Wysylanie zapytan DNS do wszystkich serwerow

[EyeOfIllu]

Zauwazylem, ze w wersji Win10 1909 i 21H2 wystepuje problem wysylania zapytan DNS do wszystkich dostepnych serwerow wpisanych w ustawieniach TCP/IP. Jest to nietypowe zjawisko, ktore zostalo takze zaobserwowane przez innych uzytkownikow systemu Windows 10 (https://learn.microsoft.com/en-us/answers/questions/622012/need-help-to-understand-when-windows-laptop-pc-sen)
Podobno to jest rozwiazanie:

Reg.exe add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\DNSClient" /v "DisableSmartNameResolution" /t REG_DWORD /d "1" /f
Reg.exe add "HKLM\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters" /v "DisableParallelAandAAAA" /t REG_DWORD /d "1" /f
