Windows 10 home - IP layer network issues after updating to 2004.

[DanTP]

After updating to windows version 2004, I suffer a really perplexing network issue:


+IP configuration is normal (and identical as before update to 2004).

+Ping to any IP (gateway and internet IP's) works fine

-No TCP/UDP seems to work for any windows app (including browsers, steam, etc.)

-nslookup produces no console output at all, and windows event log reports an APPCRASH every time it is run

+Everything *does* work fine in windows subsystem for linux (in the Ubuntu App I can use nslookup and it works, and I can download files from internet using wget over http etc.)


I did all the usual things like the network diagnostics and updating system, updating drivers, everything is up to date.


The only way to fix the issue was to rollback windows version.

I am running windows 10 home 1909 (19363.1198), which upgraded to 2004.


The only strange thing I noticed was some sort of network/security DOM errors in windows event viewer.
