Windows 7 RC - Web Browsing Issue
Almost everytime I try to load a webpage, it fails. Showing the "Try Again" message in the browser. This happens with Internet Explorer 8, Firefox 3.1, Opera 9.1, ETC. This is very frustrating, cause in Windows XP, I have *NO* problem at all. I've been looking for a solution for over two months, and this is the only reason why I always go back to good ol' Windows XP. Maybe 3 out of 10 tries, the webpage loads succesfully.. the other seven, it just won't load or load approx. 10% of its content until it stops, etc. When it fails and I hit "refresh" it loads! (Not everytime tho, but most of it). Kinda weird huh? I think this could be somekind of DNS problem, but with exactly the same configuration, I have NO problems under Windows XP. (I've done several clean installs of Windows 7 and no luck)

Is it a wireless network adaptor that you are using or are you wired?
June 22nd, 2009 1:04am

I am wired. I've connected this modem to my MacBook Pro, and I do *not* have this problem. in Windows XP, using the same modem and same settings, *no* problem also.

At first glance I thought that read, I am weird. lol Anyways, you're going straight from the modem into the desktop?
June 22nd, 2009 5:24am

hahaha. yeah, I've tried both: dsl modem straight to desktop. and: dsl modem to wireless router to pc. Both give the same browsing experience under Windows 7. Both ways work perfectly fine with Windows XP or MacBook Pro. This problem also happens with Windows Vista. I've had two different computers and they both give this problem when it comes to web browsing under Vista or Windows 7. Two completely different setups, different motherboards/ethernet cards and exactly the *same* problem. I am going nuts here

Hi, Can you log on your Live Messenger? If so, the root cause should not be the network. In this case, I suspect that your anti-virus or firewall block HTTP protocol. I suggest that you temporary disable or uninstall the security programs, and then check the result. However, if you could not log on Live Messenger either, there can be some network connection issues. I suggest that you upgrade the network adapter driver. If the issue persists, please let us know if you have wireless and wired connection. If yes, change the connection to another and check if the issue still occurs. If the above suggestions does not help, please let us know if it works in Safe Mode. Also please let us know if the Windows Vista computer and Windows 7 RC computer could access other computers in the local network.Arthur Xie - MSFT

I can log on into Live Messenger. I also do not have any problems downloading stuff. I seem to have a pretty stable connection. Problem is while Web Browsing. It behaves as if the connection were somekind of "intermitent". I have tried running Windows 7 with and without AV, with Firewall ON and OFF, same result. Right now I am wired; DSL Modem (SpeedStream 5660) straight to PC Ethernet (MSI 790FX-GD70 Motherboard onboard ethernet). Windows 7 RC Build 71000, Avast AV, Windows Firewall ON. I have also tried: DSL Modem > Linksys Wireless Router > PC (wired). Same result. I have also tried booting up in SafeMode (with Network) and still same "inestability" while browsing. Even tho its less noticeable under SafeMode. * I would like to point out that, if I go and install Windows XP right now, I don't have this problem at ALL without touching anything. Everytime I get the "Try Again" error from the browsers, Event viewer reports the error as follows: Level: Warning Date and Time: X Source: DNS Client EVents Event ID: 1014 Task Category: None Under General: Name resolution for the name ad.doubleclick.net timed out after none of the configured DNS servers responded.

@azynkron: " Does this happen when you stream and download files aswell? That you have problems getting the file? " - I do have problems, but not everytime. I can set a large download, and go perfectly fine (4GB lets say). Once the connection is "stable" it goes well. The problem is that, I have to try a couple of times before that connection becomes "stable". " Perhaps you need an updated driver for the NIC? What does MSI use on those boards? " - Acording to Windows 7's Device Manager, I have the Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC . Windows 7 downloaded the driver by itself (NDIS 6.20 ). I have tried to search for a newer driver online with no luck. I didn't install the one that came with my Mobo's DVD Driver because it just won't open. Maybe the included NIC driver installer is not compatable with Windows 7. @Adam M MCP: " You may have add-ons in your browser that need to be disabled." - I don't. All the browsers are at Default settings. (IE 8, Firefox, Opera, Chrome) @ Bubbapcguy: " Are you running any VPN software?" No. "Check that you are not connecting both wired and wireless at the same time (check bluetooth PAN as well if you use that)" Done, I am only wired. "Are you using any PHISHING blocking software?? browser based or otherwise?? As Adam stated disable any/ all browser add-ons" No. * I will run those commands now, and will post later with results. Thanks all for the help so far guys, I really appreciate it!

