Hi @Anonymous ,
Based on the error message you provided, this error message indicates a problem with the connection to Microsoft SQL Server. First, make sure that the server name and instance name in the connection string are correct. Second, make sure that SQL Server is running on the server machine. You can check this by opening SQL Server Management Studio and connecting to the server. Then, if there is a firewall between the client and the server, make sure that the necessary ports for SQL Server are open. By default, SQL Server uses port 1433 for TCP/IP connections. You may need to configure your firewall to allow incoming connections on this port.
For more information about linking databases, you can refer to the following documentation

Your SQL Server configuration may not include the Named Pipes protocol. However, you should normally use TCP/IP anyway.

How to proceed ahead with this kind of problem ?
