Windows 11 and 127.0.0.1 DNS

  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

So I likely was having this problem before reinstalling but stopped to think about this odd problem I was seeing on a new install that I found and fixed that might be interesting for others.

So I run a BIND on windows 11 which is a shame they dropped support for windows but any how it worked and that my DNS server. Next I have my main PC windows 11 thats just been reinstalled and its setup has a lot of interfaces VLAN and DNS so

one interface is the main internet with DHCP DNS set to 127.0.0.1 no reply
another interface untag have DNS 192.168.255.49 that works with 192.168.255.60 as no reply until fail over by my routers.
Another interface VLAN53 with DNS 192.168.53.14 that works with 192.168.53.26 and 192.168.53.17 as no reply until fail over by my routers.

The problem
So everything works but every now and then after many sites the browser Edge or Chrome would pause loading a site for over about 5 seconds now some sites do take time to load but this was happening to simple or good fast sites. I tried many things and could not understand the problem I tried a reg setting NetFailureCacheTime to 0 but still it happened. Then looked at Wireshark loopback and see many requests to 127.0.0.1 which OK sure because I set that really it should use 192.168.255.49 and 192.168.53.14 when 127.0.0.1 fails which it does....

So I installed BIND simple setup for 127.0.0.1 to forward only to 192.168.255.49 and the problem went away!
