days ago at work, two of the computers from the office kept showing a Windows message “there is an IP address conflict with another system on the network”. Now this has never happened to any of the computers before, and there is a hand full of them. Also, they are all connected to a linksys router (not wireless).What the message means is that two or more computer have the same IP address, which has to be change. No computer can have the same IP address, and this was caused most likely by the router (either the company providing the internet having trouble or the actual router malfunctioned).


To fix this you will have to figure out which computer is causing the problem, by trail and error.

  1. Pick a computer
  2. Click the Network Connection button located at the lower right corner of the start toolbar close to the clock ( or go to Start>Connect to*>Choose your connection).
  3. Click on the Disable Button.

  4. Once the connection is disabled, re-enable it the same way.
  5. If it does not enable, and it can not assign an IP address to the computer go to the other computer
  6. On the other compute, follow Steps 1-4.
  7. With the 1st computer’s connection being disabled, this one will not give you trouble and should re-enable.
  8. Go back to the 1st computer and re-enable the connection.
  9. In the same connection window, click the Support Tab on the top.
  10. Compare the two IP addresses, they should be different.
    If they are not, restart the computer ( it shouldn’t be need to).

Note: Connect To* – If you do not see Connect To in the Start listed,

  1. Right click on Start
  2. Click on Properties
  3. Click the Customizable Button
  4. Click the Advanced Tab in the new window
  5. Scroll to Network Connection
  6. Check the “Display as connected to menu”
  7. Click OK and Close out of it.

    This could all be solved to begin with if you simply used static IP’s, which most medium to large businesses do. Then you don’t worry about conflicting IP addresses because the router’s not assigning them; you are.

    Saves a lot of time and headache in the long run.

    Yeah I know, but it’s not even a medium business. Basically whoever has any kind of computer knowledge fixes them, and we don’t even have a service for them. Thanks for the comment.

    Ah. Okay. So no dedicated IT guy? I guess that would make it a little more difficult.

    Nope no IT guy. The company is very small, and having an IT guy, even just once a month service would be too much of an expense, especially in today’s market. And yes that makes it more difficult.

    how many users are in your network?

  6. ehacks on

    Normally there is 2-3 users, but sometimes it can go up to 8 users. It all depends on how many people show up in the office.

    Hi – I am regularly getting IP address coinflict pop-ups. I have a lap top in my apartment. I have no router or cable. I think I am hitch hiking on an office building across the alley from me. Would this be causing the pop-ups ?
