Can you ping a computer based on its IP? (Or rather, can your DHCP client reach the DNS server?) – Hennes Apr 16 '13 at 12:17
yes i can ping my pc ip address and default gateway. is also ok. – prasanthi Apr 16 '13 at 12:20
Well, would be ok. It is localhost and will work even without network cable. But can you ping a computer outside the LAN on its IP? E.g. ping If that works then you have a working Internet connection and probably a resolver problem. – Hennes Apr 16 '13 at 12:22
You mention the default gateway is (localhost loopback) in your comment but your original post shows Can you clarify that the actual defualt gateway is? Seems odd that DNS server would be but without more info, that may remain a mystery. Can you provide the results of ipconfig /all and post into origianl answer? Ping an external site like or by IP for a known address like (Google DNS) Also try rebooting the router and modem if you have not done so recently. – Dave M Apr 16 '13 at 12:24
Is there another network between your router and modem? If not, it seems unlikely is providing DNS, given you're using the range Try a different IP in the DNS server field, e.g. – Marcks Thomas Apr 16 '13 at 12:32

Unless you are running your own DNS server on the same LAN, and you gave that DNS server an address of your problem is definitely due (in part at least) to the fact that you are using as your DNS server address. Why? 10.x.x.x is a private internal IP address and reserved for LAN usage only. It is not an address that would be used by any publicly accessible DNS.

As recommended in the comments, if you change your DNS server address to (Google's public DNS) or (openDNS address) you should have no problem accessing the internet. Your best bet would be to put one (or both) of these addresses in your router on the DNS settings page, rather than setting them manually on any of the computers.
