Faulting module ucrtbase.dll after attemtping to start spoold

Hi

I'm in the process of rebuilding a Windows NBU 8.2 media server but can't get the deduplication engine service to start. This is new physical server with a fresh OS installation (Windows 2016) using the same server name and IP address as the original - I decided to also do a fresh install of NetBackup as the original media server hadn't been installed for that long for the hardware failed. The server had an MSDP which was a SAN volume and so still intact and this is mounted on the new server using the same drive letter which I've added to the HKLM\Software\Symantec\Puredisk\agent registry key.

The SPAD service starts fine but the SPOOLD (deduplication engine) fails and returns an error in the Windows event viewer saying:

Faulting application name: spoold.exe
Faulting module name: ucrtbase.dll

We lost two media servers due to a leaking AC unit and the other media server has been rebuilt the same way without issue. I think this may be a Windows thing rather than NetBackup but thought I'd throw it out there just in cause anyone has seen this before or has any ideas on how to troubleshoot further.  

thanks
