Morning All,So, the saga continues! Eventually found out from our outsourced developers the Service that connect to our SQL Databases are actually written in Java and use JDBC/JTDS - Despite when being asked they said SqlClient for .NET.Has anyone any experience of JTDS on SQL 2014 AO AG's as it stands the connection will ONLY connect to the Listener when the listener is pointing to a very specific Instance. It refuses to connect on the other two nodes.No one as yet can tell me what version of JDBC or JTDS is being run but the connection string is as follows:[code]<connection-url>jdbc:jtds:sqlserver://LN-PROD-001-IWFR:1433;databaseName=frog1;loginTimeout=0;multiSubnetFailover=true;prepareSQL=2;</connection-url> [/code]And only works when pointing at a very specific node - BUT - I have proved the listener works to all nodes via Management Studio and my own Powershell Script.They all listening on 1433.Any thoughts anyone, or can I provide any more information?Does anyone know a way of determining what version of JDBC and JTDS is being run, so far Google has not yielded anything for Windows Hosts. CheersAlex
