Windows 7 / Dell XPS 9000 / Hard Wired ( NO hub or wireless ) I keep getting an error that reads. Another computer on this network has the same IP as this computer. Contact your network administrator. I have contacted them and we have reset IP address checked pc setting installed new modem and I still get the error. I have empted dnc cache cleared all histories unplug and restarted PC setting are to acquire IP automatically

Sir, try to get new ip address by : Start --> Run... ---> CMD ipconfig /release ipconfig /renew Regards, MCP | MCTS | MCITP

Windows will detect IP conflicts by sending out a gratuitous arp. If another machine on the network responds that it already has the IP in question, Windows will advise you. Most cases, you'll find that yes, when you receive this message, there is another host on the segment with that IP. However, consider this...if you have a loop in your network (maybe by having two layer two switches connected to each other improperly), its possible that your machine will send and receive these types of messages to itself, thereby producing the same message, when in fact there is no conflict of IP.Guides and tutorials, visit ITGeared.com.

I tried this last night and I still have the error today. Any other ideas Thanks

I only have one machine hooked up and it has ran great for a year plus this has just showed up.

Hi 36chevy, Is it a domain-joined computer? Or a stand-alone one? Try change the computer name and see the result.

Changing the pc name seems to have worked I would have never thought of that. Thank you

Still need some help it came back after a day just can't figure this out!!!

Sounds like the conflicting machine is only on the network intemittently. During a period when you ARE getting the error message try this... 1. Run ipconfig in a command prompt window on the complaining machine and determine the IP address. 2. Now, turn that machine OFF. 3. Go to another computer on the network and run "ping IP_address" in a command window. 4. A respone means that the conflicting machine is REALLY THERE ON THE NETWORK 5. Go find it!

how is it setup? domain network? Are the Ip addreses assigned by dhcp? Sravan

I am having the same issue at my work with several computers (All Windows 7 Pro). These computers are all connected to the domain and connected via a wired interface. After checking DNS I see there are no duplicate entries for the IP address in question. Any ideas from anyone? It does not affect the users performance or functionality but I get calls every time it happens.

I have a similar problem ("Window has detected an IP address conflict") that has emerged only after a new Macbook joined my home network. In addition, the new Mac loses its connection if there are 4 or more other computers connected. I have a Netgear modem/router with 4 ports, but all computers connect wirelessly and my understanding is there's no limit on the number of wireless connections. But is there a limit to the number of IP addresses that can be or actually are allocated? Using ipconfig or ping is all well and good on the PCs on the network, but what's the equivalent for the Apples? If the solution is to manually set the IP addresses on the Macs, how is this done? And how do I set the IP range on the Netgear (if I need to)?
