One customer laptop reports .... duplicate IP address on the network (or some similar error)

IP conflict error. Simple home setup with a few users, nothing fancy. 1 pc, 2 laptops

Im going on site soon.

I dont think its a fixed ip address.

What the chances its the router? Im considering swapping it out

I will update the wireless driver.
Anything else to try?

Its either XP or Vista - I think Vista.

Thanks

Hi,

If all of them are using DHCP, not fixed IP addresses, sometimes it's as simple as having it request another address from the router. I had a power outage at my house last week (same scenario - home wifi, DHCP, just a few machines) and one of the laptops came up with a duplicate IP address.

I launched a command prompt, and did

ipconfig /release

ipconfig /renew

and it worked fine. A reboot would have done the same thing, but that laptop was serving our network drive to the rest of the house so I didn't want to interrupt that service.

Hope this helps!

Wireless connection. Its been happening for months to the end user.
So a reboot isnt going to cure it.
if an IPConfig release / renew doesnt - what will?

The location was a small shop, I said home as it appeared to be a very simple setup.

I connected another router and when I connected only a PC and a mystery cat5 cable the error occurred.

This ruled out all wireless devices.

I found out that the mystery cable was going to a credit card machine.
It was bullying the other clients I think.

I reserved an IP address for it high in the range via the router and problem solved !

Thanks for everyones opinion as it guided me to the answer.

Another case solved.
