I have two computers with ArcGIS Desktop 10.3 loaded. One is a new install. I am trying to connect to a SQL Server database on the new computer using exactly the same credentials that worked on the first computer. What can be different on this computer that would cause the issue. The error message says something about an older version of SQL Server Client. Is there something else I need to install other than the base ArcGIS Desktop 10.3 software?
