Windows 7 DNS server not responding (Network Steve Forum)
Windows 7 DNS server not responding
Hi !! Since two days my windows-7 laptop is not connecting to the internet. When i tried to troubleshoot the issue i got a warning that DNS server is not responding. But the internet connection exists. As data transfer rate is changing and also the torrentz is running. Only problem is for the web pages...I alos tried restoring the computer to all the previous dates but still problem exits. Can somebody help me... Thank you..
December 13th, 2009 9:28am

Hi, This issue can occur by incorrect DNS settings. I suggest you perform the following steps to troubleshoot the issue. 1. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. 2. Right click on the connection that you use for the local connection, and then click "Properties". 3. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". 4. In the Internet Protocol window, let's change the "Preferred DNS server" to 208.67.222.222 5. Click 'OK' twice to complete the modification. If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220. Meanwhile, I would appreciate your help in clarifying that if the network is based on a router or a DSL modem. If there is a router, please bypass it and connect to DSL modem directly for a test. Thanks, Novak

Just had this same problem. Installed Win7 Pro 64-Bit on December 16th. Hasn't activated yet (our admin is still sorting out the KMS server). Yesterday afternoon, my home wireless connection lost access to the Internet. Access to the LAN is fine. Finally determined that it's not resolving DNS. Funny thing is, even NSLookup wouldn't resolve anything, yet, the DNS servers were fine. Kept noticing two wireless connectoids in my network settings. "Wireless Network Connection" is my normal wireless connectoid and was connecting fine. The second was "Microsoft Virtual WiFi Miniport Adapter" and was showing disconnected (as I expected). But, I couldn't figure out where that second connectoid came from, so finally, I disabled it. As soon as I did, my DNS sprang to life! I'm not sure if the OS is trying to activate, and interferring, or if that connectoid appeared as part of a Windows update, but disabling it fixed it for me instantly.

I am having the same problem after I upgraded my Gateway desktop from Vista to Windows 7. My Win 7 computer is on a wired network and I was able to browse the net for a few mnts after the upgrade but started getting DNS Server issues. There doesn't seem to be any issue with the DNS server since other computers on the same network are able to access the internet. I have VZ FIOS coming in and I have DLINK DIR 655 router. A computer directly attached to DIR655 is able to access the internet. My windows 7 PC is attached to DI 604 switch (using the router as a switch). Nothing changed in network and it worked just fine with Vista. Only change is upgrade from Vista to Windows 7. I tried configuring the DNS server to 208.67.222.222 but that didn't help either. I appreciate any help.

Just to add a bit more details to my previous post, I verified network by attaching another XP laptop to the same switch and it works just fine. I am able to browse the net. There is no issue with the DNS server configured in the router or in network but Windows 7 isn't happy. Any help is appreciated.
December 20th, 2009 2:43am

I reinstalled Windows 7 and still intermittent internet connection issue remains. I called Gateway and they advised me to restore system to factory setting which is Win Vista. I asked them for the Win 7 network driver and they don't have any support for it (although they did provide upgrade DVD for it). It seems like Win 7 64 bit doesn't have a good network driver for Intel network adapter that is in gateway SX2800. I was hoping with Win 7 Microsoft would have better drivers but alas. Would anyone from Microsoft want to help (or I will have to load Linux on it)?

December 21st, 2009 3:05pm

Do you have your DNS server on your LAN subnet, or is it performing a DNS query to an outside public IP?Of course, I have to ask do you have any other AntiVirus/Firewall running then Windows Firewall? In either case, have you tried to disable the firewall to see how it reacts?
Free Windows Admin Tool Kit Click here and download it now
December 21st, 2009 4:21pm

Since it was working intermittently it can't be firewall issue. It can't be an issue with the DNS server since all other computers attached to same router are working just fine. To me it seems like a network driver issue and Gateway didn't provide me any driver except the one that is shipped within Win 7. I even tried the driver that I downloaded from Intel site but same behavior continued. Unfortunately I couldn't wait for Microsoft/Intel/Gateway to fix it and have moved back to factory installed Windows Vista and not encountering any issues at all. I am not happy about using the legacy OS but don't have time to debug things.
December 22nd, 2009 5:16pm

