Opening an Excel Workbook from a PowerPivot Gallery, we are getting the error that says "Initialization of the data source failed." We have a mix of workstations that can access the file without error every time. There are a few workstations that get the error every time.
Our process to open is to navigate to the desired PowerPivot Gallery, open a workbook, then select "Open in Excel" from the menu. The workbook starts to open and as the worksheet is "painted" the message window comes up.
The SP Log had no errors or warnings.
We are using SharePoint 2010, SQL Server 2012, Windows Server 2008 R2, Excel 2010, IE 9.
If anyone has seen this before and solved it - I'd love to hear how you did it.
Thanks!
Thanks, Scott
