Windows 11 DNS Over TLS "This system does not support required TLS version(s)"

  • DNS Benchmark v2 Release 5 with Consultant License
    Guest:
    If you own any earlier release of our DNS Benchmark you may immediately download its release #5 replacement. Running an earlier release will detect the new release and help you upgrade.

    Although this release is cosmetic, appearance matters and affects ease of use. The biggest change, as seen in the image above, is that the DNS Benchmark now has a traditional Windows application menu to more fully expose its many features. This release is also "Consultant License Aware" and GRC will now issue a Consultant version when owners have previously purchased four "Personal Use" licenses. If you have previously purchased four DNSB licenses, or if you wish to upgrade your "Personal Use" license to Consultant, GRC's purchase process will direct you through that process.

  • 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.

    (You may permanently close this reminder with the 'X' in the upper right.)

Let's explore:

DON'T BE FOOLED BY THAT "IIS", the tool interfaces directly to​
"schannel" (if you know what it is); use it to check/enable TLS 1.3​
and/or to ensure your SSL/TLS settings are ok​

IIS Crypto requires a minimum of Windows Server 2012 and the
.Net 4.6.2 framework or greater. Both GUI and command line
versions are available.
​
IIS Crypto GUI Version 4.0 (1.09 MB)​
​
IIS Crypto CLI Version 4.0 (1.03 MB)​
For older versions that run on Windows Server 2008 see here. ​

The [ Best Practices ] button results in the above image.

OK, give it a try, and reboot?!?
