CAUSE
The source of the error is because the processing nodes can not find a file. All nodes must be able to reach this site. However, a problem can occur if Legal Processing is set to use a local path in the “Shared Folder Path” setting. This path needs to be UNC\Share path in a cluster because all nodes will use this value and services that use this path cannot access drives mapped in user settings.
RESOLUTION
In Legal Processing go to Global Settings.
In the Shared Storage Location section, specify a UNC path that is accessible for all nodes.
