Resolution

This issue has been linked to a missing 'temp' directory in the \SymantecDLP\Protect\ directory.  To resolve the issue, follow the steps below:

1. Access the folder structure on the Enforce Server.
2. Create a directory called 'temp' in the \SymantecDLP\Protect\ directory.
3. Ensure correct permissions (the Protect user should have full rights to access and manage the directory, as well as ownership).
4. Attempt to start VontuMonitorController.
