Maybe someone has dealt with this recently. I would appreciate any suggestions 
The issue I am facing:
1 particular machine running Windows 10 has no internet. It shows "No internet" and really you can't go to any website. but ping to an outside server is responding
Details about my system:
Pretty straight forward
Windows 10 -> Pihole -> Router/Unbound/Firewall -> Cable modem
I have one machine that suddenly stopped contacting Pihole and has no internet .My suspicion is Windows 10 Updated to 2004.
The Update History shows 2004 updated about a month ago but the user said the machine was updated just today after a shutdown.
Something weird for sure,
if I run ```
ipconfig /displaydns
nothing shows
it will just freeze, it will also freeze when I change IP settings for the adapter, change DNS settings etc..
Originally I put P-hole IP as preferred DNS server, than I added 1.1.1.1, and I can;t remove them now.
ipconfig /all
Default Gateway . . . . . . . . . : 192.168.1.1
DHCP Server . . . . . . . . . . . : 192.168.1.1
DNS Servers . . . . . . . . . . . : 192.168.1.100 (Pihole)
1.1.1.1
NetBIOS over Tcpip. . . . . . . . : Enabled
shows 2 DNS servers, but I can't remove them
Pihole Log shows only queries that initiated with nslookup
but nothing from a browser or ping
nslookup pi-hole.net
doesnt resolve anything
ping 1.1.1.1
Pinging 1.1.1.1 with 32 bytes of data:
Reply from 1.1.1.1: bytes=32 time=112ms TTL=54
Reply from 1.1.1.1: bytes=32 time=18ms TTL=54

One more thing
The firewall log is showing many many UDP entries from this machine to 8.8.8.8 and 8.8.4.4 on port 53
09:11:23 FORWARDFW UDP 192.168.120 50063 8.8.4.4 53
09:35:39 FORWARDFW UDP 192.168.120 60747 8.8.8.8 53
I have been blocking 8.8.8.8 and 8.8.4.4 DNS for months already.
Anyone heard of this Windows 10 behaviour before?
I would appreciate any feed back
