Hi, iam currently want to move the Umbraco Database (try with clean installation (Umbraco 6.x and 7.x)
to SQL Server Express 2012 (Running on Windows Server 2012) . But with no success. i got always the following error message.

on the sql server i have set everything to allow remote access . On the Windows Server i have had enabled the ports 1433 and 1434 .
When test over administrative tools->odbc connections->SQL Server Native Client i can successfull connect to the database.
when i try a small .net programm with simple connection string to the sql server 2012 it works too.
but with umbraco i cannot connect. Why?
i have soon already test the server with ip, with instance name with port but nothing .

anyone of you an idea?
regards stefan 

The database configuration failed with the following message: 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.
