I had SQl Sever 2008 R2 Express on my production server and i upgraded it to SQl Server 2008 Web Edition. Even since i upgraded my websites do not get connected to database. I was wondering what should be changing to connect to the databases. This is a Website in VS 2008.
This is the part of the code where i have the connection string.
connstring = "Data Source=198.57.59.70;Initial Catalog=Tracking;Integrated Security=SSPI;";
I get the error when connecting to database as "System.Data.SqlClient.SqlException: 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."
Can someone suggest where i am doing wrong, Please!!
Thank you in advance!

I want to connect to a SQL Server 2008 Express but I get this error - how to solve it?

This is an exhaustive list of troubleshooting techniques to use when
you cannot connect to the SQL Server Database Engine.
I'm connected to analysis server:localhost\sqlr2.
I'm using windows authentication,so user name and password are all grayed out.
I'm trying to deploy a project from Visual Studio BI to SQL Server 2008R2 analysis server and get the following errors:
Error 1 Internal error: The operation terminated unsuccessfully. 0 0
Error 2 OLE DB error: OLE DB or ODBC error: Login timeout expired; HYT00; A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.; 08001; Named Pipes Provider: Could not open a connection to SQL Server [53]. ; 08001. 0 0
Error 3 Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of 'Max Min Manufacturing DM', Name of 'Max Min Manufacturing DM'. 0 0
It looks like your datasource is set up wrong. When you process, what server is the cube pointed at? What account does SSAS run under? How have you set up the connection string in the datasource? Are you seeing failed login attempts in the SQL Server logs?
Error 2 OLE DB error: OLE DB or ODBC error: Login timeout expired; HYT00;
A network-related or instance-specific error has occurred while establishing a
connection to SQL Server. Server is not found or not accessible.
Check if instance name is correct and if SQL Server is configured
to allow remote connections.
I'd focus on this. I assume you must be able to connect to SQL Server in Visual Studio to build your cube, so I guess Analysis Services doesn't have permissions. Check your connection strings.
You say you're using Windows Authentication, so does the service accounts that Analysis Services runs under have access to the required database?
I would like to share my experience with this error and how I discovered the solution.
Hope it helps!

In my case I was connecting with a wrong provider, I was trying to connect using SQL Server Native Client 11.0 to MS SQL Server 2005 DB which caused my similar problem.
When I reverted to version 10.0, worked perfectly!
I have a server that has SQL Server 2008 R2 installed but my application uses SQL Express 2008 R2 - do I need to install SQL Express as well? The error Im currently getting is:
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 can create your database the SQL Server and connect with the correct connection string. You can not attach your Database files like in SQL Server express though.
There is no need to install SQL Server Express.
A common connection string to connect to SQL Server is:
Data Source=yourServer;Initial Catalog=yourDatabase;Integrated Security=SSPI;
Replace yourServer with the servername (in the form of Server\instance) and yourDatabase with the name of the database you wish to connect to.
The following connection string for SQL Server Express does not work on a standard SQL Server:
Server=yourServer;AttachDbFilename=c:\data\yourDatabase.mdf;Database=yourDatabase; Trusted_Connection=Yes;
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 am having issues to connect to a database from a C++ program (VS 2008).
I have created the database using SQL Server and both SQL Server and SQL Server Browser are running, TCP/IP and Remote Access are enabled.
I can connect to my database using sqlcmd, but when I use:
System::Data::SqlClient::SqlConnection ^_SqlConnection = gcnew System::Data::SqlClient::SqlConnection();
_SqlConnection->ConnectionString = "Data Source=MyComp\SQLEXPRESS; Initial Catalog=DbName; Integrated Security=True";
_SqlConnection->Open();
I get the classic error
Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
I have copied the connection string from the database properties found in the Server Explorer of VS, so I guess it's correct.
Thanks a lot for any help.
Found the solution. Correct syntax for connection string is:
"Data Source=MyComp\\SQLEXPRESS; Initial Catalog=DbName; Integrated Security=True";
With 2 back-slashes \\ in the server name.
