In Get Data > Databases & More > SQL Server Analysis Services there is a connection listed that says it is published by our prior BI Developer. How can I remove this connection as it's not running? (Very likely due to incorect password. And for the life of me I have no idea how to find which computer the Data Gateway is running/not running on.)
@DouglasABailey I'm not aware of Power BI storing the actual connection string for the AS Connectors.. What you are looking for is the "Data Management Gateway Host Service" in Services on the machine. I would start with taking a look on the machines that contain the AS instance, as that is the most likely place.
