Hi,

We have a Business layer in our .NET 2.0 project that uses LLBLgen DAL code.

Also have a Business.Test project that test business layer.

In MPS.layers.business.test.dll.config file I have Database connection string.

SQL server 2005 and NUnit and .NET project on same computer.

When I open the Business.Test.dll file in NUnit and run the test I get below error:

MPS.layers.business.test.PatientTest.PatientFetchTest : System.Data.SqlClient.SqlException : 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)

Could you please advice why it is not reading the connection string.

Hi,

It is working when I change the setting as per attached image.

Why it is not working while it is setup as Local connections only in Remote Connection - via SQL Server 2005 Surface Area Configuration screen.

'Local connections' are often connections to 127.0.0.1. Any connection to another IP address on the same machine is considered an external connection. This is generally similar in most database systems.
