[QUOTE="seanss, post: 940874, member: 54499"] Hi all, am running [B]Windows 10 version 20H2, build 19042.685[/B]. [B]When I try to configure manual DNS under my adapter properties, DNS no longer resolves and my internet does not function properly. Moreover, when I use a VPN service, the internet does not function, presumably due to the same issue. Also, for reference, I've been trying to use Google & Cloudflare's DNS addresses (8.8.8.8 and 1.1.1.1)[/B] Some notes: [LIST] [*]This is not related to my network. This machine has been taken to several different networks, and the issue has persisted on all of them. Moreover, I have configured several [I]other[/I] devices on the SAME network as the Windows 10 machine, all of which can use custom DNS or VPNs with ease. [*]This issue does not persist if I set my DNS to configure automatically. [*]The DNS server I am trying to use is not blocked on my network. Again, I have tried this on several networks so this should not be a concern, but I specifically tested it on other devices and made certain that any and all DNS servers I was attempting to use were in fact [I]not[/I] blocked on the network. [/LIST] Troubleshooting steps already attempted: [LIST] [*]Disabling antivirus (Bitdefender) [*]Uninstalling antivirus [*]Restarting several times [*]Trying to set custom DNS on WiFi as well as Ethernet adapters (internet works on neither when custom DNS is configured) [*]Resetting TCP/IP using netshell "netsh int ip reset" [*]Flushing DNS cache using "ipconfig /flushdns" [*]Disabling IPv6 [*]Booting into Safe Mode with Networking and attempting to make DNS changes there [*]Running Network Troubleshooter (it could not identify the problem) [*]Checking "validate settings on exit" when setting manual DNS [/LIST] Any further information on reasons this might be happening as well as possible solutions would be greatly appreciated!! Windows support was completely unresponsive lol See screenshot for a visual representation of how I am changing my DNS resolvers. On the second page "Internet Protocol Version 4 Properties", I choose "Use the following DNS server addresses" and enter in my DNS resolver. [ATTACH]257564[/ATTACH] [/QUOTE]
