One of the machine on my network suddenly cannot resolve DNS names anymore (all other machines are fine).
- It's on Windows 10.
- It can ping any IP successfully.
- DNS was working, no user made any change, and then it stopped working. The only thing that happened in between was a forced Windows update (v. 1803).
- "NSLookup google.com" times out
After consulting various online guides, here's what I've tried:
1. Flushing DNS and renewing
- ipconfig /flushdns
- ipconfig /registerdns
- ipconfig /release
- ipconfig /renew
- Letting the DHCP server manage the DNS for IPv4 and IPv6
- Manually setting the DNS to 22.214.171.124 (which I can ping successfully)
3. Repairing TCP/IP Stack
- netsh int ip reset resetlog.txt
- netsh winsock reset catalog
- netsh int ipv4 reset reset.log
- netsh int ipv6 reset reset.log
- Rebooting the machine
- Rebooting the router
5. Network Reset
- Windows 10 Network Reset feature
6. Clean boot
- Disabling all services in "msconfig"
7. Making sure that Microsoft LLDP Protocol Driver is enabled
8. Reinstalling network adapter drivers
9. Disabling the firewall (temporarily)
... so what's next ?
