I just recently purchased my laptop so I am just learning. The message I got on the computer said, 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. What does this mean and is this something important I need to fix. I would appreciate any help in this matter.

    I see that message on my home network sometimes, and it's not critical.  If you have a home network, try powering off your router, waiting a few seconds, and powering it on.  If you're on a business network, consult with the network manager.

    This message means more than one computer is using the same IP address, which is resulting in a conflict.

    In order to resolved this issue, u must make sure that each computer/ network device is assigned with an unique IP address.

    Trying releasing an renewing the ip address of ur computer if u are using a DHCP based ip assignment.  Issue the follwing commands from DOS:

    ipconfig/release

    ipconfig/renew

    I get this message all the time. As far as I am concerned it is just an annoying pop-up that otherwise affects nothing. Unless you know it is causing specific problems don't worry about it.

    Really? Do you think all of us are posting about something that doesn't matter?

    "don't worry about it."

    Although we see you are trying to act like you are helping, you are really not. Why post here if you have nothing useful to say?

    Anyways... Back to the issue.

    This has happened quite a few times. I woke my pc from sleep to reveal that nasty conflicting ip address message and when I did another computer who was on a VPN was suddenly kicked off and locked out. Had to restart other PC and relogin to VPN service. The real problem here is that the other PC is a business PC and this affects time, pay and ability to save work which means this costs us money!!!

    Any solution to this?

    --About release and renew...

    Should i change the Link-local IPv6 Address because that is the only one that looks distinct? Also, how would one go about changing these local addresses safely? This is what i get...

       Connection-specific DNS Suffix  . :

       Link-local IPv6 Address . . . . . : (removed for safety? :p)

       IPv4 Address. . . . . . . . . . . : 192.168.1.3

       Subnet Mask . . . . . . . . . . . : 255.255.255.0

       Default Gateway . . . . . . . . . : 192.168.1.1

    Steve, I am using an HP netbook using Verizon Wireless Broadband service.  There should be no other computers using my network since my connection is digital and this is a home computer.  Don't know why I am getting the "windows has detected an IP address confliuct" message. I am using Windows 7. I know very little about this, but could it be my backup system, Mozy, creating this meeeage? Any ideas?