Do you have any VPN software installed on either system? I ran into a problem when I upgraded over Vista x64 to Win7 x64. 1 - I had to uninstall the VPN software and reboot the box. 2 - I had to open Device Manager, Choose View - Show Hidden Devices 3 - Delete any and all Intel networking components (actually you choose uninstall)4 - Delete the Microsoft 6to4 Adapter (it will be remade on the reboot)5 - Delete all the Microsoft ISATAP drivers.Reboot, and let the OS detect and remake the network adapters, 6to4, and ISATAP drivers. Install the network adapter...That's what I had to do to make the DNS not be so flakey. Also, instead of visiting the OEM site, I visited the Intel website and downloaded the latest driver from there. Worked like a charm.David Dracoules

Ok, so i just tried the solution provided by Novak but didn't get very far with it. So I played around a little more.

I dont get it, but if this helps anyone then this post will not be for nothing. gl all

Disabling "Microsoft Virtual WiFi Miniport Adapter" resolved my issue as well. Before disabling it, the wired connection worked properly but wireless would not resolve DNS, even when using NSLOOKUP. I could ping the Internet and browse by IP address so it was definitely DNS not working. Setting static DNS servers did not help.Victor S. - Enterprise Integration Solutions, RCM Technologies

Hi; I have an Acer One D250 netbook with Windows 7 Starter, which seemed to be able to connect wireless to anything and everything since I took it out of the box. However, sometime around the 20th or 21st of April, it suddenly lost that capability. The computer indicated that the problem was with the DNS. I have tried all of the remedies on this webpage, with no luck. Yes, I have changed the DNS numbers, reloaded and updated drivers, restored, disabled this and that, and nothing seems to work. It connects instantly to DSL. I have gone to a different location and connected via DSL...no problem. At the same time, I have gone to several other locations in this area where wireless service was available and I get the sameresults...no DNS. I have an old Dell laptop with XP and it is able to connect wirelessly, not just from my home, but from the other locations I took the Acer as well. All the routers are not bad, especially if other OS are able to connect to them...it is something to do with Windows7, I am convinced of that. I am wondering if being unable to connect wireless was a result of some glitch in a recent update? I get updates automatically; the Windows7 seems to be updating this or that almost everyday, whereas auto updates on my old Dell are disabled. There has to be something which occurred in the last week that would all of a sudden cause Windows7 to lose its wireless capabilities. Regardless, I use this Acer on almost a daily basis and I need to find out how to get it to be able to connect wireless again.

Hi Yes, I tried disabling the Microsoft Virtual WiFi Miniport Adapter, with no luck. Several times. This, besides confuguring DNS server and the whole kit and kaboodle. Nothing. As I say, connects fine via DSL, but on wireless...not! I beginning to get rather dismayed, as I bypassed some good buys on new units with Vista to buy the netbook with Windows7, mainly because the salesperson advised me that there was "no comparison" in regards to the Windows7's connection abilities. Meanwhile, a friend at work has a laptop with Vista and he has no troubles whatsoever. This just isn't right!

May 1st, 2010 11:42am

Novak, I have been having intermittent problems with DNS not responding. I tried your two DNS address solutions above, one worked for a day but then it goes out again and then I have to reset it. I have spent hours on the phone with tech support to no avail. For instance, this morning it was not responding after working all night last night. I reset to the DNS address above which seems to work the best "208.67.220.220" but then my boyfriend couldn't log on as it said their was an IP address conflict. So I reset the DNS to obtain automatically and it seems to be working fine. I have no problems with service anywhere but at my house where we just switched to AT&T DSL. It hasn't worked right since on my computer but my boyfriend's computer works perfectly fine. I am running Windows 7, he is on an older operating system. Any help would be greatly appreciated. I have tried numerous other things with tech support (too many to list) including disabling the firewall, clearing out the DNS and starting over, etc.

