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

I'm using Advanced Installer Architect 17.5 to create an .exe setup file. During my installation process, I need to run some SQL Server queries.
When it comes to creating a SQL connection, I could not find the right configuration to help me pass the connectivity test.
I've tried many different scenarios, I've used SQL Server or SQL Server Native Client 10.0 to connect to the database. I've also used Windows authentication mode (Trusted Connection/Impersonate user) or database logins, but all of them lead to an error
Failed to establish connection
in the test process.
Can somebody point out what is my error in this process?
I've brought screen shot for details. Please not I've also disabled Impersonate User and tried to login but all of them failed.
I've used many configurations for Server parameter such as . or .\ServerName or local.
I've also tried SQL Server 2008 and SQL Server 2017. Using the same parameters I can connect to server using SQL Server Management Studio.
I would try a couple of things first (If you haven't done them already):
Make sure your server is configured to allow remote connections. You can check this in SQL Management Studio, right-click on your server, click 'Properties' and go to the 'Connections' section.
Make sure the ODBC driver to connect to SQL Server is installed. You can get it from here -> https://learn.microsoft.com/en-us/sql/connect/odbc/download-odbc-driver-for-sql-server?view=sql-server-ver15
I have Visual Studio Enterprise 2015 installed (on Windows 10) and need access to SQL Server. I thought the server was included in the installation of VS, but begin to suspect that I was wrong.
I can see programs under Control panel, like SQL Server 2012 Native Client, SQL Server Express 2014 Localdb, some different management tools, etc.
I concluded that the SQL server and management tools were integrated, but can not run the server via my VS:
Can not connect to ... A network-related or instance-specific error ocurred 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 configurated to allow remote connections. (provider: Named Pipes Provider, Error: 40 – could not open a connection to SQL-Server) (Microsoft SQL Server, Error 2 ... Unable to find the file.
I realized that I need to configure the firewall in some way, perhaps even make further adjustments/configurations. But I also think that I still have to install? How do I make these configurations?
Do I need both the SQL Server and Management? Or is it enough with the VS for management? If installation is needed, does it matter which version I choose? (I have access to DreamSpark: Web Edition, Express, ordinary etc. - 2014 and 2016). As you can tell I am a total beginner and need some help to point me in the right direction…
Using Visual Studio Community 2015 and SQL Server Enterprise 2014.
I have been trying to find a solution for this since yesterday. I'm getting this error message:
Network-related or instance-specific error. Error 25 - Connection string is not valid.
Here is my connection string.
<connectionStrings>
<add name="LocalSql" connectionString="Data Source=SERVER;User ID=Administrator;Password=***********;User Instance=False"/>
I can connect to the server from Visual Studio (through Data Connections and SQL Server Object Explorer). I can also connect to the server using SQL Server Mgmt Console.
Remote connections allowed. In Visual Studio Tool>Data Connections: Sql Server instance name is MSSQLSERVER.
I even enabled all transport protocols. TCP, Named Pipes, Shared Memory. All client protocols are also enabled.
SQL Server is running alongside Visual Studio when I attempt to create the service-based database/Sql server database from Solution Explorer.
Has anyone got this working with this setup? Visual Studio 2015 and SQL Server 2014 are both running from the same computer. Or is this one of those broken software interfaces that we should just ignore?
As always, your time is much appreciated.
In your connection string do specify the SQL Server instance name if it's a named instance rather a default instance. Also, specify the initial database name to connect to like below along with the Provider Name
connectionString="Data Source=SERVER\instance_name;Database=Sample;User ID=Administrator;Password=***********;User Instance=False"; Provider="System.Data.SqlClient"/>
I am trying to connect to ms sql server but I get error: provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server.
This is in Windows form application. This application works correct and connects to MSSQL Server in other all other PCs but not in mine. This server is in local network. So I guess problem is not in MSSQL Server.
Before 2 months this application worked on my PC as well, as I coded it with visual studio 2008 and was debugging, all worked great. After that I have installed Visual studio 2012 and MSSQL express 2005 and 2008. So these changes have been made on my PC. Now I go back to edit my application and it cannot connect anymore.
