Thanks. We'll let you know when a new response is added.

Try using the port and cable on another computer. If it works with that computer, then the NIC on the problem computer is bad. If it still doesn’t work, replace the cable. If it still doesn’t work, try another switch port. Both cables and switch ports can fail.

first ping from laptop if it replied then your nic card is OK.,
Attach laptop directely to that switch port with new lan cable it it doesnot work, try another port and with try with another laptop witht he same faulty port.
Check port configuration shut down and enable port if it is error disabled.

    Guess the tcp/ip or winsock control files may have been corrupted. Try out this.... Click Start > Run > CMD Now type the following netsh int ip reset c:resetlog.txt and again type netsh winsock reset catalog Remember, for these above commands, SP2 is required Open Local Area Connection > Properties > click INSTAL, select PROTOCOL > ADD Now click on HAVE DISK, type C:windowsinf and click OK. In the list choose INTERNET PROTOCOL TCP/IP, and click OK. Click CLOSE. Restart your computer Thanks--

    Dear, as you tell that cable NIC and Port are Ok , Try to see the NIC property (Advanced: speed&duplex settings ) if it work as auto or half ....... sometime NIC drivers do this problem

    is your DHCP client set to started and automatic? how do you get your IP is it from a router that runs dchp? if the router provides the IP check the router on how many IP it is releasing.
