I installed SQL Server 2012 but not able to connection to express instance getting below 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) (Microsoft SQL Server, Error: -1)
SQL Server is attempting to register a Service Principal Name (SPN) for the SQL Server service. Kerberos authentication will not be possible until a SPN is registered for the SQL Server service. This is an informational message. No user action is required.
2012-07-20 11:37:08.72 Server The SQL Server Network Interface library could not register the Service Principal Name (SPN) [ MSSQLSvc/VIPUL-MEHTA.XXXX.com ] for the SQL Server service. Windows return code: 0x2098, state: 15. Failure to register a SPN might cause integrated authentication to use NTLM instead of Kerberos. This is an informational message. Further action is only required if Kerberos authentication is required by authentication policies and if the SPN has not been manually registered.
Here is my SQL Server Configuration settings
In management studio I am providing below information to connect:
Server: .\MSSQLSERVER
Authentication: Windows Authentication
In SQL Server 2012 how can I change the settings of Surface Area Configuration.
I forgot the password for SA, so I cannot connect using SQL Server authentication.
Here is TCP IP Settings:
Just open incoming port 1433 in the Windows firewall for TCP access:

I just had this problem solved by following this guy's answer
Can't connect to localhost on SQL Server Express 2012 / 2016
re-installing SQL was the only solution in my case. Learning is always attach 2-3 windows account with SQL Server.
In my case, SqlServer Service was somehow stopped,i think it's because after installing MySql.I changed back it's state to 'Running', and it works now:
Go To Sql Server Configuration Manager
Click on 'Sql Server Services' in the left pane
Right click on the 'SQL Server' in the right pane and click on 'Start'

I have an instance of Azure Hybrid Connections running on a server where SQL Server is installed.
I hosted an WebApp on azure, set up the hybrid connection and I'm consistently getting the same SSPI Handshake error
SSPI handshake failed with error code 0x8009030c, state 14 while establishing a connection with integrated security; the connection has been closed. Reason: AcceptSecurityContext failed. The operating system error code indicates the cause of failure. The logon attempt failed [CLIENT: 1x.xx.xx.xxx]
As described here I added the clients ip in the local security policy.
I also tried adding the DisableLoopbackCheck=1 in HKLM\System\CurrentControlSet\Control\LSA, but it didn't help either.
Do I have to fix it on a database level perhaps?
As per https://github.com/Huachao/azure-content/blob/master/articles/app-service-web/web-sites-hybrid-connection-connect-on-premises-sql-server.md
[AZURE.NOTE] To ensure that your application uses the database that you created in SQL Server Express, and not the one in Visual Studio's default LocalDB, it is important that you complete this step before running your project.
Edit the connectionStrings section to point to the SQL Server database on your local machine, following the syntax in the following example:
I added user credentials to my connection string in appsettings.json and it now works.
I am trying to publish a VS2017 web app to a godaddy domain with authentication on a remote SQL server. The app works fine when run from the Visual Studio environment. I can log in, register, etc and see the data on my SQL Server. When deployed I get ::
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.)]
Fixed - I discovered that the web.config file on the domain server did not get updated with the proper connection string.
I just downloaded Microsoft SQL Server 2014. And the problem is I cannot connect to ' (local) '.
Do you have any ideas how to fix it ?
Error message:
TITLE: Connect to Server
Cannot connect to (local).
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: 2)
Try localhost instead, and if that still does not work, try 127.0.0.1, try your internal address which should look something like 192.168.1.16
Please check the following steps:
Make sure that SQL Server service is up and running(You can check it via SQL Server Configuration Manager)
Make sure that SQL Browser service is up and running(You cab check it via SQL Server Configuration Manager)
Check for TCP/IP and Named Pipes protocols and port. Open SQL Server Configuration Manager and check the SQL Server Network Configuration protocols. You should enable Named Pipes and TCP/IP protocol.
Check to see if remote connections is enabled. Right click on the server name in SSMS and select Properties. Go to the Connections tab and make sure Allow remote connection to this server is checked. If you need to make a change, you must restart the SQL Server instance to apply the change.
Using Visual Studio 2010 10.0.20319.1 RTMRel and SQL Server Express 10.50.1600.1 I'm trying to add a new SQL Server Database .mdf, however, 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

Interfaces, error: 25 – Connection
string is not valid)
I have enabled TCP/IP and Named Pipelines, added Firewall Exceptions for Sql Server, I am successfully connecting from VS in the Server Explorer window.
I would appreciate if someone can pint me to a solution to my problem.
Thank you.
I think that SQL Server must be running locally to be able to create those databases.
I was getting the same error
Started my local .\SQLEXPRESS instance
no more error, and a cute .mdf file was created
According to your error
(provider: SQL Network Interfaces,
error: 25 – Connection string is not
valid)
check here what your connection string should look like

I've been running an ASP.NET MVC application on my IIS 7.5 localhost (on my Win7 Pro box) server with SQL Server 2005 Developer Edition.
I went to put the application on my production server (IIS 7, SQL Server 2008) and am getting SQL Server connection errors. Here is the error I get when I try to browse site root:
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)
I have triple checked my connection string. My host's connection string was in the format XXX.XX.XX.XX,XXXX. Is it normal to have a comma following the IP Address?
Does anyone have any suggestions for something I may be missing?
Thanks.
Take a look at this resource:
http://www.connectionstrings.com/sql-server-2008
A comma after the IP address indicates the port. It should be 1433 unless you have multiple instances.
First of all, make sure that the Windows Firewall (and any other firewall software) on that machine is configured to allow incoming connections to SQL Server. See here for instructions.
Second, check that the SQL Server Browser service in the database server machine is running. This is not necessary in all the connection scenarios, so you may need to provide more details. For example, are you using default listen ports for your server?
