How about doing this for a working computer and the non-working one.

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Once again, please do this on one of the working machines, and the non-working one.

Start, Run, CMD to open a command prompt:

Type the following two commands:

nbtstat -n

ipconfig /all

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Is that the working machine or the non-working one? The DNS server address looks a bit odd, I'd expect that to be the same as the Default Gateway.

Why are you using manually configured IP addresses?

sorry,
Its a long time im not here to check all your help, i've go to NhaTrang beach to do some business, now i come back and need your help.

I m manually configured IP addresses because its will auto change IP to another class, ex : 169.254.x.x not is 192.168.1.x. I dont know why ???I changed DNS as u told the same DG but nothing happen, still working error "Request time out" some time when i use ping cmd with -t. The other PC is good working ( connect internet and Lan ) then i dont think switch error. As u said i take this PC working alone with networking and non-networking, i ping so still on the same.

The fact that you have a PING time out at all on a local connection indicates a physical issue. I'd try changing the cable, changing the port on the router, and reloading the latest version of the network drivers for the machine.

I change the cable, port in router and download the latest version of the network drivers for the machine but still the same .I will take it to the PC store maybe they can fix it.

By the way, thanks very much
