I am going through a unexpected error. I am always getting the error "Error response from daemon: unauthorized: authentication required" whenever I am trying to pull microsoft/mssql-server-windows:2017-latest by using the blow command.
C:\Users\Administrator>docker pull microsoft/mssql-server-windows:2017-latest
Surprisingly I am able to login when I use docker login, I am not sure what I am missing here. I am also able to login to https://hub.docker.com/ with the credentials I have. The problem exists only when I try pull.
C:\Users\Administrator>docker pull microsoft/mssql-server-windows:2017-latest

I found out the reason. It was the problem with the repository name. I searched for mmsql in the hub.docker, there I could not find any repositories with the name microsoft/mssql-server-windows:2017-latest and I selected mssql-server-windows-express and run the pull command as below.
docker pull microsoft/mssql-server-windows-express
After I enter my credentials it was pulling the repository as expected. It seems like we get this authorize error when the repository name is invalid.
