I have tried any kind of name for Server Name, including ".\SQLEXPRESS", "localhost\SQLEXPRESS", "My PC Name", "MyPCName\SQLEXPRESS" but I still get the same error:
Cannot connect to .\SQLEXPRESS.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

Why is this happening and how to solve this?
My sql server service was running fine but just yesterday, I stopped the service to quickly delete some databases it was using and ever since the instance will not run.
Giving me the error;

"the semaphore time out has expired"

This is a weird error message "the semaphore time out has expired" and I've tried all the possible solution related to the link that you gave
I have two instances:
Default
Named[dynamics\FINANCE]
running on SQL Server 2014. However, when I try to connect to named instance say (dynamics\FINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 - Error Locating Server/Instance
Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number 1450 to the named instance [dynamics\FINANCE]. I also setup the firewall rule to allow access to Port 1450.
What am I missing here?
I'm connecting my SQL Server 2012. But I get below error message, connection failed.
I'm not sure about my server name (I forgot).
Is there anyway to get the database server name, Windows authentication username and password without logging to SQL Server?
Cannot connect to MY-SERVER.
