Problems with NAT Adapater since upgrade to Ubuntu 12.10

I was running Ubuntu 12.04 w/ VirtualBox installed. I was using the NAT interface to connect to everything. Basically running VBOX for testing some things and a Windows VM for Netflix..
Was back to working in my VMs today and noticed that I was unable to connect to the internet. In the VM settings I'm using the NAT adapter, however I noticed there is no NAT adapter in the Network Settings under Preferences in VBOX.

Not quite sure what happened but wonder what is going on?

I noticed there are some posts about changes DNSMASQ and configuring a bridge mode, but this worked out of the box under 12.04 and since the upgrade this no longers work.

Need some help please

Known bug of (K)Ubuntu 12.10.
Try the following two command lines :

VBoxManage modifyvm "name" --natdnshostresolver1 on

VBoxManage modifyvm "name" --natdnsproxy1 on

if that does not work, install virtual box 4.2 :

Uninstall virtualbox from your computer

sudo apt-get remove virtualbox

also uninstall the guest-addition iso as the 4.2 version contains a new one :

sudo apt-get remove virtualbox-guest-additions-iso

Download and install virtual box 4.2

echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -

sudo apt-get update

sudo apt-get install virtualbox-4.2

When running virtualbox the first time it will ask you to update guest-addition module with the one downloaded.

Enjoy !
