I am creating a local cube through a web page and everything is working
properly when I am debugging or using a default instance but if I am using a
named instance, the following exception is returned:

x= Exception:File system error: Error opening file; \\?\C:\Program
Files\Common Files\System\Ole DB\MDTempStore_1088_1_fm3by.tmp is not a disk
file or file is not accessible.

Microsoft.AnalysisServices.AdomdClient.AdomdComman d.Execute()


The role defined for the cube is:

General tab: Read definition

Cubes tab: Access: read

Cubes: Local Cube/Drillthrough Access


Thanks,
