Guest XaserIII Posted February 18, 2014 Share Posted February 18, 2014 Hi there,I'm facing some... weird.. issues with DNS requests. I don't know exactly when it started but it has gone real bad in the past few days. Basically every 2-3 link I click / site I load in Firefox 27 leads to a "Server not found" error, forcing me to manually reload the site (one or a few times) until the site is loaded properly.First I thought that the issue was entirely FF related and I consulted a few similar issue threads accross the web, deactivated DNS prefechting and flushed my DNS. However I now noticed that other programs have issues as well (e.g. the Secure Download Manager, self written C# WebClient applications, Visual Studio update etc.).Does anybody have an idea where this issue might come from?I also tried determining the current DNS server I'm using using ipconfig but that just shows the IP of my U.S. Robotics Router and I couldn't find anything in the router settings either.Thanks in advance,Max Link to comment Share on other sites More sharing options...
Tripredacus Posted February 18, 2014 Share Posted February 18, 2014 At a point where you cannot access a DNS name, go to the CMD and use NSLOOKUP to see if you can resolve the IP address. Link to comment Share on other sites More sharing options...
submix8c Posted February 18, 2014 Share Posted February 18, 2014 (edited) Don't know if this handy tool would help *anyone* but check it out.http://lifehacker.com/5420931/namebench-helps-you-find-the-fastest-dns-server-for-your-computerDisclaimer - I have *not* downloaded and tried (yet).FYI - I've had that on occasion as well. Having a router does the same thing (ipconfig) for me. The Router has a DNS IP as well.edit - HAH!

Guest XaserIII Posted February 18, 2014 Share Posted February 18, 2014 Hi,just to see if it fixes the issue, I changed my DNS server from my local ISP DNS to googles public DNS and until now, I didn't have any issues. I might call my ISP tomorrow and ask them to fix the issue. If I get issues with the google DNS server I'll report back, but thanks for the links.

Soukyuu Posted February 19, 2014 Share Posted February 19, 2014 Contacting the ISP is probably best, if your DNS is set to router IP, then you're probably using your ISP's DNS. The router is simply passing your requests to it. Link to comment Share on other sites More sharing options...
