Resolution

This issue has been linked to a missing 'temp' directory in the \Symantec\DataLossPrevention\EnforceServer\<version>\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 \Symantec\DataLossPrevention\EnforceServer\<version>\Protect.
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 SymantecDLPDetectionServerControllerService.
