Resolution
The first step is to confirm that the account used has access to the location, therefore you must ensure that both NTFS and Share permissions are set correctly for the applied account.
You can test access to the file share by mapping the drive in file explorer from the Discovery Center host using the account mentioned above. If you are unsuccessful in mapping the location, you must review the NTFS and Share permissions for the File Share.
If the access issue does not appear to be related to permissions, you should review the exceptions recorded for the failed indexing activity and the Skimmer.log file to find more detailed information.
If the error message is not obvious, please submit a support ticket including a description of the tests performed and your skimmer log file.