It's understandable that some plugins may have issues causing the browser to have issues loading. But, if you're running the same browser with the same plugins on Vista as you are on 7 and Vista works 100% of the time, shouldn't they be looking for a cause as to why 7 dumps the connection instead of looking for temporary fixes?
June 25th, 2009 4:39am

I tried to reset the winsock and restart but my connection is still "unstable". Same problems still occur. @jdsingle: I have the same problems under Vista too, but not under Windows XP. I do agree with you tho, We should try to find the reason why Vista/7 dumps the connection and XP does not. @testestest: Could you please post which motherboard you are using at the moment? which ethernet card?

Since the issue still occurs in Safe Mode with Networking, it may be not related to the Internet browser. I suspect that this is a DNS issue. You may try to access the website with its IP address. Please enter the following string into the address bar of IE. http://74.125.242.89/ If it accesses properly, it should be a DNS issue. In this case, please let us know if the computer is in domain, if other computers in the same network have the same issue, and if the computer is behind a Internet proxy.Arthur Xie - MSFT

Arthur Xie - MSFT The page loads fine (just text right?). I tried several times, all of them worked. This is the only computer in my network, some laptos come to play from time to time (WiFi). My current setup is as follows: DSL Modem/router > Linksys Wireless Router > PC. all connected with wires, so my PC is getting the net straight from wires, not wirelessly. DHCP Enabled on DSL modem. I have set the OpenDNS in my DSL router as default. (DNS numbers) (long time ago) So whatever is causing this *issue* is because of some "automatic" setting of Windows 7 or Vista. Anyways, what I find strange is, why do I get this experiencie *ONLY* in Vista/7? XP Works just fine, OS X 10.0 - 10.5 just fine, Linux Arch, Ubuntu just fine. Anyways, Thanks for your help. Looking foward to your tips sir.

Well since it is only happening on Windows 7 it is going to be a DNS setting on your Windows 7 machine. What do your web browsers show for their DNS settings? Maybe if you set it manually instead of automatic, pointing the browsers to the router directly, does that help?
June 27th, 2009 6:31pm

@Adam M MCP "What do your web browsers show for their DNS settings?" where can I see this? Anyways, I opened IE 8, under Tools > Internet Options > Connections > LAN Settings, I typed in 192.168.1.1 and saved. After 3minutes of browsing, bam, back to the same ol' errors. In Firefox, it only lets me add/configure a Proxy. just in case, here are my current settings: Configuration for interface "Local Area Connection" DHCP enabled: Yes IP Address: 192.168.1.100 Subnet Prefix: 192.168.1.0/24 (mask 255.255.255.0) Default Gateway: 192.168.1.1 Gateway Metric: 0 InterfaceMetric: 20 DNS servers configured through DHCP: 208.67.222.222 208.67.220.220 Register with which suffix: None WINS servers configured through DHCP: None

Have you tried to disable the features on your local area connection? I'm thinking that perhaps if you switch QoS, IPV6 support e t c off one by one, you can perhaps see if it's one of those services that causes it?

just in case, here are my current settings: Configuration for interface "Local Area Connection" DNS servers configured through DHCP: 208.67.222.222 208.67.220.220 Your setting shows that you are using opendns.org as your DNS provider and it looks like you are not able to connect to them at times. Try changing those to the default DNS used by your ISP.

I have two PC's in front of me. One with Windows 7, the other XP/Vista dual booting. The issue occurs at random, but never on XP. When I go to a webpage and it fails to load, the status bar indicates "Looking up <webpage>" then goes to the fail page. Then a few seconds later, my network connectivity indicatorshows that my connection has dropped. This happens when any amount of network traffic is going across whether it is just streaming music, torrent traffic, web browsing, gaming, etc. - changed DNS's several times pointing to different resources (OpenDNS and ISP-based) to no effect. - installed the latest nForce motherboard drivers that are available. - uninstalled networking adapter and rebooted and it did reinstall, but connectivity still drops.- connected directly to modem, same result- W7 is a fresh install- unchecked any power saving features on the network adapterEverything was working fine until about a week and a half ago.

The problematic computers may access Internet via proxy, or the ISPs they are using connect to Internet via proxy. It should not be a Windows 7 RC issue because on our test computers it works properly. After clean installation and before you test the issue, is any program installed, especially anti-virus, anti-spyware or firewall? If the issue occurs on a complete clean system, you may need to contact your ISP or proxy administrator to fix the issue.Arthur Xie - MSFT

I have had similar symptoms on my new build I7 920/ Win 7 RC system. Many, many failed page loads, mostly in IE8 but also in Chrome. My ISP and modem/router setups seem fine. Reading this thread started me thinking and I went anddisabled the Active Surf-Shield portion of the LinkScanner in AVG free 8.5. It has only been a few hours, but this seems to have solved the problem (fingers crossed). I did a quick check of the AVG forumsbut didn'tfind any reference to this specificproblem. If you use AVG you might want to give this a try.

