By default, PDF Automation Server installs the Windows service to run under the Local System account.

If within a project you need to monitor network folders or print to a network printer, you will need to change the user under which the service runs. The default Local System Account. does not have permission to access network resources, so it is unable to access network drives or printers. To fix this, you just need to change the service logon user to use a user that does have access to network resources.
