I am currently researching on this issue. As soon as I can, I will send you a message with my findings. Thank you for your patience and understanding.
I've opened an incident report with our engineers on this issue. Can you please fill out our escalation checklist at https://communities.intel.com/docs/DOC-21212? It will help us to reproduce the problem here, if we can match your configuration exactly.
Sorry for the delay -> the reply email was from lhill and it was filed off into a folder that I was cleaning out today and never noticed that it was for the NUC and from intel.com ... it happens occasionally and I apologize.
We're still evaluating systems and like the NUC but have not yet found an easy workaround. THe NUC has been working flawlessly for about 2 weeks ... EXCEPT... if we have to reboot the system, we need to hook a monitor up to the NUC during the hardware detection stage so we can have video across VNC,
I'll start filling out the incident report for you.
