I got this message in Visual Studio 2010, SQL server 2008
A network related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or is not accessible. Verify the name instance is correct and that the SQL Server is configured to allow remote connections.(provider:Shared Memory Provider, error 40 - Could not open a connection to SQL Server
I know the solve is to enable the port number 1433 from SQL configuration tool, but when I open this tool I didn't find any item it is empty.
System: windows8, 64bit
Visual Studio 2010 professional
So what can I do ?

I am working on an ASP.NET project using the .Net Framework 4.8. When connecting to SQL using an alias name, I receive the following error.
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: TCP Provider, error: 0 - Access is denied.)
Additionally, I have verified that my SQL alias configuration is correct, and the connection from SQL server management studio to SQL server appears to be successful.
Unfortunately, I am unable to connect to SQL server from Visual Studio 2019.
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: 52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly installed and that the Local Database Runtime feature is enabled.)
SQL Server Management studio is a client to connect to the SQL Server.
Please tell us which instance you decided to connect, it is in the local machine or remote machine.
Besides please check the server name you input in the box is correct and the SQL Server service is running.
You can check the SQL Server service via the Sql Server Configuration Manager.
I am running SQL Server Vnext (2017) in docker on MAC. I am able to connect SQL Server using command line utility mssql but not able to connect using Visual Studio Code. Can anyone help?
mssql: Failed to connect: System.Data.SqlClient.SqlException: 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.

This error is specific to SQL Server 2017 - Visual Studio Code
I am trying to add a new data connection in Visual Studio. In the Server Name list, I have nothing.
I installed Visual Studio Community and SQL Server Express 2014.
I enabled Shared Memory, Named Pipes and TCP/IP.
In Visual Studio, I can see a server named 'WINDOWS-ORUALD2' under server in the Server Explorer.
In the services, I can see that SQL Server SQL Express is running. I also added port 1433 in the firewall exception and even tried turning off the firewall wall for a moment.
Finally when trying to add the connection, I get the following error:
A network related or instance specific error occured while establishing a connection. Server not found or not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
Thank you for the help
This error occurs when I was trying to connect to SQL Server 2005 which is there with VS 2008.
AN ERROR HAS OCCURRED WHILE ESTABLISHING CONNECTION TO THE SQL SERVER
2005. THIS FAILURE MAY BE CAUSED BY THE FACT THAT UNDER THE DEFAULT SETTINGS SQL SERVER DOES NOT ALLOW REMOTE CONNECTIONS.(PROVIDER:SQL
NETWORK INTERFACE, ERROR:26. ERROR LOCATING SERVER/INSTANCE
SPECIFIED.)
I am doing everything on local machine still it shows error for network. I tried to enable SQL Server browser but its not starting anyway.
How can this be solved?
You have to check for the rights of the folder in which your .net and inbuilt sql server is reside.
You have to full rights of that folder.
