[Windows] Port binding is not visible with 'netstat' but works correctly.

[mmktomato]

What I did

On Windows Server 2016,

1. powershell -Command "Install-WindowsFeature -Name Containers"
2. Download Docker 1.13.0 from 'https://github.com/docker/docker/releases' and do dockerd.exe --register-service
3. docker pull microsoft/aspnet
4. docker run -d -p 80:80 --name aspnet microsoft/aspnet
5. docker exec -it aspnet cmd
6. echo ^<% Response.Write(DateTime.Now.ToString()) %^> > c:\inetpub\wwwroot\test.aspx

Problem

I get correct response when I do curl http://<container host ip>/test.aspx from other machine (Mac).
But I can't get any result when I do netstat -ano | findstr :80.

@mmktomato weirdly, this works correctly in my Windows 10 insider build but I can reproduce on a WS2016 instance.

It's probably a Windows problem (or netstat problem) more than a Docker one. Pinging @msabansal

@mmktomato @friism I don't see why this should fail. I will investigate and get back.

[friism]

@msabansal it's not failing for me, the port is just not showing up in netstat

[mmktomato]

@msabansal It does not fail as @friism says.
@friism I can reproduce on my Windows 10 (build 14393).
