Windows Has Detected an IP address conflict

[Page]

We have been getting this sometimes at work on the wireless router on one or other of the machines for the last week or so

To date we have ignored it because often these things go away but this time it has not

What can I do about it

That means that there is a conflict between devices on your network. They are using the same ip address (which they can not do) so one or more devices will not connect to the internet / network

you could do with finding the problem system's and assigning them new non conflicting ip addresses

your router assigns an ip address to each computer and each one should be different. It may only be a tempory thing though when the computers are first booting. Is there any problems with the network?

You can easily check IPs by logging onto the router but for someone who doesnt know how to do this then the next easiest method is to:

Click Start > Run > Type 'cmd' without quotations.

In the panel type 'ipconfig' and check your IP address. Do this for every computer and check there are none the same. If there are then you'll need to go into the router and change some settings or go to Control Panel > network connection on one of the computers, right click the Local Area Network, click TCP/IP then properties and assign an IP manually. It will need to be exactly as it was before but with a different last number (between 2 to 254).

More details can be found by googling ' manually change IP windows xx' etc

Don't ignore it, as all bets are off if you get two IPs the same on a network and you will likely see some very strange errors and possible data corruption.

Sounds like you have a device with a fixed IP that is within the DHCP scope. A 'scope' is a range of IPs that a DHCP server can hand out, and will do so even if a fixed IP exists.

Normally this is dealt with by limiting scopes, so a typical set up would something like:

192.168.0.1 - 30 fixed IPs for servers, printers, gateway etc.

192.168.0.50 - 100 DHCP scope for workstations

Is your router the DHCP server? They vary in their ability to limit scope or allocate fixed IPs, so see what's available in the router DHCP settings, with a view to keeping fixed IPs separate.

I agree with KM-Tiger, it sounds as though there is a static assigned IP address within your DHCP range. Bear in mind that if you do go roaund checking IP addresses on devices that it may be on networked printers, servers and other networkable devices not just the PC's themselves.

More information on DHCP and how to re-assign or reconfigure your router and / or computers can easily be found on Google or shoot us back here and we can talk you through it step by step.
