virtualbox.org

I've trying to install 2 machines, one with windows 2012 server and the other one with windows 8.1, iv create domain for the machine, and everything, when i try to login in the domain with my notebook, it's ok, but the windows 8.1 on virtual box don't find the windows 2012, i've try to ping the machine, and its work normaly, but with the domain windows say thats cant find the adress. Any one could Help me ?
- All lan are with bridge mode
- Promiscuo mode are able to allow everything
- The ips of the machine are correct.
- DNS are correct to.

Just for you to know linux as a host

Don't use bridge, you'll be using the DNS of your LAN, where you should be using the DNS of your Windows server for the domain.
See the Setup Windows Domain in VirtualBox tutorial.

Is there another way to do this ?!

Did you read the topic I linked?

Yes, I read, but my linux has hi own firewall, and installing xp as a guest, it will be another machine, and i already have 3 windows guests, this will be the forth, i've tried the PFsense, but my machine has blocked, and i have to reset it, i don't know why, even if i haven't try to configure it all. that's why im asking if there is another way.

You don't need to redo exactly what is written in the topic, it is only to give you the general configuration you want to have, e.g. don't use bridge for the Win8.1.
You are mixing three things here : how to configure an AD Domain, how to configure Networking, how to configure Virtualbox to map your requirements.
Before going any further, you will need to work on the 1st and 2nd point, then you will understand my first reply and the topic I linked to you.

There are lots of ways to do it, but they all require that you know how networking works and also how Active Directory works. Once you have that basic knowledge, the VirtualBox bit is easy.
