Take a look at Administrative Tools\Services and restart your process SQL Server (SQLEXPRESS).
Check if the Sql Server service is started in Administrative Tools -> Services.

I installed Microsoft SQL Server 2016 Management Studio on my PC, and when I try to connect to a server, it shows this error:

I don't know what should be the server name. How can I connect to a server?
Run the command SQLCMD -L in a command prompt and you will see your available server names.

I'm trying to connect to a remote database with SQL Server 2008 Management Studio. I got the following error:

I think that I have wrong with my config:
Can someone help me please ?
Steps to find out what the reason is:
Does the SQL server allow remote connections? Main settings SQL Server
Is TCP/IP enabled for client connections and listen on correct IP address / NIC?
Does the firewall on the server allow incoming traffic for the SQL Server port (default 1433)
It is normally one of the 3 points above.
