docker - Windows Containers hosted on Windows 10 lose their DNS -

i'm facing situation windows based containers lose ability resolve dns.

this happens

to start container test dns resolving docker run -it microsoft/windowsservercore powershell

from inside container

test-netconnection google.com -port 443

fails with

ps c:> test-netconnection google.com -port 443 warning: name resolution of google.com failed -- status: temporary error during hostname resolution , means local server did not receive response authoritative server computername : google.com remoteaddress : interfacealias : sourceaddress : pingsucceeded : false

but should this

ps c:\users\asarafian> test-netconnection google.com -port 443 computername : google.com remoteaddress : 216.58.204.14 remoteport : 443 interfacealias : vethernet (external virtual switch) sourceaddress : 10.98.5.139 tcptestsucceeded : true

i hybernate workstation (windows 10) , on operate hyper-v instances , docker. workstation windows 10 , can tell when problem happens uses dns ip of windows 10 host.

from within container

172.19.128.1 windows 10 host ip.

at same time, when windows 10 host containers stuck, else resolves dns normally.

• any process on windows 10.
• hyper-v instances on windows 10.
• container's hosted on hyper-v instances on windows 10.

restarting machine doesn't fix problem. second time occurs. previous time had reset entire docker installation fix issue. avoid , understand problem , how fix it.

docker version is

as per request of @chris-lawrence comment, following ipconfig /all host , inside container. interesting aspect dns resolution works inside container.

just @ of curiosity, i've checked state of hyper-v instances , off. feeling there strange going on when hyper-v(s). i'm suspicious strange happens when system resumes hybernation when hyper-v instance running. i'll check....

i did check , still ok. hyper-v(s) setup wired netword adapter , such on wifi don't network. in case don't interfere.

update 2 - 20170411

as per request of @chris-lawrence comment, following ipconfig /all host , inside container on network has problem. @ moment of time firewall on container host switched off, @gsa had suggested.
