Maybe I'm not communicating correctly what I want you to do. I want you to "reset" VirtualBox. That means no vboxnet1 adapter. That means a Live DVD. That means assigning the default vboxnet0 adapter to a LiveDVD and getting a start/ping/shutdown log.

Sorry, I gotcha.. I will do that shortly..

see screen shoot. I ping the 56.1 - fails .. but can ping the dhcp server 56.2

You didn't have a screenshot, but that's fine, don't need one...

That is *definitely* weird! I mean you get an IP you can ping 56.2. I honestly have no clue why you can't ping 56.1.

Here's my last suggestion:

• Remove manually each and every HostOnly network. Be left with an empty list.
• Uninstall VirtualBox.
• Reboot your OSX.
• Make sure that the output of "ifconfig -a" does not include anything like that:

  $ ifconfig -a
  ...
  vboxnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
  	ether 0a:00:27:00:00:00 
  	inet 192.168.56.1 netmask 0xffffff00 broadcast 192.168.56.255

• Reinstall VirtualBox
• Create your HostOnly adapter.
• Try it with the LiveDVD and just one adapter assigned to the HostOnly network.
