PeopleSoft nVision with Non-Interactive Service Accounts

We are currently transitioning from a hosted environment to an internally managed server environment. Under our organization's security policies, service accounts are not permitted to log on interactively to servers.

We have successfully configured the Application Server, Process Scheduler, and PIA to run under the service account, and the PeopleSoft application is functioning as expected. However, we've encountered an issue with nVision.

When an nVision report is submitted, we can see the Excel process start in Task Manager, but the report eventually times out without completing. Our working theory is that Excel is attempting to perform first-time initialization or profile-creation tasks.
