|If it were me experiencing this, I would go to google and I would search: "PXE-E55: ProxyDHCP service did not reply to request on port 4011"|
If you haven't done that yet, and I suspect you haven't, how about you do that first and do some reading/research on your own. If you can't find a working solution there, then try here.
Remember, Google is your friend
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
