I'm assuming that this machine is not part of a domain?
Check that your PC has both a preffered and Alternate DNS Server set up.
The addresses to these should be given by your ISP. This error may have resulted because the first DNS server did not respond an no alternative was specified.

If you are using a Dial-up Connection:
Go to My Computer>Dialup Networking.
Right-click your internet connection and select Properties.
A window will open - click the Server Types tab. Click TCP/IP Settings.

If you are using a broadband connection:
Go to Control Panel>Network Connections and select your local network.
Click Properties, then select Internet Protocol (TCP/IP).
Click Properties.

Select "Use the following DNS server addresses" and enter the desired DNS server in the space(s) provided.

I think your ISP is having a problem maintaining their DNS first thing to try is to use different DNS to check if it is the problem you can use Opendns.org service to check that out enter their DNS IPs as follows:

Preferred DNS:
Alternate DNS:

If you have a problem using this DNS you can check out their website http://www.opendns.com/start/
Test this in two or three computers in your network and compare their performance to the other.

The machine is not a DC but it joined to the Dc, and I already assigned the Dns correctly, it worked properly for last 4 years and it's the first time it happened, right now the system back to stable and I can do browsing, but why that hour I was getting that message. Does it because of the slow link with heave usage on it.

Well I think the error message was clear enough to tell us that it was a problem with DNS responding to your request that is why I suggested testing another DNS service.
