IP address conflict with another system on network??

If you can, read our FORUM STICKY. It notes what setting to use on your WIFI ROUTER to avoid the more common reasons for this issue.

Having a post hidden in a post keeps it from being noticed.

Maybe you'd want to create a new discussion and leave us know details

The 3 laptops are using what Operating systems.

What is your setup?

wall > cable/dsl modem/router > wireless router > wired/wireless

Update the firmware in the wireless router, at manufacturers website. Make and model number sticker on wireless router.

Broadcast SSID
Use WPA security

use nothing else.

Have the router use DHCP server. It will automatically assign an ip address so two computers cannot have the same ip address. I have three laptops and once in a while, someone will not log in for a while. When they do, then they get the lower ip address. My laptop will then be assigned a different one.


If you don't get it working, start a new post.

on both VPN points and before you use the key encrypt it with an encryption program then paste the encrypted
key into both vpns as a preshared key and see if that helps you will also want to turn on ipsec and cruise over to
http://www.microsoft.com/technet/network/evaluate/technol/tcpipfund/tcpipfund_ch14.mspx
and squrit some visine in your eyes before reading cause it will be a long night you also need to know how to route ipsec incoming and outgoing example rules
use the add wizard to simplfiy things
always start with ANY IP ADDRESS and then use MY IP ADDRESS and then build from there the loopback is an option also as a DNS name just type loopback ipsec is funny when using DNS names and for every entry you use always bring it back EXAMPLE any ip address to my ip address THEN THE NEXT ONE WOULD BE my ip address to any ip address and you also have the option of using
the preshared key you created in ipsec also and make sure you move it to the top above kerbos and you can play with ipsec and make all kinds of keys and different negotitation combonations or include them all but on your routers you need to use PRESHRED KEYS anyways so no one can walk in through your security door gateway if you do not have a remote endpoint the router wont connect like my setup i use it but my endpoint is my router and the other endpoint is my ip address which creates a vpn connection from my ip to my router then ipsec secures all traffic from and to them endpoints tunnel layer like dual tunnels so IF hackEr wanna be A trys to worm there way in to the tunnel they become TRAPPED and cant navigate past or out of the tunnel but you have to be specific with your route destinations in ipsec and once you get your routers communicating from endpoint to endpoint between each other and use long keys and a high encryption tool on your key
and a key can be anything from your name to numbers and letters to numbers and symbols and so on as an example lets say this is my preshared key MyKeYrOuTerS*Y*S@R3MoTeLoCaTi0n that key already has a strength buy how many letters numbers and symbols i used
then you take your key and run it through an encryption tool that will encrypt your key you made then you paste the encrypted key into your preshared keys spots on the router and in IPSEC if you do it right you will be able to access all over your points but if you have something wrong in ipsec you wont be able to connect to the internet or your routers and then all you have to do is disable ipsec to get your connections working again then undo what you did to stop the connection
it is helpful to add your endpoints one at a time and then try your connection and make sure you add your router gateway as as a RULE as well as your IP you use mmc.exe in the run command to open the mmc and click files\add and remove snap ins to fire up ipsec load the local computer for ipsec monitoring
the tech net address will help you with ip sec

Is this common with the conflict problem. If so How do I fix it

i am having a problem here at my work place,,every now an then window pop ip conflict.an there is no ip address that is the same on the system,but when my ISP are not at work i dont see the message everything work fine .please help me..

It's unlikely many will arrive here and if 46 posts didn't fix it, your issue is unique and deserves a new post all your own.

I have three computers on my network: one XP, one W2KPro and one '98 (I know, I know ...). Only the XP was affected.

I traced the start of the problem to the installation of Windows XP update KB930916 on May 11. I uninstalled that update (left the security update installed), and the problem appears to be gone.

Hope that helps.

it started happening after i bought a new wireless card ( the other one broke )

Start, Run CMD and press enter.

type this...

IPCONFIG /RELEASE ALL

Now exit that and do a full reboot. Sometimes that does it.

i switched to linux (ubuntu)

ok, sounds quite silly but im in need of some networking help.
I have two Network connections on my computer
#1 is connected through Ethernet to my Modem.
#2 is connected to another computer in the house that i want to share the internet connection with.
For some reason when i click (Allow other Network users to connect though this computers internet connection) on #2 the
Connection number #1 disappears and cannot browse the internet.
hope you guys can make some sense of that and get back to me ASAP???? thanks,

Hey, im getting the ip adress conflict error too, but when i go (CMD ip config) all my adresses come up as blank, ie: 0.0.0.0

Is this a virus maybe? Or something else?

If not please start a new discussion for you since this is now buried on page 2.

go to your start button.
choose run.
type in "cmd" <enter>
a DOS box will pop up.
type in ipconfig /release <enter>
then type in iponfig /renew <enter>

wait patiently until a new Ip address is generated.

no worries mate.

I have found a fake alert from email. It was detected by my anti virus but not healed.I get the same message Ip conflict with system on network.
I updated my aniti virus and ran spybot problem gone.
This was the path
