While connecting to SQL Server 2012, I am getting the following error.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2012, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (Provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)
Here is what I did:
I installed SQL Server Management Studio normally but I can't get the server running. How do I set SQL Server correctly the first time?
I want to be able to install this server in my desktop locally and connect to it using Microsoft SQL Server. Any help would be appreciated. Thank you.
Screenshot of my server status as of now
SQLServer start - Log on as LocalSystem
You can try to replace the system databases with you system databases from somewhere else. If not, you can control the firewall.
If you are connecting from the remote server, you check this are.
From the section SQL Server Network Configuration;
TCP/IP Port : 1433 , Named Pipes : Enabled and restart SQLServer

I'm creating a simple UWP application working together with my local DB server I set up with SQL Server Management Studio.
I can successfully set up a connection in the server explorer and run queries in the DB:
However when I run the application I get an error when the connection is being established:
System.Data.SqlClient.SqlException HResult=0x80131904 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: 25 - Connection string is not valid) Source=Core .Net SqlClient Data Provider
I'm not sure if it's a problem with the connection string or what else it could be. I checked the firewall settings and everything seems to be fine. The SQL server settings also allow for remote connection.
Which SQL Server version is running?
Have you tried with the following connection string format?
Data Source=.\\MSSQLServer;Initial Catalog=PapaDario;Trusted_Connection=yes;
Before you connect to your database, some aspect of the SQL Server configuration needs to be changed. First, ensure that you've enabled TCP/IP for SQL Server. You can do that in the Computer Management console. Then make sure that your SQL Server Browser service is running.
I can't connect to a remote SQL Server.
I get this 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)
On the remote machine, the SQL Server is running and port 1433 is open.
In my Visual Studio Server Explorer, the data connection to the remote database shows a little red cross. The state is closed. - I can't see the remote pc in the server name select field. But I can successfully ping the remote computer.
How to connect to the server?
EDIT:
My connection string: {Data Source=wsbd0311\SQLEXPRESS;Initial Catalog=rms;User ID=sa;Password=mypassword} (I can login with this Id and password.)
I allready set "Allow remote connctions to this server" on the remote SQL Server.
EDIT No.2:
Do I need to have an open port 1434 on the remote SQL Server?
Make sure the server is running on the remote pc. Connect to the remote pc and check whether the SQL server instance is running on it by All Programs -> SQL Server -> SQL Server Configuration Manager -> Under SQL Server Services check whether the SQL Server service is on running state. If not try starting the service and connecting.
Furthermore Enable TCP/IP under the Protocols for MS SQL Server which comes under SQL Server Network Configuration.
You may be able to ping the server if the machine is turned on, but in order to connect to the SQL server instance, you should make sure that the SQL server is up and running on the server machine. Check this link for more details
How to Start, stop or restart SQL Server Instance
I'm trying to connect to a remote database with SQL Server 2008 Management Studio. I got 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Erreur : 53)
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.
I'm trying to connect from a local SQL Server Management Studio to a SQL Server hosted in a VM on Azure.
I followed all the instructions from
http://www.windowsazure.com/en-us/manage/windows/common-tasks/install-sql-server/ and created the necessary endpoints:
Somehow, I can't connect to the SQL Server, getting this error
Cannot connect to xxx.cloudapp.net.
ADDITIONAL INFORMATION:
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
(Microsoft SQL Server, Error: 53)
The network path was not found
I already tried to temporary disable the windows firewall on the vm - without success. Any suggestions?
I had the same problem, this troubleshot helped me getting close to the solution:
Use SQL Server Management Studio to connect remotely to an SQL Server Express instance hosted on an Azure Virtual Machine
Summing up, what i did, i don't know if all these steps are necessary, so you should test after each one:
1) In SQL Server configuration manager enable Named Pipes in protocols
2) In the VM add a windows firewall inbound rule for sql server port (in my case the default 1433, in yours it seems to be 1435, make sure it's 1435 in sql server configuration)
3) Make Sure you are using a sql server authentication login (not a windows authentication) if you don't have one create it locally in the VM>MSSMS
4) Make Sure the SQL server is configured for mixed authentication (http://www.katieandemil.com/microsoft-sql-server-error-18456-login-failed-for-user)
5) Make sure sql server browser is running
Hope this helps :)

thanks
Check out surface area configuration. It gives options to do so.
Edit: Enable the Named pipes conenction as well. I guess you are using Named pipe to connect. Also check if the SQL server browser service is running on the DB server.
Check the Authentication mode settings. It may be set to Windows Authentication only, it needs to be in Mixed Mode to accept SQL usernames & passwords.
Also check the Server network configuration and make sure named pipes or tcp/ip are enabled add that the client is using the appropriate protocol.
If everythings are correct, you may want to connect with a upper version, for example you are in SQL Server 2005 and want to connect to SQL Server 2008.
Note that you cannot connect to a upper version.(only same version or older version are granted)
