I saw all threads regarding this query in stack overflow. But I Can't find any solution
In the morning when I was trying one project on Visual studio 2010 it was working perfectly fine and now after restart while running Visual studio project I get this error and even my SQL Server 2012 is not connecting what must be the problem ?
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I found Solution to this problem . i'm Instance was proper but TCP/IP was disabled
Go to SQL server configuration tool and open sql server configuration manager . Click on the instance you want to change . Click on protocols and then enable TCP/IP . IT works fine now :)

I'm trying to connect to an SQL database hosted on Azure from a function app I'm building in Visual Studio but I'm getting 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 - An attempt was made to access a socket in a way
forbidden by its access permissions.)
I can connect from the same PC using SSMS without a problem. I've tried connecting to the database using data connections in server explorer in VS but I'm getting the same error. If I connect to Azure with my account in server explorer it shows me a selection of services including SQL databases but there are none listed underneath although my account does have access to the database.
Are there any hidden gotchas I'm missing or settings within VS? I've also tried adding my client IP in the firewall settings but that didn't make a difference either.
After doing some more testing it turned out to be the client firewall that was blocking VS and VS Code from connecting to Azure SQL. It seems there was already an exception for SSMS.
The error message states "Verify that the instance name is correct"
It could be that the SSMS is automatically creating a fully qualified name once you say that it is an azure database.
If you use the short name from Visual Studio, then you cannot connect to the SQL server.
For example "myserver.database.windows.net" versus "myserver".
While I'm connecting visual studio 2010 to sql sever 2008, I'm getting an 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
You are able to connect to your sql server through SSMS ?
If yes then it might be issue with your connection string and else it seems to be issue with credentials or network availability.
More details will be needed in that case.
You can get help in generating connection strings using ".udl" files.
When in try to start azure storage emulator i get the following error.
Probing Failed. Retrying probe for localDB
Probing SQL Instance: '(localdb)\v11.0'.

LocalDB is installed but is not functioning properly. You may be missing prerequisites. Make sure you have .NET 4.0.2 or higher installed.
No SQL Instance found.
One or more initialization actions have failed. Resolve these errors before attempting to run the storage emulator again. Please refer to go.microsoft.com/fwlink/?LinkID=248088 for more details.
I installed .net 4.0.2 also. I tried uninstalling and installing sqllocaldb as well.
Any help is highly appreciated.
I had the same problem.
After installing .NET framework 4.5, the problem is gone for me.
I was also facing same kind of problem when reinitializing Storage Emulator. I used "Autodetect" parameter at command prompt and it worked for me.
DSInit /sqlinstance:(localdb)\v11.0 /Autodetect /ForceCreate
Hope this help to you too.

It would be better if you can check again if local DB is correctly installed and started. Please refer to SQL Server 2012 Express LocalDB for more information.
I have Problem when I run my web project
Error :

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

Then I found in SQL Server Configuration Manager that SQL Server Express stopped
When I'm trying to run SQL Server Express, an error appears
Error :
the request failed or the service did not respond in timely fashion.
Consult the event log or other applicable error logs for details
When I open services.msc to start SQL Server (SQLEXPRESS instance) then this error happen
Error:
Window could not start the sql server (SQLEXPRESS) on local Computer.
For more information , review the System Evemt Log. If this is a non
-Microsoft service,contact the service vendor, and refer to service-specific error code 3417
Any solution to solve my problem ???
been trying to configure an ADO.NET connection for my Visual Studio application but I am running into issues and having no luck at all troubleshooting them. The major error that I run into is:
A network-related or instance-specific error occurred while establishing a connection to SQL server. The server was not found or not accessible. Verify the instance name is correct and that SQL server is configured to allow remote connections (Error 40: Could not open connection to the SQL server)
The steps I undertook to troubleshoot this are:
1. Open up Sql server configuration manager and under the SQL Server Network Configuration, Protocols for MSSQLSERVER,SQLExpress, SQL server 2008 connection string data source I enable each of the protocol names (Shared memory, Named pipes,TCP/IP,VIA)
As instructed I stop the SQL server services first under the SQL server services nodes.
Now I click start, MSSQL server service starts but both SQL Server 2008 and SQLEXPRESS agents do not. Stating the following:
The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details
This might just be the problem as when I attempt to create the connection string , the server name specified is MYWORLD/SQL SERVER 2008. Since the SQL server 2008 agent service refuses to start, the connection fails, leading to the first error message.
Does anybody have any leads on this and can let me know the necessary steps to mitigate this.
The SQL Browser service must be running to connect to a named instance.
Use SQL Servr Configuration Manager under Configuration Tools under Microsot SQL Server 2008 to assign the logon accounts for each service you want to run. Do NOT use any other method to assign user accounts because the correct rights will not be enabled.
