DNS not working

[fml2002]

I'm having a problem connecting my 2 laptops (Acer Aspire with Win7 Home, HP Pavillion with WinXP Prof) to the internet. Spent 90 minutes on the phone with RoadRunner and they concluded that because everything appeared to be working fine with the modem, the problem must be on my end (even though the problem started at the same time for both laptops) and I'll be charged for the service call.

It looks like the internet is working fine - RoadRunner's tests say I'm connected and when I tried pinging the DNS values for Google.com and Yahoo.com, everything works but I get error messages when I try the actual domain name. This happens both with and without the firewall and when Avira is not running. Tried flushing the DNS cache numerous times, using OpenDNS, and wiping the browser cache but still no internet. I've also tried this wired and wireless (ASUS WL-520GU). I'm going to try the GoogleDNS when I have a chance but don't have much hope for that.

Because I'm having the problem with both computers, I can't believe that two laptops magically crapped out at the same time, but also don't want to pay for the service call. Any ideas on what might be wrong or what else I can try?

Thanks!

Can you ping 74.125.19.99? If you put that address in your web browser do you go to google? If so then you do have a DNS problem. If not you have another issue.

Yes, may not have explained that properly in my original post. Typing in the numeric address works, typing in the 'human' domain name does not. One of the RR service reps I spoke with had me try to ping both Google.com and Yahoo.com, and I was able to reach both home pages, but when trying the regular domain name, I received an error that the request had timed out.

Also, I have this same problem whether I use the 'automatically detect DNS' setting or use the OpenDNS. Haven't had a chance to try GoogleDNS or any of the others.

OK, I just wanted to make sure it is a DNS issue. The above in RED I don't understand. What do you mean by regular domain name. google.com and yahoo.com are regular domain names???

Would you post your ipconfig /all from at least 2 machines? -WS

This does sound like a DNS issue. The fact that 2 laptops fail to connect correctly would seem to eliminate a hardware issue with themselves. If using a router, have you tried setting the DNS addresses there?

Sorry, I would say that I have a better than average understanding of basic computing, but of this, I understand very little. I only meant that when I did as you suggested, ping 74.125.19.99, the Google homepage loaded with no problem, but when I actually typed 'google.com' into the address bar, that's when I receive an error message.

I won't be able to get home to post that info until sometime tonight (there's a McDonalds nearby, hopefully they have WIFI). Please let me know if there's any other info that might help.

Thanks!

But if the problem is with settings on the router, then shouldn't I be able to access the internet when connected directly to the modem?

Try these addresses: BBC - Homepage and 212.58.246.92. They should both take you to the BBC home page. If you can only get through using the numerical IP address, then it points to a DNS problem somewhere along the line. Once at the BBC site, can you navigate there by following the links?

Try this both through your router and then connected directly to your modem bypassing the router. Do you get the same results whichever method is used?

Now try these addresses: BBC - Homepage and 212.58.246.92. They should both take you to the BBC home page. If you can only get through using the numerical IP address, then it points to a DNS problem somewhere along the line. Once at the BBC site, can you navigate there by following the links?

I can try that one as well when I get home this evening but as I understand things, seems like that would have the same result as 74.125.19.99 getting me to Google's homepage but typing 'google.com' doing nothing. I'll let you know if it works.

Thanks.

I believe that Avira is causing this DNS problem. The post below explains the problem with Avira.

I was able to run a scan using Avira yesterday with no problem, but could it be that since I had Avira first, then tried using OpenDNS, Avira more or less killed the OpenDNS? Can't remember what the AVS is on the HP laptop but I don't think it's Avira and I'd been so frustrated that things didn't work with the Acer, didn't bother with the HP!

Thanks for the suggestion - saved it to a jumpdrive so I'll try that as well. If nothing else, it may give me a better idea of what's wrong.

 

[fml2002]

I've tried a few of the suggestions and so far nothing seems to be working. Tried using the OpenDNS on HP Pavillion and it didn't work. Also tried the DNS Jumper using multiple DNS services and each one came back "host is offline". Tried with Broadcom NetLink & wireless netork adapter.

Last night I brought my laptop home from my office (another HP Pavillion w/ XP Professional) and I'm having the same problem with it. Called RoadRunner and finally got them to agree if I'm having the problem with 3 computers, the problem is on their end and they're sending somebody tomorrow (Sunday) between 8am and 9pm.

Pasted below is the 'ipconfig /all' for my Acer Aspire. I got this while connected to McDonald's WiFi so I'm not sure if that would influence the report. If anybody has any ideas what could be wrong, please let me know

Thanks!

If you look at the parts in RED this is what you are missing or is not configured correctly.

Edit: I see the DNS addresses in there missed them the frist time. But the DNS suffix should be blank.

 

[brianzion]

forgive me if i have not read the posts properly but what router/modem are you using and who is your service provider?

 

[chev65]

Windowstar, the reason the DNS shows as mcd01541.det.wayport.net is because he is connected to micky D's wireless connection where they use a restricted DNS server. I'm also pretty sure that the Op has also tried using manual DNS entries.

The only other DNS problems I could find were in this Technet thread which showed a few fixes for the problem which usually resulted from upgrade installs, VPN software, Msoft mini port problems which can be fixed by disabling the miniport, or a few other possible problems "click the link below".

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.

Windows 7 DNS server not responding

 

[WindowsStar]

chev65, understood, however I have seen DNS suffixes like "mcd01541.det.wayport.net" mess up DNS because when you type in www.google.com in your web browser, it gets resoved as "www.google.com.mcd01541.det.wayport.net" which does not exist, so IP addresses work but names never resolve correctly. This may not be the case here, but removing it would be a good test. -WS

I havn't seen one like that either to be honest although that ipconfig was from a working connection at McDonalds so I think it's just some lame restricted DNS they make you use.

I posted all the DNS fixes I found for Windows 7 from the Technet sites which showed a few ways to fix this sort of problem.

Well we will wait for the OP to post back, maybe some light will be shed on this.

Last night I brought my laptop home from my office (another HP Pavillion w/ XP Professional) and I'm having the same problem with it. Called RoadRunner and finally got them to agree if I'm having the problem with 3 computers, the problem is on their end and they're sending somebody tomorrow (Sunday) between 8am and 9pm.

Did anyone turn up, and if so, what did they say?
