I'm going to put myself out there as the possible idiot developer who is having the same issue. Here is my connection string, which does not have the same issue as the post before, but is still having the Initial Catalog value ignored.
Data Source=DevSQL01;Inital Catalog=dbStage;Integrated Security=SSPI;Auto Translate=False;Application Name=MRM;
The issue surfaced where an older developed SSIS package updated to VS 2010 seems to have worked until my last update. The server running the SSIS package is SQL Server 2012 connecting to a 2012 database.
Any help would be appreciated.
