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.
