I began running the Complete FTP Server under a Windows service account rather than the Local System account. As a result, one of our vendors was not able to push files to our server. The error message from the log is: 2021-03-10 02:53:26,937 DEBUG WindowsAdapter [Session.168:Default Site:FidelityProd:184.108.40.206] Exception thrown while complete-ftp was accessing 629_RMD_20210309.DAT - System.UnauthorizedAccessException:Access to the path 'C:\SFTP\Fidelity Prod\629_RMD_20210309.DAT' is denied.
This change only affected one vendor and not others.
Any ideas why this would have happened?
