Question

At the moment, when I try to register a user using the default Business Template in Silverlight, I am getting an error. Basically I am following a tutorial found on Channel 9 on how to build a business app with Silverlight.

An error has occurred while establishing a connection to the server.

(provider: Named Pipes Provider, error: 40 – Could not open a
connection to SQL Server) (Microsoft SQL Server, Error: 5)

An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the
fact that under the default settings SQL Server does not allow remote
connections. (provider: Named Pipes Provider, error: 40 – Could not
open a connection to SQL Server) (Microsoft SQL Server, Error: 1326)

I found a blog where it identifies the problem, and followed every step, however I am still getting the same problems.

Here is my connection string:-

<add name="SIEventManagerEntities" 
     connectionString="metadata=res://*/EventManagerDBModel.csdl|res://*/EventManagerDBModel.ssdl|res://*/EventManagerDBModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=MONFU-PC;Initial Catalog=SIEventManager;Integrated Security=SSPI;MultipleActiveResultSets=True&quot;" 
     providerName="System.Data.EntityClient" />

Any help would really be very much appreciated!

Thanks

Answer 1

Add
Integrated Security=True;
to the connection string and it should work.
