I know there are multiple threads on this issue, but it's difficult to sort through all the recommendations and configurations to find out what the appropriate fix is for the issue. My internet connection randomly drops during use and when I come back to the computer at random times. The only way I can get the Internet functioning again is by unplugging the power from the back of the cable modem and plugging it back in again. There has to be an easy fix for this issue, I can't believe Microsoft hasn't said anything about it. I've researched this error for the past two weeks and none of the fixes I've seen have been working. I am running Windows 7 Professional 32-bit and constantly receive the Event ID 1014 DNS Client Events error in the Event Viewer. I am connected through a cable modem (Scientific Atlanta DPC 2100 R2 Series Modem). *I have no anti-virus or third party software installed on my system *I have Windows firewall enabled. *The NIC drivers are all up to date *IPv6 is disabled *I am running Firefox 3.6.6 *All check boxes under the Power Management tab for the NIC properties are checked *All Power Options are set so that the system never sleeps or hibernates

Hi mitchkas When Harware is the issue, software can't do anything. When you unplug the cable modem and plug again, you're forcing a reconnection with your service provider. If the link fails, please make a support call to your provider. Maybe the cables, links, connections between your provider and you home have issues like intermitent connections, noise, water, whatever.

Happened again this morning ... I checked the Event Viewer, and sure enough, 2 more entries. I will try tech support for my ISP, but I just have a feeling that it's something to do with all this IPv6 stuff that Microsoft included in Windows 7. Also, this morning, I disabled the three IPv6 features on the Advanced tab for the LAN properties, hopefully that helps.

What I did was a little Internet research to figure out how to permanently disable IPv6. I had to make a quick adjustment to the registry in order to get that accomplished; we'll see if this works. http://www.tothepc.com/archives/disable-ipv6-on-windows-7-vista-pc/

still doesn't work after disabling all these services, I'm tired of this, I'm going back to XP

We'll see what happens... I've been working on trying to fix this issue for almost a month. I have done so much research and testing and tweaking to get it fixed and nothing seems to be working. I really don't think something this simple should involve this much work to get working properly.

Hi, Please obtain the following hotfix: You receive a stop error after you enable the RequireinClearout mode on an IPv6 network on Windows Server 2008 R2 or in Windows 7 BTW, I would like to recommend you to visit: You may experience connectivity issues or performance issues when you connect a mobile PC that is running Windows Vista or Windows 7 to a wireless access point Best Regards Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.

Before I try this hotfix, I want to see if the one change I made will work... I went into the Device Manager and clicked on "Show Hidden Devices" and disabled Microsoft 6to4 adapter, Microsoft ISATAP adapter, and WAN Miniport (IPv6). I restarted the computer after that and I'm waiting to see if that holds.

Well, the hotfix did not work and after the problem surfaced (in the middle of browsing the web, DNS decided to quit working). I ran the network connection diagnosis and the following two entries were made in the Event Viewer: Details about network adapter diagnosis: Network adapter Local Area Connection 2 driver information: Description . . . . . . . . . . : Realtek PCIe GBE Family Controller Manufacturer . . . . . . . . . : Realtek Provider . . . . . . . . . . . : Microsoft Version . . . . . . . . . . . : 7.2.1127.2008 Inf File Name . . . . . . . . . : C:\Windows\INF\netrtx32.inf Inf File Date . . . . . . . . . : Monday, July 13, 2009 8:46:34 PM Section Name . . . . . . . . . : RTL8168D.ndi Hardware ID . . . . . . . . . . : pci\ven_10ec&dev_8168&rev_03 Instance Status Flags . . . . . : 0x180200a Device Manager Status Code . . : 0 IfType . . . . . . . . . . . . : 6 Physical Media Type . . . . . . : 14 The Network Diagnostics Framework has completed the diagnosis phase of operation.

