DNS Resolution Problem on Ubuntu 14.4 LTS

I have a Windows 8 host machine running VirtualBox and a running a Ubuntu 14.4 LTS Virtual Machine.

In the Ubuntu VM, I can access and resolve DNS for every external site (Ex.: www.google.com) and I can resolve intranet sites by first name, ex.: anothermachine.

If I use the full qualified domain name, like anothermachine.mywindowsdomain.local, which is valid on the windows, this name can't be resolved inside the Ubuntu VM.

This box was created by vagrant.

This box is using NetworkManager.

I'm using ping to check if the host name is being resolved. Doing a ping mybox works and doing a ping mybox.mydomain.local don't work. Both approaches works for any other machine on the same network.
