Server At Google Can't Be Found Because DNS Look-up Failed
Nov 17, 2012
My wireless internet at uni is showing up with two errors, when its connected it will come up saying that there is an ip address conflict then it will work for a short time then show this message when I try to load a webpage:The server at Google can't be found because the DNS look-up 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 accessing the network.

Everytime i try to go to a site that uses a google server, i get the message "The server at www.google.com can't be found, because the DNS lookup failed. DNS is the web 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 accessing the network."

I have just gone through hours of tech support with my ISP and still cannot seem to get online. Problem is the same as recent posts by jerguy1928, with message "DNS lookup failed...." coming up in Google Chrome. Both IE and FF just say cannot connect.Running Windows 7 on laptop. I have tried alt DNS settings (Google and others), all the CMD suggestions, disabling firewalls etc, etc! Other computer in house connects just fine.Ping works fine. Really, there appears to be no reason to not be able to connect - since I am actually connected!

MGMcc solved my set up problem with my KDL-32ex713 which (i've swapped for a new model - its a long story). I used exactly the same ip addresses for the set up on this KDL-373x524 and got messages "wireless device found, local access failed, internet access failed". As my router and pc are the same as last time why the set up doesn't work this time and what I should do?

I recently bought a Sony Bravia HD TV with wireless internet capabilities.When I try to connect to my wireless internet. The TV finds our wireless router name, but when we try to finally connect wirelessly it gives the following message: TV wi-fi found, local access failed and network access failed. The router we have is a Actiontech PK500.On the TV we have three differant ways for the tv to locate the router they are by scanning, the WPS button and by entering the WPS pin. We've tried all three and got the above message.

My computer's virus protection expired so I Googled a free one and downloaded it without doing much research on it. It contained a virus and now it's disrupting my computer. I ran Microsoft essentials security and found malware and it removed all threats. The virus is disrupting my connection to the Google server. I cannot use google web, images, or mail but I can maps. I tried following the steps suggested here but my host file name is different and contains different information.[CODE]

I've been trying to connect to a particular website for a couple of days now, but always get "Server not found" error messages in Firefox. I have tried connecting on IE and Chrome as well, along with the 2nd computer on my wireless network. No luck there either though. I have been able to connect to any other website just fine. Between the two PCs on my network, I'm running Windows 7 and Windows XP.The website in question is currently up and they have said that no issues have been detected on their end and that it might be a DNS problem on my end.

recently I had some malware on my Windows XP Professional (version 2002), so I followed a guide at Bleeping Computer [URL] to get rid of it. Problem is, for some reason, after I finished, I could no longer access the internet!When I try, FIrefox gives me their "could not connect" message: "Server not found. Firefox can't find the server at [site]." Check the address for typing errors such as ww.example.com instead of [URL]"When I try to log into MSN, the troubleshoot says I have a problem with my DNS and Key Ports.I'm not good with computers so I Google'd and found some ping-ing instructions. When I tried to ping [site], I get: "Ping request could not find host [site]. check the name and try again." This happens regardless of the site I use.Lastly, I tried "ping 127.0.0.1" from a troubleshooting site. It gives me: "Pinging 127.0.0.1 with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

I have a Windows XP laptop and a Windows 7 desktop. The desktop has no wifi support, I had built it myself. To get internet on my desktop (used for games), I had connected my laptop to the pc, and the laptop picked up wifi from my AT&T gateway in another part of the house. ( I can't move the gateway currently) I have been wanting to connect the desktop to a router/repeater/bridge that would pick up my gateway signal, therefore eliminating the use of the laptop. I also have an Xbox right next to the pc, so I din't want to get an adapter because then I would have to purchase two, so I picked up a a wireless n router with 4 ethernet ports. ( then I could connect both systems using 2 ethernet cables) [URL] I knew when purchasing the router that it had repeater/bridge support. Currently, I have it configured as a wifi bridge. I can connect to it via my laptop, on the wireless networks page, it shows my gateway signal, and the bridge/router, so I connect to the router. It says I have excellent connection, but I can't connect to the internet? Using Google Chrome, it says DNS lookup failed. I can't get on any website, only the router's config page, which is 192.168.1.1. I also connected the router to my pc, and when troubleshooting it says DNS server not responding, may be non existant or incorrect?

Trying to set up remote access to webcam. Signed up with dyndns.org for Hostname, but when I try to set up the DDNS Service Settings in the webcam firmware it continually gives 'Bad reply from server' and I'm pretty clueless when it comes to networking! As far as I can see it requires a User name and Password plus the newly acquired Hostname as shown [URL]

I have a little problem with my ASA 5510 version 8.2(1) with a IAS server RADIUS for strong authentication.
I have configured a double authentication for my client to access SSL portal:
First authentication: AD serverSecondary authentication: IAS for my token SAFENET ALADDIN The server IAS is declared on a W2K3 and it's standard.
The problem I have is that after more than 24hours of unutilization, when i try to log in, my authentication failed the first time and then the other tries work fine as long as I use it in a period of 24hours.
I first thought about the timeout so i tried to put a "timeout" of 15seconds for AD and IAS servers and a "retry intervall" of 3 seconds, it doesn't change much.
Is there a tool/option in the ASA to check connectivity with the radius every 1h for example.

We are experiencing a lot of these RADIUS failed to respond messages on our WLC's leading to a lot of RADIUS server hopping within the WLC.We are using Cisco 5508's, 1142 AP's and a Microsoft NPS RADIUS backend. SSID is WPA2+802.1xThe first workaround to this problem was to disable aggressive failover on the WLC. But this is only a temporary fix, because in the end, there will be more than 3 consequetive clients, failing to authenticate to the WLAN network. As a result, the WLC will swap to the 2nd RADIUS server configured.When we dived into this a little bit more we saw the following messages being logged on the RADIUS backend at the time we saw the RADIUS messages on the WL:Event ID: 6274: Network Policy Server discarded the request for a user.

2 days ago, my laptop was connected to my router and working fine. But it then randomly disconnected and haven't been able to connect back since. I am using an ethernet cable to access the internet, and have tried many ways to try and resolve the issue but nothing is working.
I have a Dell L501x (Win 7 64-bit) with the Intel Centrino 1000 BGN wifi card. I have restarted the router and modem and disconnected all devices and tried reconnecting, but to no avail. I have tried updating the drivers, system restoring and using safe mode (with network) but nothing works. The modem and router are working fine as other devices connect and access the internet, it is just my laptop that cannot.
I am sure it is not a hardware issue as the card detects all the surrounding networks. The troubleshooter only says "An administrator profile failed to obtain an IP address from the DHCP server.