May 10th, 2010 6:30pm

I too am experiencing a very similar problem: I use a 2Wire DSL Router to connect one or two wireless computers and four or five wired Ethernet computers. The configuration worked fine with Windows 2000, which was upgraded to XP on the wireless machine while all wired machines ran Vista (64 Ultimate). Everything worked fine. I upgraded all Vista machines to Windows 7 Ultimate as well as the wireless machines. The Wired Ethernet machines see and connect to the Wireless machines fine. The Wireless Windows 7 machines connect as well as before to the Internet. But the Wireless machine, while it see's the other machines in the Workgroup, using whatever interface, Windows Explorer or the Network Connections interface, doesn't connect to the wired machines in the workgroup. All the machines have at least one account in common, using the same password. The wireless machine connects to the Router. When, through the network server on the 2Wire router, the wired machines are queried about sharable files, the same name resolution error appears. I have half-duplex file sharing, which I might be tempted to live with except that backup requires a 'push' connection. I have disabled IP-V6. The fact that I can resolve names through the routers 802.11G connection from the wired connections but not the other way confirms the physical link. I did try assigning the preferred DNS server as recommended. This is a NAT configuration using DHCP. The router, which certainly resolves the names of all the clients in the workgroup, generates a message "Cannot find 'file://192.168.xxx.xxx'. Make sure the path or Internet address is correct." An attempt to open nodes from the wireless node generates a \\computername is not accessible. You might not permission... The specified network provider name is invalid. This does appear to be DNS related. Nothing changed other the Windows 7 replacing Vista 64 Ultimate and XP on the machines connected through the router's internal 802.11G facility. The router was unchanged. This router, while it is in millions of homes using the ATT DSL services, is not on the list of DSL routers approved by Microsoft. But a change in Windows 7 requiring ATT customers to buy a new router and take on its support seems unlikely to be a marketing campaign. One message suggests that the wireless client machine is looking at the DHCP router as a server, but should have been fixed by assigning DNS resolution as suggested here.

I was on the phone for hours with Sprint my wireless provider and HP tech support and all of their help could not solve problem and then I discovered this forum and realized this is not a unique problem but a common issue with varios computer models and Internet providers.

Hi Novak, the first one didn't work, but 208.67.220.220 worked great. THANKS! However, I remember reading a previous post from someone who said your solution only worked intermittently. Well, since I checked out this forum only today, I guess time will tell. One other thing I wanted to ask was, on your 12/24/09 post, you advised us to check the "Validate Settings Upon Exit" box after entering the new DNS. I have not done that, since I saw that post after your initial post that told us how to resolve the problem. I am, BY NO MEANS, a tech guy, so I apologize for my ignorance and/or stupid question. But, what is the difference between checking that box/not checking that box?? If Novak's not around, can someone please assist me with my question? Should I check that box or not? Thanks to everyone... Hope to here from someone soon:)

Hi Novak and anyone else who may be able to help: Am using W7 64, I am constantly getting “DNS server not responding" when on WIFI but able to get a stable cabled connection. Have tried two different WIFI routers, switching the cable between the modem and the routers, and so believe it is not the hardware causing this problem. Moreover, this is a sudden change as previously did not have any problems. I have tried Novak’s suggestion of changing the DNS server to 208.67.222.222 and 220 but it doesn’t help. What is interesting is when clicking “additional troubleshooting options” the problem resolves itself but only temporarily. Have tried all other solutions suggested so far on this thread to no avail.

I did not want to uninstall Norton so finally I reset my firewall settings using the "restore defaults" option under Windows Firewall and viola! Back up on the Net. Will see how long the connection lasts . . . Control panel --> System and Security --> Windows Firewall --> Restore defaults

I had the very same issue. Do as Novak suggests and click "start" then type in 'ncpa.cpl'. Follow instructions as below to Internet protocol 4 and select 'properties'. You'll notice it may say "use dsl address" or similar - it may be 192.186.1.1 or 192.168.0.1 Type either of these into Explorer and which ever takes you to the router settings page is the number that should be present in here. Failing this you can try selecting - "assign dsl automatically" - both of these worked for me after trying everything. this pure guess work did the trick.

Just had this problem out of the blue yesterday. What seemed strange was that while I could not get on the Internet and all open browsers closed on me, I was at the time listening to radio on the net and that was unaffected. I shut down and hoped it would "heal itself" overnight. It didn't. And a couple rebotts didn't help either. I called my service provider and was told to powercycle my modem. Worked like a charm!

