I\'ve recently run into this problem after having used docker toolbox without a problem for a while.
Started happening after windows update?
Windows 10 Home - 64
I got to the same error.
But I don't have "VirtualBox NDIS6 Bridged Networking Driver" in properties of physical connection. A have same driver "NPCAP ..." from wireshark installation. If look at description you can see this is NDIS6 driver.
Then I remove all wireshark packages: NPCAP, WinPCAP, Wireshark and remove VirtualBox.
Restart.
Reinstall Virtual Box. Install Docker ToolBox(Uncheck install NDIS5). And Create default VM for docker.
docker-machine create -d "virtualbox" default
Host-only interface created normally
docker-machine status
Running
That works for me.
