Hey everyone,
I've had the same problem with Windows vista on a dell Latitude D830 using a wireless router. The weird thing is this problem is intermittent..one day I'll have internet, the next I won't. Then when I try to diagnose the error I get "Windows confirmed a Primary DNS server error", and also the "DNS server is online but not responding". I have another older computer that can still access the internet fine via the router. I can also pick up my laptop and go find wireless elsewhere like in a cafe and not have a problem. Can anyone help me out with this?
Thanks

Even though it appears you're having the same problem, please start a new thread when you have a new issue. It's very difficult to keep two problems straight and who's working on what in a single thread.

I've created a new thread for your issue here.

Note: You will need to post complete details of your configuration and your specific issue in this new thread for us to help you.

Thanks for your cooperation.

Recently I've had an issue with connecting to the internet. This problem is intermittent and and I can't figure out what seems to trigger it. One day I'll be able to connect to the wireless internet with no problem, then the next day I can't. However, I know the router is functioning because another older computer can still access the internet fine. In addition, if I take my laptop elsewhere (to school, to a cafe w/ wireless), I have no problem getting internet. When this problem occurs windows diagnoses a "DNS server error", and I get a message that says "DNS server is online but not responding". According to windows all the firewalls are properly set as well. When I go to the Command Prompt and type ipconfig, I get the following: (however, the internet is currently functioning as I copied this):

I'd like to see an IPCONFIG /ALL display when the error occurs.

Today I had internet fine, then put my computer to sleep (snooze, not shut down), and then when i powered it up again, I was without internet, and I got the same DNS error. So I did the ipconfig /all command, and the output is below. Later on tonight I suddnely have internet after shutting the computer down for 2 hours while i was out. I'm wondering if this could be something like the DNS server timing out? Or does the fact that I'm shutting down the hard drive periodically have something to do with it? Anyways, here's the output:

If this was connected to the same wireless network as you were previously, the gateway addresses have totally changed, which seems more than a little odd. This appears to be connected to a totally different wireless network!

Working connection: Default Gateway . . . . . . . . . : 10.71.1.1

Failing connection: Default Gateway . . . . . . . . . : 10.0.1.1

It appears from what I see that you are randomly connecting to a neighboring wireless network, which may explain why it doesn't work.

You seem to have been connected to two different routers (10.71.1.1 and 10.0.1.1)????

I dont' know how that could be though. Yes, the computer picks up several wireless networks, but most of them are secure. And the default one that it picks up is my wireless network, which it clearly says its connected to with a 'excellent signal' even when i cannot actually get online. Is there anything else I shoudl be doing to help with diagnosing this problem? Thanks for your replies though!

Please show an ipconfig /all for the 10.71.1.1 connection. Is that your router's address?

here is an ipconfig /all when the internet is working (after the rest of my writing) ...honestly I don't know enough about this stuff to tell you if 10.71.1.1 is my router's address. But this is what the network properties are which i accessed through the control panel:

What is interesting is someone else on this forum is having the same issues. His latest post mentioned that when he has internet, the little internet logo on the bottom toolbar on desktop indicates "local and internet' access. But when its not working, he, and I , get the same "local only" message. His thread is here: http://forums.techguy.org/networking/746897-vista-cannot-communicate-primary-dns.html

While what John said remains the primary suspect you could get those same results by having multiple Dhcp servers on your network. What is the brand and model of each of your modems, routers, switches, etc., and how are they and your computers all interconnected?

Also what you could do is temporarily disable your wireless connection and hard wire your computer to your router if possible. Then do an ipconfig /all and the default gateway will be the address of YOUR router, but make sure your wireless is turned off or disabled to verify.

I'm gonna go with JohnWill and assume you are connecting to a neighbor's wireless probably an airport or one specially configured.