Hi, This issue can occur by incorrect DNS settings. I suggest you perform the following steps to troubleshoot the issue. 1. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. 2. Right click on the connection that you use for the local connection, and then click "Properties". 3. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". 4. In the Internet Protocol window, let's change the "Preferred DNS server" to 208.67.222.222 5. Click 'OK' twice to complete the modification. If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220. Meanwhile, I would appreciate your help in clarifying that if the network is based on a router or a DSL modem. If there is a router, please bypass it and connect to DSL modem directly for a test. Thanks, Novak Thanks it worked

Hi there, I have the same DNS server not responding problem in my LAN, Win 7 64. When I try to change the DNS address as Novak suggested, it gives me a warning: Multiple default gateways are intended to provide redundancy to a single network. They will not function properly when the gateways are on two separate,disjoint networks (such as one on your intranet and one on the Internet) Do you want to save this configuration? The IP address: 192. 168. 1. 123 So what shall I do, PLZ help!

Hi all, I had the same problem, so changed the Preferred DNS server as Novak proposed, which worked, with the first ip address: 208.67.222.222 This got the connection back, and I then deleted the number, re-ticking the Auto Detect box, and my connection remained good I'll definitely come back here for future Win 7 advice - Many thanks all

I rely on my computer for business and school so I had no choice but to go back to XP (which cost me a whole day of downloading), is there anyway to get my money back for the Windows 7 Professional I purchased?

Novak, I've attempted your solution, with no success. As far as I can tell, the "Microsoft Virtual WiFi Miniport Adapter" is not present in my system, so I have not been able to make use of that suggestion. I am becoming almost frustrated enough to cry over this, because this is pretty much a waste of a computer until it can connect most of the time. PLEASE HELP. I am, very rarely, able to get my new Windows 7 Gateway DX4300-15e PC to connect to to the internet through my wireless network, but it normally will connect to the network and fail to connect to the internet. Several PCs and other devices, wired and wireless, connect to the same network flawlessly (including my laptop, upgraded from Windows XP Pro to Windows 7). The router is a D-Link DIR-825 (operating in 2.4GHz mode), connecting to a Time Warner cable modem.

This issue is driving me nuts :-( I just got a 3G Router (Planet WNRT-625G) using a USB Modem to connect a couple of PCs thru a LAN connection. My machine is a Dell Vostro running W7 32 bits. At first it seemed to work fine but I started to get that error. Basically I have got 5 minutes of connection and then it goes off and eventually I have to plug the USB modem right into my box. I tried the 208.67.222.222 thing but it didn't work. I haven't looked at thte Miniport thing yet. I have tried disabling Kaspersky Firewall as well. Just to clarify that issue, when the system says that the "DNS Server is not responding" which DNS Server is it ? Should I have one ? My ISP's ? When changing the 208.67 I did it on my Network Connection but what about the DNS settings on the router ? UPDATE: I solved my issue. The problem was with my USB Modem, I had a new one which didn't seem to work a Huawei E1756C I guess a compatbility isssue. I changed it back to the old one, a Vodaphone K3760, and its working like a charm.

I am also experiencing this problem. Periodically I am unable to connect to the internet and every time when I click to diagnose it comes up that my dns server was not responding. This is very strange behavior because I can occasionally close the troubleshooter and it will work for a brief amount of time. But inevitably this issue comes back. I have followed the above steps outlined by Novak by setting my preferred dns server to 208.67.222.222, and I have also attempted to power cycle my cable modem, all to no end. I still get the same issue. What other steps can I follow to try and address this? Is there some configuration on my router that I need to play with? Do I need to contact my ISP and if so what specifically do I need to tell/ask them? Should I just downgrade to Vista (seriously not the preferred solution)? Thanks, N

We too have the same issue, seems Microsoft is not interested in giving a solution to this one! Even though a lot of people seems to be affected by this. Vista was one crappy OS, Win7, after the initial bursts seems to be more Crappier!!! Most of our users have moved to XP. We have been testing/using Windows 7 for over a year now and sill there no solutions for the network problems.. ... how long can anyone wait?
January 14th, 2011 5:51am

A temperory workaround, until MS comes with a solution which solves everyone's problem, is, if DHCP is been enabled then go to the wireless adpater properties and set DNS to manual and enter 8.8.8.8 or 208.67.220.220. Give OK and OK. Now connection will get established. But this is not stable and will go back to disconnected state after some time, inour case some 3 to 4 hours. We reverse the process and we get connecteed again. We have 3 Windows 7 and 2 Windows XP laptops connected to our Wireless router one Win7 laptop has this issue, we recently reinstalled the laptop and did a windows update also, but still issue is there, it just started some 2 weeks ago, might have been caused by automatic updates. Who knows? Hope MS comes out with a solution soon, from all the forums it is pretty obvious that most Win7 users are affected.

