Hi Georgi, thanks for your reply.

1. I have installed SQL Server Express version
2. Imported the Northwind.mdf database

But when I launch the web site I get the following error:

Server Error in '/Telerik.SalesDashboard.Web' Application.

The client was unable to establish a connection because of an error during connection initialization process before login. Possible causes include the following: the client tried to connect to an unsupported version of SQL Server; the server was too busy to accept new connections; or there was a resource limitation (insufficient memory or maximum allowed connections) on the server. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Telerik.OpenAccess.RT.sql.SQLException: The client was unable to establish a connection because of an error during connection initialization process before login. Possible causes include the following: the client tried to connect to an unsupported version of SQL Server; the server was too busy to accept new connections; or there was a resource limitation (insufficient memory or maximum allowed connections) on the server. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)

Source Error:


            Line 116:			Database db = Database();
Line 117:
Line 118:			IObjectScope newScope = db.GetObjectScope();
Line 119:			return newScope;

Please can you help me solve this issue, It is really important that I evaluate these controls.

Thanks

Hi Harry,

This error means that you are trying to use the Named Pipes protocol in order to comunicate with the SQL Server(This behavior is the default and correct one when you use database .mdf files that are not previously attached to the SQL Server instance).

In order to enable the Named Pipes protocol you should use the Sql Server Configuration Manager which you can start from the start menu entry for SQL Server. You can also start it from the mmc.exe executable which you can find in the C:\Windows\SysWOW64 folder.

After starting this tool, you should expand the "Sql Server Network Configuration" node and select "Protocols for SQLEXPRESS". On the right side of the window you can set the status of Named Pipes to Enabled.

Best wishes,
