I have a MS Access db as a data source which will not refresh at all.
After creating a local copy of the data source, I have set the correct UNC path in favour of the drive name, I have set the authorisation to allow refresh access and published the data source to the server.
When I try to refresh teh data source it just fails with the following reason
com.tableausoftware.nativeapi.dll.DataSourceException: Database error 0x80004005: Your network access was interrupted. To continue, close the database, and then open it again. Unable to connect to the Microsoft Access database "//-------------/Tableau/External data sources/Survey Monkey/Customer Survey master database - 2017.accdb". Check that the path is correct and that you have access privileges for the requested file.
Is this happening when you try to refresh from Desktop or from Server?
