Converter stops at 1% with Platform-specific error 2338

Hi

I'm trying to P2V a Windows 2003 Server into my vCenter 5.1 enviroment.

Using Converter Standalone version 5.1.0

All ports is open i firewalls, but still I get this error:

FAILED: An error occurred during the conversion:

'Platform-specific error 2338'

I attach a log file here, so if someone can help to figure out what is causing the error, I appreciate that:)