Hi, I have a DNS problem. I have done everything in this forum. It works at home when it is connecting to one internet provider(eircom) and it works anywhere else that uses the same provider. But when I am in my college home it will not connect, because we are using 'UPC' - a different provider. It seems that the laptop is 'locked' into using only one DNS server, does anyone know how I can fix this?? Any help at all would be great. Thanks
January 26th, 2011 1:26pm

Just had this same problem. Installed Win7 Pro 64-Bit on December 16th. Hasn't activated yet (our admin is still sorting out the KMS server). Yesterday afternoon, my home wireless connection lost access to the Internet. Access to the LAN is fine. Finally determined that it's not resolving DNS. Funny thing is, even NSLookup wouldn't resolve anything, yet, the DNS servers were fine. Kept noticing two wireless connectoids in my network settings. "Wireless Network Connection" is my normal wireless connectoid and was connecting fine. The second was "Microsoft Virtual WiFi Miniport Adapter" and was showing disconnected (as I expected). But, I couldn't figure out where that second connectoid came from, so finally, I disabled it. As soon as I did, my DNS sprang to life! I'm not sure if the OS is trying to activate, and interferring, or if that connectoid appeared as part of a Windows update, but disabling it fixed it for me instantly. I had the issue with "DNS server is incorrect or not working", and LAN was working fine. After reading these posts, I looked for the "Microsoft Virtual WiFi Miniport Adapter" under my "Wireless Network Connection", which had never been there before this morning. Mine wasn't hidden, though, so it was easy to find. I saw that it was enabled and disabled it, and what do ya know, my wireless internet started working right away. I think that it may have been result of an update as stated above. Lucky for me, I managed to get this resolved in just a couple hours after realizing the problem.

I have W2k3 AD (and DNS server) on my home lan. After setting the domain and stuff... my main Win7 x64 PC had issues with dns not responding?! I've done similar setup many times before, and this is the first time this happened. Tried everything suggested with no luck. Found the new solution on my own. It was the firewall problem on my server. Simply setting the both TCP and UDP ports 53 to allow connections resolved the issue. I hope this will help someone out there.I've seen things you people wouldn't believe...

Hey I had the same problem and after testing the chord using the solutions mentioned in this thread reinstalling the drivers and restarting the router and computer 100 times. I figured out a solution. It seems that if you have multiple computers on the network and they have File and folder sharing on it will set up a Network of it's own. My computer (Be on an Ethernet line) connected directly to the VPN that my roommates had accidentally set up by sharing files and folders. So disable your Network sharing by Control Panel -> View Network Status and Tasks -> Change Advanced Sharing Settings -> Turn off File and printer sharing & Turn off Network Discovery (This may cause you not to find any networks if you're using a wireless connection so just uncheck the first option).
January 30th, 2011 10:37am

Hi Novak The the reason why others cannot make it work because you have to do the Alternate DNS server as well "Preferred DNS server" to 208.67.222.222 "Alternate DNS server" 208.67.222.220 Now it will work

April 19th, 2011 10:51pm

Novak, Micro$oft has absolutely stuffed up its implementation of DNS on its recent releases, Vista and 7. People are advised to leave their network settings on auto, ie obtain ip address automatically and obtain DNS server automatically. Vista and 7 do not accept the DNS settings of many routers, but instead uses the router's IP address as the DNS server address. Of course, most routers do not provide dns services and will never provide an address for dumbo vista and 7... Come on M$, get your act into gear... it used to just work with XP and Win98, what happened with the last two? Are you just trusting Vista and 7 automagic? Well it doesn't work! Please fix it... I waste hours trying to help people change their DNS settings because the system is incapable of properly detecting locally router assigned DNS servers. Just fix it please! KAJAYR

I have the same problem and i have gone through all of the steps to resolve this, without any luck. So i called my service provider and after 30 minutes of waiting for a tech i finally got the answer that i usually get from my service provider...."it is a problem on our end not yours". So what i am suggesting is if anyone has the same problem you should contact your service provider before making any major changes to your system. Sure, try some of the steps that are mentioned throughout this forum but before you go and restore your computer to its original factory condition i suggest calling your internet service provider first. Good luck.

