When i attempt to make a connection to a database on my SQL 2014 sever via Database connections in ArcCatalog using with db authentication i get the lovely "Connection was attempted with an older version of SQL Server Client...." error message. However this is incorrect as the client is up to date. I download and re-installed the 2014 Client.
Also when i use "OS Authentication" i can connect just fine.
ArcGIS 10.3, ArcGIS for Server 10.3, SQL 2014.
The account in question is not a account in our AD just and account in the db
here is the link where i got the latest version of SQL Native Client (Installing SQL Server Native Client)