I don't think its related to my ISP, cause on every other operative system it works just fine. (MicroSoft Windows XP included). Anyways, I went ahead and talked to them about it, and they told me that my settings were fine, that I shouldn't have any problems because of them (ISP). Any new ideas?

Yes, I have a SpeedStream 5660, privided by my ISP. This router is kinda old.. about 6 years I believe. I was thinking of the same thing the other day.. maybe this router has problems with Win7.. maybe Win7 requires more transfers or protocols (don't know, I don't know much about Networking) but could this be a problem? cause under other OS's this router works just fine. On the other hand.. I can't bypass it, since here in my country (don't know about others) is my only way of actually *getting* internet. I have DSL, so the telephone line goes into the router, then the router goes to my computer. Without the router, I have no way of getting internet. Should I try to get another router and see what happens? Thanks again man.

I actually had a similar problem and the other night I totally disabled the FW in Win7. I mean, I have a pretty solid one in the router.. soo.. Though it needs a bit more testing, I feel that browsing is more stable. Now, there should be a way of suppressing those security messages. I know what I'm doing and it's rather annoying to be reminded all the time.

Hello ITFreak,i also had the same problem due to many factors it can be Ddos attacks when you say you load it and it charges till 10% then stops that looks like typically socks problems ,look like syn flood and when you said it dont even open and then you showed us the management logs that happened to me 2 months ago and yes the problems were related to DNS servers then i changed to open dns and it works like a dream now,it could be ISP problem too but it souds more like dns configurations maybe when you configured your firewall connection rules you set to require authentication for dns server in Endpoint2 which makes it go like that...so hope this helps cause exactly the same "issue" happend to me!!RegardsRR

Folks: I'm having the exact same problem. I am running Windows 7 RC Ultimate x64 on one machine, and I often experience a spontaneous, system-wide loss of DNS service. === Symptoms === * DNS service is lost to all applications at the same moment. Network connectivity is not interrupted. * The outage arises spontaneously: no consistent set of actions occur before it arises. And this occurs (rough estimate here) about once every three hours. * At approximately the start of the outage period, a single Event Log entry is created, reading: "Name resolution for the name [THE NAME OF SOME SERVER I WAS TRYING TO ACCESS] timed out after none of the configured DNS servers responded." * DNS service spontaneously (i.e., without any intervention from me) resumes within approximately 10 to 60 seconds. (No event log entry is created when service resumes.) === Diagnostic information === * This is NOT caused by my ISP, router, wireless network, etc. I have two reasons for asserting this: (1) This occurs on my home network, where I am also operating three other machines (one Vista Ultimate x86 and two XP x86 SP3.) None of them have ever exhibited this behavior. Also, during the period of DNS outage on the W7 machine, the other three machines continue to have DNS access. (2) The W7 machine is a notebook, and the same issue happens when I'm connected at work on an entirely different network. * This is NOT a network adapter or connectivity issue. I have three reasons for asserting this: (1) My 802.11n network adapter continues to report full connectivity. (2) During the DNS outage, I still have network access: file transfers that have already been initiated continue through the outage period without any slowdown or interruption. (I'm running DU Meter and can watch the transfer rate closely.) (3) The W7 machine exhibits the same behavior when I'm connected to my home network using the 802.11n adapter as when I'm connected to my work network through a regular, wired NIC. * This is NOT a hardware issue. Before installing W7 about two months ago, I ran Vista Ultimate x64 on the same machine for a year, and this particular behavior never appeared on the Vista install. No hardware changes have occurred. * This is NOT an application-specific issue. DNS service is lost simultaneously, and is restored simultaneously, to all applications: Firefox, Thunderbird, iTunes, even attempts to update the security definitions in Kaspersky from a proxy server. === Conclusion === To me, it seems quite clear that the Windows 7 RC has a serious DNS bug that cripples internet access. I'm guessing that there is some sort of bug in the DNS client service. I'm guessing that there is some sort of resource miscoordination - maybe a race condition involving a semaphore or lock. And although the resolution on my machine is spontaneous, others are reporting permanent loss of service until a reboot... that suggests a hung process. Regards, David Stein

However, I do not agree with your final conclusion. In some cases, anti-virus may monitor the DNS client service. When the service is working, the program will consume lots of resource to check data. I suggest that you temporary disable or remove Kaspersky and confirm if the issue occurs. If it works well, you may try to configure Kaspersky to not monitor the behaviors of DNS Client service. If anyone has problems when access a website by name, the best way to determine if the issue is caused by your network environment is moving the computer to a different network. If the computer is a desktop, you may check if other clean Windows 7 systems have the same issue.Arthur Xie - MSFT

Check to see if the DNS Client Service is disabled. I believe this was causing similar problems for me, but I have not experienced any issues since setting the service to Automatic and starting it. I have not yet proved, but am guessing that Kaspersky disabled the service for some reason.