If reinitializing your cable modem (unplugging and replugging) fixes the issue every time, I suspect your cable modem is failing. Some things you might try to check this: Replace the cable modem (if it was supplied by your cable provider they'll probably do this at no charge) Put a router between your PC and the modem. The DNS will probably still fail, but if it's the modem the errors should be different as the computer can still contact the router's DNS service. Have a friend with a laptop drop by and hook it up to your connection. If it doesn't fail, then it's your computer/Windows 7; if it fails, it's the modem/connection to your ISP.

replaced my cable modem and the problem is still not fixed.still receiving these events in the event viewer during the time of slow/no internet access: when I tried accessing the Internet sites this morning, only about half the site actually loaded then quit Here are some of the events in the event viewer at the time of the stoppage: *The browser has forced an election on network \Device\NetBT_Tcpip_{162620B4-6288-40F9-8DF4-2922771F2FEB} because a master browser was stopped. *The TCP/IP NetBIOS Helper service was successfully sent a stop control.

Try this: Network Connectivity Status Indicator and Resulting Internet Communication in Windows 7 and Windows Server 2008 R2 http://technet.microsoft.com/en-us/library/ee126135(WS.10).aspx Same issue on my system. I tried this (EnableActiveProbing= 0) and got error free relief for several days. Surprising. But isn't this just masking the symptom not addressing the cause? In any case, today, the Network Service tried again to get to dns.msftncsi.com, and timed out. The reg setting is still zero. Very disappointing.

This doesn't appear to do anything on my system. I tried it both ways, with the registry edit and with the security policy change to turn off the feature. The NETWORK SERVICE still tries to contact dns.msftncsi.com.

Hi, Im having the same problem with Event ID: 1014 - DNS Client Events. Name resolution for the name "messenger.hotmail.com" timed out after none of the configured DNS servers responded. ("" be whatever webpage I visit) Resulting in unstable connection. Did u find a solution? Regards

I've been dealing with this for five years, since Windows Vista. I've decided this is an ISP issue. Last month my cable provider notified me they would be doing an upgrade of equipment on my street. This reduced the problem considerably, but did not eliminate it. If service hangs, check modem to see if you have data signal, which is definitely an ISP problem. Sometimes the signal is there and sometimes it is not. The 1014 error is only symptomatic of some other problem, you can lose connectivity and the record will not always be entered.

I have the same issue. But only on 1 computer, another is running fine and I have no networking issues with my xbox 360 as well. All 3 are connected to a fritzbox. So this is not an ISP issue or all devices will face this error.

Hello there, Well for past 2 weeks I was having the same problem as you have with Event ID 1014 keeps popping up and my internet connection going on and off while local LAN connectivity was still on. After browsing dozens of solutions and pages no one worked for me. So I tried to fix it on my own and I think I found a way to fix this problem in this particular scenario. If you are connected to you PC be it laptop or desktop through WiFi and get Event ID 1014 OR your router is N capable and your pc is only G ready then please read: Open your router admin page which should be 192.168.1.1 and enter your credentials. Then navigate to the page where you have advanced setting for your wifi or the page (browse to find) where you can change and alter these settings: Band: 2.4 (or what your country supports or dual mode) Channel: 11 (or what you country supports or dual mode, but do remember this and note down) Standard Mode / Mode: Select only G if you laptop of desktop is not N capable and avoid abg or bg or gn or abgn. And save these settings. Now go to you desktop/laptop Network and Sharing Center (Windows 7) and go to Change Adapter Settings, right click on your wifi adapter and go to Properties and on the pop up windows click on Configure, thne on next pop up windows click on Advance tab and here select same channel as you selected on you router for ex: 11 and mode/type/frequency as only G not abgn, bgn, or gn and save and exit. What you have done here is that your router and pc are now communicating on same channel and standard which is G and there is no guessing and discovering left for your PC so there will be no more connection lost or Event ID 1014. This worked in my scenerio with 99% success. Also do try Google Open DNS 8.8.8.8 and 8.8.4.4 in you router as static DNS setting for all your devices. Nothing hurts to try. Goodluck.
