Good Day
I recently installed docker e.e. 18.09.2 on windows server 2016. The installation was working for the first few day until I ran into an error messages involving the HNS service. I read somewhere that I should reinstall docker in order to remove this issue, but since I’m quite a newbie to docker after uninstalling it I removed the HNS service as I thought that it would be reinstalled with docker. I did this by running the command “sc delete hns” from command prompt. Once docker was reinstalled it was unable to start, as the service would go from starting to stopped almost immediately.
When checking Event Viewer the following error message is shown
“Error starting daemon: a required service is not installed, ensure the Containers feature is installed: failed to open service hns: The specified service does not exist as an installed service.”
I have tried to reinstall the containers feature from server manager but without success as the hns service did not return .Is there any other way to re-add hns as a service?
Kind Regards
Matt
Expected behavior
When starting docker service from task manger, docker should start
