DNS server issues in WSL Ubuntu Distribution on old Windows version

[claes-arvidson]

In our application we install an Ubuntu distribution running in WSL and some users running the applications had intermittent issues to connect to the DNS-server. This resulted in regular ping commands stopping to respond after a few minutes (or hours) unexpectedly.
Regular commands such as "ping google.com" did not work, whereas "ping 8.8.8.8" did.

After some days of investigation and reproducing by trying out wsl-vpnkit which made it temporarily work again, we tested to run Windows Updater to the latest installations in combination with lifting wsl2 installation from 2.4.10 to 2.5.7.
However, the solution here was to run the WSL updater which then made us never loose connection to the DNS server.

Without having investigated which package that solved this issue, then these were those that were upgraded:

Just as an FYI.
