IP address conflict!

[jmoore2001]

My friend told me she had the following error:

Windows system error: there is an IP address conflict with another system on the network.

shes on some time of high speed connection offered at her apartment and running Windows XP, thats all I know. Any help would be great!

Just have her run these two commands.

Click "Start" -> "Run..." Type in 'cmd' (without quotes) and hit Enter.

Then type these in hitting enter after each command:

ipconfig /release

ipconfig /renew

and if that doesn't work, call the ISP so they can help (because there is not much else she can do)

Does she have NIC card and USB Modem Installed?
If yes you need to disable one of tham.

It means that Your IP is shared by another computer on the same network. Has nothing to do with nic vs modem nor your ISP. No two computers can have the same ipaddress on the same network. To correct, do as "dave" instructed.

If you still can't get on or renew you need to make sure you have DHCP enabled. To check :

Right click "My Network Neighborhood"
"properties"
right click Local Area Connection
"properties"
highlight "Internet Protocol (TCPIP)"
properties
clikc the button "Obtain IP address automatically"
Same for "Obtain DNS address automatically"
close all windows normally
re-boot

Upon restart:
Your system will then negotiate for your Ip with the router that serves your network.
If you still cannot get on it is likely that IP's are assigned statically and you must see the system administrator for access.

Though with Windows XP you shouldn't need to reboot. As soon as you click ok it will change and obtain the IP from the router.

When they started coming with built-in DHCP servers.

[smunzli]

but the router is not handing out the IP, the DHCP server is.

[davidamarkley]

If you want to get technical, yes... the DHCP server hands out the IP addresses, but the DHCP server is builtin to the router.
