I have developed my first website in ASP.NET with C#. It's a small website which uses Microsoft SQL server 2008 for database and I've deployed it on a free hosting site www.somee.com. It's database is working well on my computer but when I try to access the database on server it gives 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: SQL Network Interfaces,
error: 26 - Error Locating Server/Instance Specified)].
I have updated connection string of the database in web.config and I've used getConString() method for accessing connection string like this:
public string getConString()
{
return System.Configuration.ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
}
What can I do to solve this problem.
Wbsite url is: www.easyways.somee.com
Thanks all of you for your support. I got the solution for my problem. Actually I did something wrong either in creating a database or in using connection string.
Now I recreated a blank database and then I executed the SQL script that I created for my database by navigating to "User -> Managed products -> MS SQL -> Databases -> (Database name) -> New SQL query from file". And also updated the new connection string in web.config file.
This is the connection string I used now:
"workstation id=dataeasyways.mssql.somee.com;packet size=4096;user id=easyways_db;pwd=********;data source=dataeasyways.mssql.somee.com;persist security info=False;initial catalog=dataeasyways"
Your hosting provider provides the connection information for you (in the case of your hosting provider you can see their Help Page here, which shows you how to connect to their DB.
Basically it boils down to logging into their control panel.
In "User menu" navigate to "User -> Managed products -> MS SQL -> Databases -> (Database name)".
Also remember that since this is a remote database there is a small chance that its firwalled from the outside world and only local webservers can access the database.

Can anyone explain why this works
Conn.Open "Provider=SQLOLEDB;Server=tcp:myazurename.database.windows.net;Database=People;Uid=MyUid;Pwd=MyPwd;Encrypt=yes;"
and this doesn't
Conn.Open "Provider=SQLOLEDB;Server=(localdb)\v11.0;Database=People;Uid=MyUid;Pwd=MyPwd;Encrypt=yes;"
I copied my live azure database locally for dev work in Classic ASP and the error message is
Microsoft OLE DB Provider for SQL Server error '80004005'
[DBNETLIB][ConnectionOpen (Connect()).] SQL Server does not exist or access denied.
Azure SQL server version: 11.0.9231
Local SQL server version: 11.0.2318
I can connect using the same details on SQL Server Management Studio so its not a user permissions thing...
Under Security for the server, the user has public server role, the user mapping for the 'People' database is everything except db_denydatareader and db_denydatawriter.
I have also tried (localdb)\\v11.0 which doesn't make a difference.
Any ideas?
OK so I believe the answer is as follows: It doesn't like (LocalDb)\V11.0 it wants a proper instance name like you said in the first place. MACHINENAME\INSTANCENAME OR localhost\INSTANCENAME which I am using as this is going to be replicated for other devs. Also, you DONT NEED two back slashes! My problem is I somehow didn't have a local instance installed. Thanks or your help #Lankymart
I'm going through the Contoso University tutorial found here on asp.net and can't get past the first part due to connectionString problems.
I'm getting this error message after i enter the connection string and try to view the database.

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

I was looking at this msdn blog which mentions the same error under the "Deploying LocalDB on IIS Server " section but i honestly have no idea what it wants me to do.
How can do i fix this error? Is it a problem with the tutorial or am I missing something?
Thanks in advance.
Any chance it is because you forgot to double-escape the backslash? Did you try this:
"Data Source=(LocalDB)\v11.0;Integrated Security=true"
Or even better, you could just use the # mark to disable character escaping for the entire connection string:
#"Data Source=(LocalDB)\v11.0;Integrated Security=true"
Here is what i do in order to fix this problem
You need to install the sql server local db
Copy the local server of your local db in case you don't know here is how to find the local server name(You need to copy the highlighted part)
Update the local server name in the connection string in the web.config file of the Contoso Project
Note that you only need to update the server name in you connection string do not replace the whole connection string with the server name.
Re run all the migration one by one like this
update-database -TargetMigration MigratonName
Build the project and run it.
Change application pool identity from ApplicationPoolIdentity to LocalSystem in IIS for your website application pool and IntgretedSecurity = true in config
will help you.
I am attempting to configure the connection string in web.confg for an ASP.NET app to connect to Azure DB. I am new to this but am familiar with sql configuration strings to SQL Server. How do I configure the login and data source in the connection string I am building. I haven't ever dealt with the cloud like this. If my db name is DB1 how do I set the Azure path for the data source portion of the connection string. NOTE: I know where to configure it in web.config and know to create a connection object.
Thanks.
In the Azure portal, you can navigate to your database's dashboard and click 'Show connection strings' on the right side. See the first screenshot on the below tutorial:
http://azure.microsoft.com/en-us/documentation/articles/sql-database-dotnet-how-to-use/
To answer your original question, "Data Source" means the same as "Server", it is just your server name, i.e. blah.database.windows.net. All of the connection string keywords (including their synonyms) are documented here: https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring%28v=vs.110%29.aspx
i'm currently trying to add a login control to my program, but the problem is, whenever i try to login/register or use the asp configuration tool and go on the security tab, it won't work. It says it's not connecting to the provider. I am new to programming and don't really know what to do with web.config's and for the membership provider to work. Simply put, I can't utilise an SQL server. whenever i try using the aspnet_regsql.exe, it gives me an error saying it can't access it. And whenever i try to create or connect to one, same error. Please help. Thank you in advance.
edit:
I get this error whenever i try registering a user with a blank web.config.
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or

SQL Server is configured to allow remote connections. (provider: SQL

Also, whenever i try adding a new sql server database, it jut gives me an error saying the sql server was not found or inaccessible
I created the login control by following this tutorial
http://msdn.microsoft.com/en-us/library/879kf95c(v=vs.100).aspx
Usually this error occurs when you use SQL authentication by providing user name and password within the connection string, instead of windows authentication. But SQL authentication was not enabled at SQL server level.
Please refer following post SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified to enable SQL authentication at server.
I am using webparts to create a dashboard page. To do that i am dynamically loading the webparts.
strZoneNumber = "zone" + intCnt.ToString();
UserControl UC = (UserControl)LoadControl(row["c_widget_path"].ToString());//Loads the usercontrol
UC.ID = row["c_widget_webid"].ToString();
UC.Attributes.Add("Title", row["c_widget_webid"].ToString());
//UC.Attributes.Add("title" , "Test");
GenericWebPart ucwebPart = wpmDashBoardManager.CreateWebPart(UC);//creates a webpart
wpmDashBoardManager.AddWebPart(ucwebPart, wpmDashBoardManager.Zones[strZoneNumber], ZoneIndex);//adds it to a zone
wpmDashBoardManager.Zones[strZoneNumber].Visible = true;
My webpartmanager personalization mode is set to 'true'
While running this page on the server it is giving me the following error:

SQLExpress database file auto-creation error:
The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory.
The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:
If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist.
If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database.
Sql Server Express must be installed on the machine.
The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.**
Any ideas as to what might be causing this and solutions? Help would be greatly appreciated :):)
Many features of ASP.NET rely on intrinsic application services such as membership, roles, profiles, and personalization. For example, the ASP.NET personalization service uses a personalization provider to save personalized user settings on Web pages. By default Web Parts try to save personalizations into SQL Express database.
This solution was helpfull for me.
In connectionStrings section of your web.config file remove LocalSqlServer connection and add it again with your own preferences:
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="yourConnectionString" providerName="System.Data.SqlClient"/>
</connectionStrings>
Then if you will have 'Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion' error you should create a new database for you to use for personalization.
So, just explore C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regsql.exe and go through steps of the wizard.
Hope it will help.
