Here are some tips

check LAN card driver itâ€™s proper install or not
check LAN card itâ€™s enable or disable (always enable)
check IP address, subnet mask, machine name and work group
check LAN security in O/S firewall itâ€™s stated on higher you change lower status.
check LAN cable, IO port and switch/hub port
check BIOS setting - LAN card enable or disable (always enable)

All parts and settings checked ok, ping another machine in network itâ€™s replayed or not,
Check your machine and network for virus with updated antivirus.

RE: LAN Connection

The host which does not get connect may have the same ip address of another host in the network

No connectivity will concer with both Physical & logical problems.
Just check will it properly connected via Cables Connector & lan Cards.
Then check is it in same subnet (TCP/IP configruration) & workgroup.

RE: LAN Connection

Following are the troubleshooting steps that could be tried

1) Check the
IP first (Start --> Run --> cmd --> ipconfig).

If you get Windows IP configuration message after entering ipconfig

check for the network adapter status in device manager (Start --> run --> devgmgmt.msc).

2)
Ping 4.2.2.2 ( 4.2.2.2 which is a Public DNS Server) if you get replies DNS resolution is not the problem.

If it fails try ipconfig/flushdns and then ipconfig/registerdns.

3) Ping www.anywebsite.com --> If it times-out try netsh winsock reset catalog
Reboot the pc.

4) If the above steps do not work you will need to uninstall and reinstall the TCP/IP stack.

RE: LAN Connection

Sometimes the problem persists in the Type of Cable.

Whether it is a cross cable or a straight cable.

Sometimes the LAN is connected in the computers but will not be able to ping the system.
