I'm experiencing DNS issues on my Win 10 machine which are the following:
- On system start-up, everything works just fine
- After some time, DNS requests start to time-out
- When requests are timed out, the issue either persists for some time and then it starts working again by itself for a brief period of time (after which the issue is cycling again) or it persists till I Disable / Enable my adapter (which fixes it immediately, again for a brief period of time)
More details:
It affects only DNS. Requests like ICMP or direct IP are just fine. If the connection is established and there is no need to request DNS again for it - it works without any issues for any period of time.
During the time when there is a DNS issue, I can observe the following:
C:\Users\almado>nslookup yahoo.com
DNS request timed out.
timeout was 2 seconds.
Server: UnKnown
Address: 8.8.8.8
DNS request timed out.
timeout was 2 seconds.
Non-authoritative answer:
Name: yahoo.com
Addresses: 2001:4998:58:c02::a9
2001:4998:c:a06::2:4008
2001:4998:44:204::a7
98.138.253.109
98.139.183.24
206.190.36.45
and for the DNS server itself:
C:\Users\almado>nslookup
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown
Address: 8.8.8.8
What I've already tried
- Using another DNS server (from snippets above it's obvious I was using Google public DNS at that time). I've tried using ISP-provided DNS both statically and with automatic settings options in the IPv4 of my network adapter
Resetting all caches, releasing the address and renewing the lease. I've also reset the
winsock catalog
, the full listing would be:ipconfig /flushdns ipconfig /registerdns ipconfig /release ipconfig /renew netsh winsock reset catalog netsh int ipv4 reset reset.log netsh int ipv6 reset reset.log
- Disabling smart name resolution / parallel requests. This is as it's described here. Important thing would be that the mentioned keys didn't exist and therefore I've added them
- Disabling DNS Client Service (via
services.msc
). Disabling / enabling IPv6 in the network adapter options. These actions don't change anything. - Adding
gpedit.msc
console to the system manually (I have Home edition which doesn't have it by default) hoping to enable"Turn off smart multi-homed name resolution"
there. But in the"Administrative Templates"
>"Network"
>"DNS Client"
I do not have this option at all and more - all options which I have there have"Not configured"
state. - Restoring default "Internet Settings". It's "Solution 5" from here.
- Using anti-virus software to perform full scanning in case DNS is throttling me as I might have some malware. Nothing was found.
Of course I've rebooted the machine after mentioned modifications. It worth mentioning that the issues started to happen not long ago - same machine was working just fine without troubles and nothing was changed manually - but I believe issues started to occur after latest Windows update (not 100% sure about that).
I've also checked that it's not some firewall-related issues by disabling firewall completely and still observing same issue after some time.
