This continues to pop up on my computer. I have changed internet services. How do I correct this problem. "It says thatanother computer on this network has the same IP address as this computer. Contact you network administrator for help resolving this issue. More details are available in the Windows System event log." I do not know what to do.

Hi Champions05,

Do you have Service pack installed for Windows Vista?

I would suggest you to use the below provided methods and check - **Method 1:**You can get a new IP address for your computer. You might need to do this if you are having connection problems.

a. Click Start. Type cmd in the Start Search box, and then press ENTER. 

b. At the command prompt, type the following command, and then press ENTER:

ipconfig /all (there is a space between ipconfig and /)

The ipconfig /all command displays Windows TCP/IP settings for all your network adapters.

c. ipconfig /release in the command prompt and press ENTER. This releases your current IP address.

d. ipconfig /renew in the command prompt and press ENTER.

The DHCP configuration for all adapters will be renewed. To renew the IP address for a

specific adapter, type the adapter name that appears when you type ipconfig at the command prompt.

Method 2: If the issue persists and you do not have Windows Vista Service Pack installedthen you may refer to the below link and check if using the hot fix assists you resolve the issue -

Hope this helps.

    It would have been helpful if you had told us how you connect to the Internet, and whether you have more than one computer or device on a home network. There should be only one DHCP server on a network. The DHCP server has the job of handing out IP assignments to each computer on the network. Perhaps your modem or router has its DHCP server function turned off.

    Please post any error messages from the Event Viewer concerning IP address conflict or networking (Start / Control Panel / Administrative Tools / Event Viewer).  Here's how to use Event Viewer: http://www.petri.co.il/vista-event-viewer.htm.  Look in the System section.  There WILL be errors listed.  Click on the errors for more details, copy the details, and paste them in your next reply.  They will very likely tell us what the problem is and/or where to find where the problem is.

    Did you use Static IP addresses with your prior ISP?  If so, that could be the issue if the system is assigning the same address to two different computers or devices (or if the computers or devices are set to use these addresses and the new setup changed something (perhaps the router IP) to something already assigned to a computer or something else.  Make sure you are not using static IP addresses and let DHCP assign them for you (unless otherwise directed by the ISP for perhaps the router or some other network device).

    At this point, what we need most is the information from the Event Viewer - so get that to us as soon as you can.

    I hope this helps.

    Good luck!
