Symptoms

A custom database on a SQL server using AlwaysOn Availability Groups. We need to be able to specify this in the Databases configuration of the package (Adding Parameter MultiSubNetFailover=true) - as need to allow to multiple subnets. However K2 only provides a place to enter a DB Server Name and a Database Name. Where are connection strings it uses stored?