Hey MDowdie, It is enabled. This is happening straight from a fresh installation of Windows 7. I've installed Windows7 like 12 times by now, and still, It shows this kind of network problem. Very unstable connection. it affects Online games too, everything that HAS TO DO ANYTHING with Internet. It sucks BIG TIME.

Folks: I'm having the exact same problem. I am running Windows 7 RC Ultimate x64 on one machine, and I often experience a spontaneous, system-wide loss of DNS service. === Symptoms === * DNS service is lost to all applications at the same moment. Network connectivity is not interrupted. * The outage arises spontaneously: no consistent set of actions occur before it arises. And this occurs (rough estimate here) about once every three hours. * At approximately the start of the outage period, a single Event Log entry is created, reading: "Name resolution for the name [THE NAME OF SOME SERVER I WAS TRYING TO ACCESS] timed out after none of the configured DNS servers responded." * DNS service spontaneously (i.e., without any intervention from me) resumes within approximately 10 to 60 seconds. (No event log entry is created when service resumes.) === Diagnostic information === * This is NOT caused by my ISP, router, wireless network, etc. I have two reasons for asserting this: (1) This occurs on my home network, where I am also operating three other machines (one Vista Ultimate x86 and two XP x86 SP3.) None of them have ever exhibited this behavior. Also, during the period of DNS outage on the W7 machine, the other three machines continue to have DNS access. (2) The W7 machine is a notebook, and the same issue happens when I'm connected at work on an entirely different network. * This is NOT a network adapter or connectivity issue. I have three reasons for asserting this: (1) My 802.11n network adapter continues to report full connectivity. (2) During the DNS outage, I still have network access: file transfers that have already been initiated continue through the outage period without any slowdown or interruption. (I'm running DU Meter and can watch the transfer rate closely.) (3) The W7 machine exhibits the same behavior when I'm connected to my home network using the 802.11n adapter as when I'm connected to my work network through a regular, wired NIC. * This is NOT a hardware issue. Before installing W7 about two months ago, I ran Vista Ultimate x64 on the same machine for a year, and this particular behavior never appeared on the Vista install. No hardware changes have occurred. * This is NOT an application-specific issue. DNS service is lost simultaneously, and is restored simultaneously, to all applications: Firefox, Thunderbird, iTunes, even attempts to update the security definitions in Kaspersky from a proxy server. === Conclusion === To me, it seems quite clear that the Windows 7 RC has a serious DNS bug that cripples internet access. I'm guessing that there is some sort of bug in the DNS client service. I'm guessing that there is some sort of resource miscoordination - maybe a race condition involving a semaphore or lock. And although the resolution on my machine is spontaneous, others are reporting permanent loss of service until a reboot... that suggests a hung process. Regards, David Stein Hi David, I agree with your diagnostic information. However, I do not agree with your final conclusion. In some cases, anti-virus may monitor the DNS client service. When the service is working, the program will consume lots of resource to check data. I suggest that you temporary disable or remove Kaspersky and confirm if the issue occurs. If it works well, you may try to configure Kaspersky to not monitor the behaviors of DNS Client service. If anyone has problems when access a website by name, the best way to determine if the issue is caused by your network environment is moving the computer to a different network. If the computer is a desktop, you may check if other clean Windows 7 systems have the same issue. Arthur Xie - MSFT I'm having the exact same issue. But with: windows 7 RC (7100) 64 bits Avast antivirus Dell laptop w vista upgraded to win7 Please help, this is very intermittent and very annoying.

Seems like I'm having the same issue:http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/6fba5b08-f767-4d06-b0ae-9e87afeb1ddbCommon threads:- same Realtek NIC (suspicious), I've loaded the latest driver (posted Oct 23) but problem persists (although I run fine in Safe mode, so does this absolve the NIC driver?)- DSL modem also, but weird if this would be causing the problem - XP and Vista computers connected to the modem work fine (as does Win7 in save mode)- I've removed antivirus, turned off Windows firewall, run IE without add-ins (and problem is evident with any program accessing internet anyway, just trying everything).I'm stuck as well, ready to revert back to Vista, any thoughts out there?Doug

I had a similar problem, what fixed mine was disabling two services:- Function Discovery Resource Publication, and-Function Discovery Provider Hostand all is well again.I'm no expert at this and flying blind mostly, use at your own risk.Good luck,Doug
