Исключение: поставщик именованных труб. Ошибка 40-Не удалось открыть соединение с SQL Server

Question

Я создал приложение форм Windows, в котором есть несколько отчетов. Я создал их с помощью ReportViewer и набора данных. Я застрял на исключении, возникшем, когда я установил приложение на клиентскую машину. Моя клиентская машина имеет сервер sql 2012 и базу данных, запрошенную для приложения. Приложение отлично работает для входа и добавления записей клиента, но бросает исключение, когда я пытаюсь открыть любую форму, содержащую отчет.

Connction строка:

SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=db_Lodge;Integrated Security=True"); 

Детали исключения являются:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging ************** 
To enable just-in-time (JIT) debugging, the .config file for this 
application or computer (machine.config) must have the 
jitDebugging value set in the system.windows.forms section. 
The application must also be compiled with debugging 
enabled. 

For example: 

<configuration> 
    <system.windows.forms jitDebugging="true" /> 
</configuration> 

When JIT debugging is enabled, any unhandled exception 
will be sent to the JIT debugger registered on the computer 
rather than be handled by this dialog box. 

Что я должен сделать, чтобы решить эту проблему?

Answer 1

1. Проверьте все ваши ConnectionStrings

2. Проверьте информацию ReportServer:

   reportViewer.ServerReport.ReportServerCredentials = new CustomReportCredentials("user", "pass", "domain"); 
   reportViewer.ServerReport.ReportServerUrl = new Uri("http://youipaddress/ReportServer/"); 
   reportViewer.ServerReport.ReportPath = "/App/AppReport"; 
   reportViewer.ServerReport.Refresh(); 
   

Answer 2

Добавить подчеркивание в Trusted Connection поэтому становится Trusted_Connection.

Это asside, несколько вещей, которые могут вызвать эту ошибку, скорее всего, это один из первых двух перечисленных:

• Убедитесь, что служба Windows, SQL Server работает.
• Проверьте правильность имени сервера (DataSource). Использование только точки указывает экземпляр по умолчанию на локальном компьютере. Если вы используете SQL Express, обычно это с именем экземпляра и будет обозначен как .\SQLExpress.
• Учетная запись Windows, которую вы используете (поскольку ваша строка подключения настроена на использование доверенного соединения) не имеет разрешения на базу данных db_Lodge.
