I have problems accessing most websites, only a couple work (grooveshark, google, facebook). On almost all others I get errors. Here is what I got using different browsers:
Opera: This website is not available Unable to look up www.xyz.com
IE: This website cannot be displayed
Firefox: Server not found. Firefox can't find the server at www.xyz.com
Chrome: This webpage is not available. The server at www.xyz.com can't be found, because DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accesing the network.
Error code: DNS_PROBE_FINISHED_NXDOMAIN
I am using windows 7 64bit.
When I log in to my facebook account I can see most things, some photos and videos dot not show though. Doing a google search results in the search results displaying but I can't access the pages linked.
Obviously I do have an internet connection, all the other computers on the same connection work without problems (XP and 7, both surfing with firefox).
Here is what I tried so far:
- Turn off both firewall and antivirus
- Opened CMD as admin, typed
netsh winsock reset catalogand restarted - Turned the router on and off
- Checked for viruses using avira and superantispyware
Any ideas about a fix?
@Lupy - it's theoretical to answer this, but some DNS records are cached on your computer (for the sites you previously visit). Also, it should affect all computers similar way on the network, but due to DNS caching and no further information it's impossible to answer. – phoops – 2014-11-25T19:05:05.457
worked like a charm!!!!! – tim – 2015-03-05T16:56:32.597
1This worked great for me, but I am really curious why it worked. My Macbook (plugged into Ethernet) couldn't access an IP. If i ping it, it just times out or "not reachable". Same on windows. I go to my windows machine, run
ipconfig /flushdns. Now I can connect! And my Macbook can connect now too! How in the hell did flushing DNS on my other machine open the pipe for my laptop? – Steven Lu – 2015-03-10T22:04:06.327Would I be right in assuming these Google DNSs would be blocked in China? – hippietrail – 2015-04-23T08:07:15.823
@hippietrail Not blocked in China, but not reliable either. If the GFW starts redirecting gmail, for example, queries for gmail to 8.8.8.8 will also yield the redirected IP address. – Steve Blackwell – 2015-06-01T01:28:45.173
What if this helps but only temporarily? After a while all is broken again. Where to check? – Suncatcher – 2017-06-17T11:06:10.427
And in my case this command works only paired with
ipconfig /registerdns– Suncatcher – 2017-06-17T11:06:47.3231Thank you! That did the job! Can I just keep Googles DNS addresses? Also, how does something like this come about? It's not like I changed any settings... – None – 2014-05-10T19:57:23.663
Yes you can, it is intended to be used by anyone. Well I would guess that you were using your routers DNS and on cheaper routers DNS sometimes breaks so you have to restart your router. This is usually due to limited memory on these things on inefficient firmware, thus I would generally advice using either something like Google DNS or just your ISPs DNS servers manually. You can even setup your router's DHCP to set DNS to Google's or your ISP's. – phoops – 2014-05-10T20:30:41.817
1If the routers DNS really broke, why could I access some site but not others and why where other computers connected to the same router not affected? – None – 2014-05-10T20:34:37.303
