We are facing a very strange issue on scheduling a cache refresh on a datasource to an access database.
the refresh fails with these errors (they are randomly alternating)
[0] -1055784932: Unspecified error: E_FAIL(0x80004005). The exception
was raised by the IDbCommand interface.
2020-01-30 11:40:09.9865|ERROR|116|Error Processing Data Model Refresh: SessionId: 2c213e22-0799-45e0-a89b-38623fb9d385, Status: Error Failed Data Refresh, Exception Microsoft.AnalysisServices.OperationException: Failed to save modifications to the server. Error returned: 'Credentials are required to connect to the File source.
(Source at \\xxxxftp\dnd\xx\xxx events\filiali\xfiles.2019.accdb.). The exception was raised by the IDbCommand interface.
if we connect to the server and launch a process monitor to see what is going behind the scene, the refresh goes fine without any error...
we cannot figure out if and what privilege is missing or if is an issue of other kind (the Antivirus- which we cannot disable- is showing nothing)
thanks