I have searched the web and found that these servers 2005 and 2008 could be the problem. I have removed them both from my PC. Now I have Visual studio 2008 and Visual studio 2012. Could it be the problem for my connection to SQL server? There is no problem with connection to oracle or My SQL.
I cannot remove Visual Studio 2012 as I have code with it. Please help.
I don't think the problem is about Named Pipes or Visual Studio 2012, especially if other PCs in the network can connect to the server...
have you restarted your SQL server?
can you ping the server from your pc?
have you checked and rechecked the connection string?
can you create a connection to your database using Data Sources (ODBC)?
When you say "Now I go back to edit my application and it cannot connect anymore." do you mean in visual studio, debugging it OR you mean a deployed/installed version of your program?
If you're debugging, are you 100% sure you're trying to connect to the right SQL server and not localhost? I would definitely triple check the connection string and anything related to that
solution:
when in doubt, always write your IP address in connection string...
Mostly the problem will occur due to Firewall issue, did you try disable the firewall and test?
Google found me this. Please try to perform these instructions an let us know.
UPDATE
To enable named pipes and TCP/IP for Microsoft SQL Server 2005:
Click Start > Programs > Microsoft SQL Server 2005 > Configuration Tools > SQL Server Configuration Manager.
Under SQL Server 2005 Network Configuration > Protocols for MSSQLSERVER:
Double-click the protocol name TCP/IP and set the property ENABLED to Yes.
Double-click the protocol name Named Pipes and set the property ENABLED to Yes.
To restart MS SQL 2005 service, run the following commands in the command prompt window of the Parallels Pro Control Panel server:
net stop mssqlserver
net start mssqlserver
Can you Connect to another server from this PC?
If yes you can then maybe their something in your server prevent your PC from connecting.
if no then their is problem in your PC.
Also try connect using Server IP not instance name.
From all of the information you have provided I have a concern that this may be your SQL Server Browser service that is pointing you to one of the (now removed) servers that you had on the machine in question. Can you open the remote server from SQL Server Management Studio using the connection details in your web application from this computer?
I already have SQL Server Enterprise 2012 on my PC and the service that is running is MSSSQLSERVER (found on SQL Server Configuration manager).
I am trying to attach a database which requires SQL Server Express!
I downloaded SQLEXPR_x64_ENU and installed it, unfortunately SQLEXPRESS is not shown in my Configuration manager.
What shall I do to attach this database?
The attempts I've done:
First I tried with SQL Server Management Studio: while attaching gives this problem message:
An error occurred when attaching the database(s). Click the hyperlink in the message column for details.
and the progress box shows:
Error occurred.
While I try to add a data connection to the database in VS2012 I receive these errors:
If I use Data Source "Microsoft SQL Server" I receive this message:
The user instance login flag is not supported on this version of SQL Server. The connection will be closed.
If I use Data Source "Microsoft SQL Server Database File" and I browse the database file, I get this error message:
A network related or instance specific error occurred while establishing oa 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 interface, error 52 - unable to locate a local database runtime installation. verify that SQL Server Express is properly installed ant that the local database runtime feature is enabled)
As you see SQL Server Express is required.
If you correctly installed SQL Express on a laptop that already had the MSDN developer version, you should see two instances in the services.
MSSQLSERVER - developer version
SQLEXPRESS - express version
SQL Express does not come with services like the SQL Server agent. But it should be listed as the database engine SQL SERVER (SQLEXPRESS) under the configuration manager, SQL Server Services.
Make sure this service is started as well as the Browser service. Under network configuration, make sure TCP/IP is enabled. Under client protocols make sure TCP/IP is enabled.
Since you have the development version of SQL Server, you can connect and manager the express instance like the default instance. Just use your SSMS query window with the correct TSQL.
Here is a link on my blog on how to create a database for attach.

Please respond back if you still have issues with a screen shot or two of the settings I just discussed.
