SQL EXPRESS 2016的默认SQL身份验证详细信息

Question

I'm attempting to remotely connect to my SQL Express 2016 server through MS SQL on my local machine however am having extreme difficulties with the authentication.. Well I assume it is an authentication issue as when I attempt connect to connect to it I receive the error message:

The remote computer refused the network connection.

When connecting through the sqlcmd I am using Windows authentication and have no issue, however to connect to it remotely I need to use SQL authentication and have no memory of creating an account so am wondering if there's a default login and password?

I believe this is the issue however it is quite likely i'm doing something stupid so any assistance would be appreciated!

You can create an account that can be used to connect to that SQLExpress instance by using SQL Server Management Studio. Expand the database you wish to create a login for in the Object Explorer. Under the Security folder, you can create a new login by right clicking the Logins folder.

Also make sure that your machine has its firewall configured to allow remote connections, the server has remote connections enabled, and that you are allowing logins for Windows Auth and SQL Server Auth.

You can allow remote connections for a server by opening the SQL Server Configuration Manager . Under the SQL Server Network Confiuration Node, Select Protocols for MYSERVERNAME . Ensure that TCP/IP is enabled.

Here's a guide on setting up the firewall: https://technet.microsoft.com/en-us/library/ms175043(v=sql.110).aspx

You can enable SQL Server Authentication by right clicking your server name in the object explorer in SQL Server Management Studio and going to the Security tab. look for the "Server Authentication" option.
