I have an application which connects to SQL Server 2008 via windows service.Basically,windows service pics up a configuration file to get connection details like instance name , user name & password.Currently this windows service is failing to start with following error 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Application server and DB server are different machines.I can connect to SQL Server via SSMS from application server without any issue. Also I created a UDL on app server and it also connected fine to DB server. Any help here is much appreciated.
Check the account under witch windows service is running- most possible that account is not allowed to make connections to other computers.

I just installed SQL Server Management Studio and it auto creates a server with your PC name to connect to, but it doesn't connect - all I get is this error. I tried reinstalling and also there's no server with that name in the services to start
TITLE: Connect to Server
Cannot connect to DESKTOP-7UA72F9.
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)
It looks like you've installed Management studio only. Server doesn't come with it. Could you provide additional info on what steps you went through exactly? What install files did you use?
If you're looking to play with MS SQL Server, there is an Express version, it's free.
I have create a SQL Azure database on the Azure portal, now I want to connect to it using SQL Server Management Studio. I've set my properties like this:
Server Type:Database Engine:
Server Name:[mycred].database.windows.net
Authentification: SQL Server Authentification
username: myusername
password: mypassword
But when I try to connecting with these properties I get 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: Named
Pipes Provider, error: 40 - Could not open a connection to SQL Server)
(Microsoft SQL Server, Error: 53)
Whereas I have configure firewall on my SQL Azure database. How to solve this issue?
Your request has not left your machine that's why it is returning network error. There could be several issues and first start with SQL Server Management Studio. You must have SSMS R2 2008. Any non R2 version will not work.
Here is a list of test you would need to perform to troubleshoot the problem and apply solution:

I'm trying to call a sproc from EntLib (MVC3, EntLib5, SQL Server 2008). I'm using the default instance of SQL Server and can connect to it just fine from SQL Server Management Studio. I've tried everything I could find online and nothing gets me connected. The service is running as LocalSystem. Here's the connecction string:
Server=local;Database=Test;Trusted_Connection=True
Here's the error message I'm getting:
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)
Server should be "localhost", not "local", and the "TCP/IP" and "Named Pipes" protocols should be enabled in SQL Server Configuration Manager. Also, if you want to use a trusted connection, you might need to enable Windows Authentication on your MVC3 application, otherwise provide a username and password in the connection string as well.
If you are working with your local SQL Server you need to use localhost or "."
I get the error message below when accessing Reporting Services through a browser
URL used: http://<name of server>/ReportServer
Reporting Services Error
The report server cannot open a connection to the report server
database. A connection to the database is required for all requests
and processing. (rsReportServerDatabaseUnavailable) Get Online Help A

a connection to SQL Server. The server was not found or was not
accessible. Verify that the instance name is correct and that SQL

Have you verified that the configuration is correct? Use "Reporting Service Configuration Manager" which is installed with SSRS. Step through the screens looking for problems; try applying the configuration and make sure databases exist and have correct permissions.
Try running RSConfigTool.exe or Report Services Configuration Manager from Windows and check if the server is accessible
I have been unable to configure my SQL Server 2008 Express to allow remote connections. I followed the instructions from this guide: http://www.linglom.com/2009/03/28/enable-remote-connection-on-sql-server-2008-express/ .
I am still getting the following error:
Cannot connect to 00.00.00.000
Additional information:

I also configured the firewall as defined in http://blog.sqlauthority.com/2009/05/21/sql-server-fix-error-provider-named-pipes-provider-error-40-could-not-open-a-connection-to-sql-server-microsoft-sql-server-error/ . As a test I even turned off the firewall, but nothing changed, so it is not the issue.
Update under server name, it only says the IP address. Do I need something more?
In the Server name field of Connect to Server, I had myipaddress. I changed it to myipaddress\SQLEXPRESS and it works.
In addition, once this was working without the firewall I applied settings as defined in http://www.sevenforums.com/system-security/58817-remote-access-sql-server-express-2008-windows-7-a.html to make the connection work with the firewall turned on.
Do you have sysadmin rights in sql express? It may be that your user account doesn't have the necessary permissions. There is a script on codeplex that will add you logged on account as a sysadmin.
