    DNS resolution lag across entire machine, other PCs on network fine?


    I have an issue that I have never seen before. The core problem is that often, when I go to websites, Chrome seems to be stuck on “resolving host” for 4 to 10 seconds, and eventually brings the website up. The same DNS lookup lag happens in Firefox, Edge, and IE as well.

    I have tried connecting via both wired and wireless, and get the same issue either way.

    I have tried disabling IPv6, no help. I also tried with both the ISP-provided DNS serves and Google DNS servers (8.8.8.8/8.8.4.4), same trouble either way.

    We have another PC on the same network, also wired, that has NO trouble with DNS, websites come up very fast. We've even swapped the router plug spots, to no avail.

    On the problem PC I’ve even gone to a command prompt and typed in “nslookup”, and sometimes I get timeouts right away. Sometimes nslookup says:

    Default Server: Unknown
    Address: 24.223.0.16

    And sometimes it says:

    Default Server: sulfur.intertech.net
    Address: 24.223.0.16

    Either way, when I type in a domain like yahoo.com at the prompt, I often get:

    DNS request times out
    Timeout was 2 seconds
    DNS request times out
    Timeout was 2 seconds
    DNS request times out
    Timeout was 2 seconds
    DNS request times out
    Timeout was 2 seconds

    …for a bit. On the other hand, sometimes I don’t get any timeouts and the nslookup just resolves the way it’s supposed to.

    My security/firewall is the basic Windows Defender built in one. This computer is a brand new windows 10 desktop.

    Whatever do I do now? Having most webpages take 5-10 seconds before the DNS resolves and the page loads is driving us nuts! Why is DNS so compromised on this PC, regardless of DNS server specified, regardless of which network adapter (wired or wireless) I use? What’s my next step??

    Thanks.

    :)

  2. Windows 10 DNS caching problem

    After some time of messing around with the two windows 10 machines I have, one a laptop, the other a surface pro 4, I've consistently hit the DNS resolution issues that many other people have reported.

    Basically what happens is DNS resolution stops functioning for a period of time, however previously cached domains still resolve. A simple and effective solution to this is to just flush dns cache with ipconfig /flushdns command. More frustrating is that
    it appears when DNS resolution fails, nxdomain is cached as well (which may actually be a significant part of the problem).

    Microsoft network engineering should take a good look at how the resolver cache is handled, as it appears that some failure which results in DNS resolution failure will end up with a cached nxdomain (which should never happen). The fact that a simple dns
    flush fixes the problem instantly strongly suggests that there is a bug in this part of the code which needs closer examination.

    "They said that DNS should not be 192.168.0.1"

    OK, so the DNS setting on your network connection should be pointing to whatever is managing your DNS resolution. This is commonly either a server on the network in an office or can be as simple
    as the router serving the network. If it's the router that you need to point to then this IP address may well be correct - this does sound like the sort of IP address a router would have so it sounds a little like jumping to conclusions.

    If we assume that this is a DNS problem, and if its the DNS resolution from the router that's faulty (lots of IF's here!) then something you can try is pointing to an external DNS server. An easy
    one to use is google, so in the network adaptor settings change the DNS you mention above to 8.8.8.8

    DNS resolution lag across entire machine, other PCs on network fine?

    Google Chrome does have a known issue when trying to go to websites on Windows 10. It is a known bug that Google has to fix. Firefox works fine, do not know about Opera, since I have not tried it on 10.

    If it has been happening with all browsers on your computer. Have you tried updating to the newest driver for the network device?
