Try to uninstall the driver and reinstall it. leave the DHCP on if you have any DHCP server in your LAN.

If not try to setup static IP and check if you can ping any other Lan client. it might be your DHCP server the issue.

Try disabling and re-enabling your DHCP Server or just switch off/on your DHCP Server device.

First start by going into device manager and see what it shows?

Open command prompt type ipconfig /all post results

Lets see if the device is active or not first

Device manager is normal, no yellow !
ipconfig/all results: wireless connection is ok, LAN: media disconnected.
Tried disable and then re enable again, but still not working.

This laptop belongs to another user before and now another wants to use it, so I changed the name of user on server sbs03, then when i tried to use wired connection to connect the computer to the network to apply the new name on the laptop then it shows the messsage above because network cable is unplug.

As I said uninstall the LAN driver would probably solve it. not just disabling and enabling it.

when you open network connections what status does the lan adapter give you?

When the ethernet cable is plugged into the laptop what lights if any are on?

sounds like your ethernet port is bad. Did you check the lights to see if they are on when plugged in? Unplug cable then plug back in see if any lights come on.

Also you may need to go to the manufacturer to get an updated driver to install with

Have you setup a static IP ? try to do that and ping any other client machines in your LAN. if that didn't work either then you either have a corrupted LAN Card or a bad cable.

First for easy troubleshooting, try changing the cable with another short one and plug it a close device and try to ping it. if it works then it's the cable.

If not then it's a LAN card issue.
