The default Arbortext Publishing EngineSYSTEM user account doesn't have network privileges, so it can't access any network resources such as a file shared on another server or a remote printer. For example, if you were to write a custom Arbortext Publishing Engine application that sends a print job to a network printer, you would need to configure Arbortext Publishing Engine to run under a specified user account.

If Arbortext Publishing Engine needs to specify a file on a network using a UNC path (uniform naming convention, which takes the form \\servername\sharedir), the default Arbortext Publishing EngineSYSTEM account wouldn't be able to access it. However, a user account can be configured to access files specified by a UNC if the user account has the proper permissions and the UNC file system shares the directories with the Arbortext Publishing Engine user account.

To set up a different Windows user account for Arbortext Publishing Engine, see Configuring a User Account on Windows.
