Can't join the domain

[Rob316]

Hi,

I have Ubuntu as host, and Windows server 2012 and Windows 8.1 as guests.
I have Ad, DNS,DHCP installed on the server.
But there is something wrong.
There is no connectivity between the 2 guests.
They can't ping eachother, can't join the domain,DHCP doesn't work.
What must be the Default Gatway of teh server, I am lost whit this, I tried everything, I am stuck

maybe someone can put me in the right direction

Moving to Windows guests since this is really the issue.

Use Internal and set the guests like they were on metal. MS has a forum for server configurations.

As Perry said, this is really a Windows AD question. Follow Perry's advice and put your domain machines in the same internal virtual network. Then proceed as if you were using physical machines connected to the same physical switch. Forget about external network access until you get you domain working.

I have done what you guys suggested , now DHCP works, they can ping each other , but still have problems to join the windows8 machine to the domain.
I messed with the DNS settings, I think that is the problem.
I get the following error;

DNS naam doesn't exist
0x0000232B RCODE_NAME_ERROR

You must use the local DNS on the DC for AD to work, and the client machine must use this DNS only. Do not add any other DNS address, even as a secondary.

I am stuck with this .
I even changed registry setting on the client-pc.
Nothing helpes, is there somebody with the same experience here

thanks in advance

At this point it appears that Virtualbox has established the network between the two guests and they can talk to each other. There is nothing else in Virtualbox to do to get the win8 guest to join the domain. Now you'd need to solve this problem as if you are working on two separate physical computers. Google, Bing, Technet, etc.

Thanks, I got it to work.
I installed a fresh copy of windows 7 and I joined the domain with it

thanks for the replies