At the command prompt, type the following command, and then press ENTER: ipconfig /registerdns (there is a space between ipconfig and / ) 4. At the command prompt, type the following command, and then press ENTER: ipconfig /all (there is a space between ipconfig and /) The ipconfig /all command displays Windows TCP/IP settings for all your network adapters.

Hi, This issue can occur by incorrect DNS settings. I suggest you perform the following steps to troubleshoot the issue. 1. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. 2. Right click on the connection that you use for the local connection, and then click "Properties". 3. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". 4. In the Internet Protocol window, let's change the "Preferred DNS server" to 208.67.222.222 5. Click 'OK' twice to complete the modification. If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220. Meanwhile, I would appreciate your help in clarifying that if the network is based on a router or a DSL modem. If there is a router, please bypass it and connect to DSL modem directly for a test. Thanks, Novak This solution seems to be working so far. I have a registry fixer program that is constantly prompting me to repair (delete) faulty registry settings and I admit that I do not filter this much but just press REPAIR. I was afraid I may have deleted something important in my registry that made the dns work with my router. After changing the DNS setting from automatic, to the address given I have so far not have any failures. I'm still concerned however about the root cause of the problem, and I am wondering also if there are any disadvantages to the solution, i.e. having a single manually set dns server location vs an automatic setting. Thank you for getting me up and running. Are there any disadvantages to not being on auto?

It's gonna be your Wireless Card. Mine has the same problem. Already tried a lot of the steps that were told to you, It's due to the Wireless Card not working properly. I suggest you try to change it. If you have something that fixed it please share it.

So why 208.67.222.222 ???? Why specifically that one? What's the difference between all of them?

Disabling the Microsoft Virtual WiFi Miniport Adapter worked for me as well. It only took me about an hour to diagnose and resolve thanks to all the helpful posts :)

Hi, For all of you that couldn't resolve the problem using Novaks solution, i found another solution to the problem. I tried every solution mentioned in the thread yet nothing worked. Finally i managed to resolve the problem by bridging the wireless network adapter with my nforce controller, though that one remains disabled. do this to get it working: -> start / Control Panel / Network and Sharing Center -> Change Adapter Settings (here you will probably see something like "Local Area connection nforce controller", "Wireless Network Connection 'ur adapter'" and the "Wireless network connection Virtual Wifi miniport) -> disable the Virtual WiFi Miniport if you haven't done so already. -> select the nforce controller and your adapters wireless network connection ->right click on either and select Bridge This will create a networkbridge with both adapters. Instantly your internet should start working again. Note that the nforce controller is still disabled, so although using a bridge you are still only using the wireless connection, but the dns problem should now have disappeared. hope this helps!

Hej all, I had this problem also. I was connected through a router (wired). The solution to it was to disable all the drivers (uninstall them) then let the OS to detect and re-install it again. It worked for me, I hope it works for u too. Control Panel -> System -> device Manager -> then uninstall all Network adapters. Good luck :)

If upgrading Vista to Windows 7 - This was required on mine to get the wireless to work again. Start the Command Prompt "as Administrator" - in start menu left click the Command icon and choose option run as administrator In the Command Prompt window type netsh int ip reset c:\resetlog.txt ipconfig /release ipconfig /renew Once I did this, the solution above worked. The Windows 7 troubleshooter is worthless. Everyone loves seeing "use the internet to find a solution" for no internet connection. It just shows how little software is tested now days. This is why the Cloud may be doomed before it starts!Rx

I upgraded my Windows 7 i5 security to Norton 360 Premiums. This required an uninstall of Norton 360 and a complete new install or the premium version. I had to delete the previous app using control panel. After a week I received the DNS Server Not Responding Error. I followed the instructions about inserting preferred DNS numbers above and only got a limited connection. I ran Norton Update and this program accessed the internet and completed its process (no errors, limited connection) Next I Followed the instructions in another post, that suggested Disabling and Re-enabling your Network Adapter (Broadcom - Resets your adapter). This worked and my settings seem to be working better. I removed the preferred DNS numbers. Thank you

You may want to run a disk clean up or defrag. Windows has the program already installed.

