The problem persist... :-(

I'have reinstalled the O.s. but 2 days ago, the problem was reappear...
I have seen with "Netstat" and there were 2 connection to external Ip in the port 80, and the user doesn't surf...

With Hijackthis there were't any strange processes running

When you have the problem:

The network is still available? Can you ping the server?

Aren't you getting a duplicate IP address that may cause this hung?

If you use ping from the server to the client, and use arp -a, do you see the correct MAC address?

Can you run ftp to the server? What is the transfer rate?

Before the problem, what is the output of netstat -s?

After the problem, what is the output of netstat -s?

The network is still available? Can you ping the server?

- The network is stilla available, but in the tray the icon's network is disabled (with the red cross)

Aren't you getting a duplicate IP address that may cause this hung?

- The ip is still univocal

If you use ping from the server to the client, and use arp -a, do you see the correct MAC address?

Can you run ftp to the server? What is the transfer rate?

You should also consider:

- A bad power supply may damage the components.

- Electrostatical/magnetic/network noise, consider moving the computer to another location where the problem is not presented.

If is a bad power supply the computer doesn't work at any time, in this case the problem happen at random....
