I recently had to move a PowerPivot report from one terminal server to another. I was able to get the PowerPivot Data Connections up and running without much trouble. When I click Test Connection, it is successful. Part of this involved changing the provider (within PowerPivot) from SQLNCLI10 to SQLNCLI11.
However, the Workbook Connection String does not work. It seems that the workbook is still looking for the SQLNCLI10 provider.
Can someone please explain (or direct me to some documentation) how to update the Workbook Connection String?
