Downloading components from a shared folder in a network requires setting the local Windows and Remote UNC authentications.
The local Windows authentication refers to the active directory user account in the Control Manager server. The account should have:
Administrator privilege
"Log on as a batch job" policy set
The Remote UNC authentication is any user account from the component source server that has permission to share a folder where Control Manager will download updates.
To enable UNC download:
Access System Settings.
On the working area under ActiveUpdate settings, provide the local Windows and Remote UNC authentication user names and passwords.
Click Save.
Access Manual Download or Scheduled Download.
On the working area under Download settings > From group, select File path and then specify the shared network folder.
