SQL server connection

Hi

 

I need to access sql server from a vm using 'Microsoft OLE DB provider for SQL server’.

 

I tested my connection, it works with ‘SQL Server Native Client 11.0’  but not MS OLE DB.

 

How could I fix it? Should I install any dll? if yes, where can I find it?

 

Sorry, I am just learning this stuff.

 

Thank you very much for your help

K

      Good morning

       

      Here is the 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)

      when in Web.config, the provider name is {providerName="System.Data.SqlClient"} 

       

      Thank you
