Verify Access to Remote Files, Printers, and Network Resources
Resources using Trusted Agent must be in a network location that is accessible by the Trusted Agent. In addition, the Trusted Agent must run as a domain user on the external network so it can access domain resources such as printers and network resources.
For example, if you used Trusted Agent to run a One-Step Action that writes to a file on a remote network, the Trusted Agent must have permissions to write to files on the remote network location. In addition, users running the One-Step Action must have permissions to access and write to the file location you specify.