This problem arises due to many reasons but you have to test all the cases. 1. Specifying a Public DNS is a good solution but it does not solve the issue with the internal DNS server. Why do we need to add a DNS to preferred DNS? This is the firs DNS server that the connection uses. You can add the other DNS server to alternate DNS servers. By adding alternate DNS server does the second DNS server also work with the connection? NO. The second one works if and only if the first (Preferred) DNS server is not functioning. So you have to add both and either one will work. Type: nslookup to a command prompt (cmd) to find the DNS server you are using. To verify that it is a DNS issue Ping a public IP Address. Type: Ping 209.85.175.106 and hit enter. This is a Google server IP address. If you receive a reply, you are experiencing a DNS issue. You have to test few websites using more than 1 browser (sometimes browsers also experience issues. Clear the temp files, cookies and cache to fix the issue). 2. In a command prompt: Type: ipconfig /flushdns and hit enter. Then type ipconfig /registerdns and hit enter. This will re-initiate the DNS connection. 3. To resolve any problems with ip addresses (DHCP), type ipconfig /release and hit enter. Then type ipconfig /renew and hit enter. Important! Type services.msc in the search area (start menu) and hit enter. Verify that the DNS CLIENT service is running. NSLOOKUP (Advanced): http://support.microsoft.com/kb/200525 4. Your firewall/internet security suite may be blocking DNS port 53. Try disabling the firewall or configure a port rule (port 53). The configuration varies and depend on your firewall type. This also applies to routers. If you are using a modem connected to the router, you have to configure ports for the client in some cases. Turn off MAC Filtering as well (or configure and allow the client PC). 5. In Device Manager, Click View > Show Hidden Devices > Network Adapters > Disable Virtual WiFi Miniport Adapters if enabled (Virtual). 6. If there are any other Virtual Adapters (VmWare etc if you are using), disable them. This will be further explained below. 7. Reset the Firewall to default settings. 8. Disable all network adapters and then re enable. Disable IPv6 settings. 9. If nothing works, open the Event Viewer (search) and then go to Windows Logs > System. Check for DNS errors. If you have changed the hosts file, you have to check whether there are specific settings in the hosts file. C:\Windows\System32\drivers\etc\hosts. 10. If you are using a VPN (connected) your internet connection is set to use VPN. Your company may block internet access to VPN most probably. Steps: Bring up the properties for the VPN Connection. Click on Internet Protocol Version 4 (TCP/IPv4) and then select Properties. Click on the Advanced button, then un-tick Use default gateway on remote network > Click OK. VMWare: If you have installed VMWare products, it will configure 2 VMWare Virtual Adapters. Never configure NAT with the same LAN IP. If you do, there will be many issues. If you have configured, change it with VMWare Virtual Network Editor. Edit > Virtual Network Editor. Or disable WMWare Virtual Adapter 8. 11. Reset the Adapter. Resetting: Launch cmd.exe as Administrator Firewall: netsh advfirewall reset Branch cache: netsh branchcache reset Winsock Reset: netsh winsock reset Note: All Winsock Layered Service Providers which were previously installed must be reinstalled. This command does not affect Winsock Name Space Provider entries. 11. Uninstall and Re install Network Adapter (LAN) drivers. 12. Change router port or router/switch. 13. Change DNS server (Internal). 14. Try a system restore. 15. Reset router and test. 16. Troubleshoot hardware issues. Hope this helps. This post is targets all the users who experience DNS issues.

Just had this same problem. Installed Win7 Pro 64-Bit on December 16th. Hasn't activated yet (our admin is still sorting out the KMS server). Yesterday afternoon, my home wireless connection lost access to the Internet. Access to the LAN is fine. Finally determined that it's not resolving DNS. Funny thing is, even NSLookup wouldn't resolve anything, yet, the DNS servers were fine. Kept noticing two wireless connectoids in my network settings. "Wireless Network Connection" is my normal wireless connectoid and was connecting fine. The second was "Microsoft Virtual WiFi Miniport Adapter" and was showing disconnected (as I expected). But, I couldn't figure out where that second connectoid came from, so finally, I disabled it. As soon as I did, my DNS sprang to life! I'm not sure if the OS is trying to activate, and interferring, or if that connectoid appeared as part of a Windows update, but disabling it fixed it for me instantly. Man, you are awesome Thanks Alot

Hi, Got up and running again after changing DNS server to 208.67.220.220. Network is based on a router and as it is now working, I have not tried the bypass action. Thanks, Tinky2
