Hi All,

I have Windows XP and Windows 7 in a dual booting configuration.

I had internet in Windows 7 as perfectly as in XP. All of a sudden yesterday when I rebooted to Windows 7, it was not connecting to the internet anymore. Once rebooted to XP, Windows XP has internet as usual.

It is an Intel PRO/1000 CT Network PCI Adapter that comes with the Intel D875PBZ.

I have tried the following:

Uninstalling existing Network adaptor and let it reinstall

Installing and older driver

Turning on/off router (probably wasn't necessary as XP has internet just fine)

Trying to manually assign IP address

Once I had manually assigned IP addresses, the situation looked a bit improved. Earlier I couldn't ping anything at all.

But now:

192.168.1.254 is my router.

I am not sure what's going on. Something big is happening behind the scenes.

Any ideas would be much appreciated. :)

Thanks,

Did you look to see if your Windows Firewall is up?

It most likely is. Even if you are running another firewall program in Windows 7 make sure you have Windows Firewall turned off.

You have AVG on? - Try disabling that for the moment. On your TCP/IP connection you might find an IP filter along with the TCP/IP and other settings. Disable that as well.

You might go into local area connection properties and uncheck everything but Version 4 (tcp/ipv4)

I also had this problem but fix it this way. I set it to autotuninglevel=highlyrestricted

http://support.microsoft.com/kb/929868

But I also made my own DNS file.

http://www.mvps.org/winhelp2002/hosts.htm

Check my link below do this first.

I would do this first before any other changes.

Click All Programs

Click Accessories

RIGHT-click on Command Prompt

Select Run As Administrator

In the command window type the following and then hit enter: ipconfig /flushdns

Hey All,

Thanks for all the suggestions so far. I have tried:

System Restore: unfortunately it was turned off by Default!

autotuninglevel=highlyrestricted

uncheck everything but Version 4 (tcp/ipv4)

ipconfig /flushdns

I then went back to the default configuration: Obtain IP Address automatically

Autoconfiguration IPv4 Address. . : 169.254.91.21

That's some random IP address that I have no idea where it came from. My router's IP address is 192.168.1.254 which detects and works perfectly in other machines.

I am just going to hope a new build of Windows 7 will fix this. :)

Give this a try.

For Windows Vista, things work a little different due to introduction of UAC (Guide: Disable UAC). Use this guide to perform a reinstalling of TCP/IP protocol in Vista:

1.Click on Start button.

2.Type Cmd in the Start Search text box.

3.Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator. Allow elevation request.

4.Type netsh int ip reset in the Command Prompt shell, and then press the Enter key.

5.Restart the computer.

Are you log in as Administrator?

Oh my god. charles48864, that did it! :D

You are a champ mate.

Step 6 would be: Enable the Network adapter in Device Manager if it is disabled after the reboot.

This time I ran using Administrator account.

After that, everything is back to perfection!

Thanks again.

I have same problem as the OP of this thread. I have to confirm if Windows 7 was responsible for this issue :( I just thought it was some fault in my ISP or router.

Actually I have windows XP & before windows 7 Vista was perfectly working fine. But none of the windows 7 build had worked. I have the exact same issue as the OP. I tried everything that is mentioned in this thread but with no success.

Same problem. I have the RC build Win7 and thought it was my router or service provider. Booted into XP and works like a charm. Will try some of the suggestions above.

The netsh int ip reset command did nothing for me, but changing the DNS server to OpenDNS in my router seems to have worked. Havent seen a network error page for a few hours now. :)

Hey, all. Just wanted to throw in my two cents because I just searched every forum on google for my issue and couldn't find it. Here it was:

Ruing on Vista, specifically configured IP, DNS and other such settings to match with router and worked great :D Happy me.

Installed Windows 7 - Cannot connect to internet :( no es bueno.

Pinging and surfing by IP worked fine but no amount of changing DNS servers would help.

Tried every solution on forums, no dice. Found something by accident.

I actually went into control panel, security, and turned ON windows firewall's recommended settings. Worked like a charm. Happy again.

Hope that helps

hi everyone,

i had the same problem with W7 up until now (at least i hope it's cured...) - xp on the same hardware (and also another xp computer in the lan) would resolve names just fine but w7 would only at times and report "dns server is not responding" during 'troubleshoot problems'.

i tried everything from disabling/enabling the windows firewall, manually assigning dns servers (tried openDNS and my ISP DNS servers) and ip adresses rather than getting them via dhcp, various netsh things (reinstall ip, disable auto tuning), disabling everything but IPv4 for my lan connection... nothing helped.

in a last feeble attempt (i still have no idea why this makes a difference...) i changed my lan ip range back to 192.168.0.x from 192.168.13.x (had changed it some time ago for some reason) and now it's working... same /24 subnet mask, no other changes... gateway is now 192.168.0.1 instead of 192.168.13.1 and i haven't had any problems in the last 30 minutes or so while it wouldn't work without problems for more than a minute before... makes no sense to me but for whatever reason it seems to be working now...

"Pinging and surfing by IP worked fine but no amount of changing DNS servers would help."

for thinking its a dns issue - not one nslookup to see if you can actually query? If you think its an dns related problem -- show us the results of a dns query, setup debug, etc.

the trace router shows that your were doing dns lookups, since some of the hops returned fqdn.

First step of troubleshooting connectivity, if you have 169.254 IP -- then you did not get an IP from your dhcp server, this is microsoft's APIPA -- windows in infinite wisdom, if set for dhcp and don't get one -- then make up a random one.. :rolleyes:

With that IP no your not going to be able to do anything - but talk to other APIPA machines on the same local network.

If you can not get a dhcp IP, your going to have issues. If you go to setup a static IP, you need to remember to setup your dns as well.

"and turned ON windows firewall's recommended settings" I would not consider correctly configuring your software firewall to allow you do do what you want an accident ;)

Do you by any chance use Free AVG Antivirus?

I've installed the same Dell Hybrid 140G twise with win7 32 and 64 bit. At first it just runs smoothly, but after adding the features I normally add, I get the problem that the internet acces is interrupted by DNS reply errors.

I've now taken another 140G from stock and just installed Win 7 without AVG and that has NO problems??

1.Click on Start button.

4.Type netsh int ip reset in the Command Prompt shell, and then press the Enter key.

5.Restart the computer.

I just migrated from Windows XP to Windows 7 Professional X64 and I'm evaluating many anti-malware solutions for this platform. I already encountered twice losing my internet connectivity after removing anti-malware and restored to a backup. This time I wanted to discover a less time consuming solution.

I never had any issues with Windows XP, but remembered resetting winsock in similar circumstances I'm now experiencing with Windows 7. I followed the procedure above, but in step 4 I issues the command netsh winsock reset instead of netsh int ip reset. This time it worked.

Hopefully this helps someone else who stumbles across this topic with the same problem.

I also have DNS issues in Windows 7.

The problem is, I'm never able to do an nslookup because it only happens randomly--maybe a few times a day. I'll be browsing as usual, and the page won't load because of a DNS issue. If I refresh the page, it works fine.

It happens in Firefox, Chrome, Opera, and I've used OpenDNS, Google's DNS servers, and my ISP's servers. It happens on all of them :(
