setup domain-based network as windows [SOLVED}

[Ubun2OS]

i have ubuntu prisice pangolin 12.04 host os and i have installed vbox 4.1.16 on it.
i want to setup domain based network laboratory with ms windows. and i have installed win server 2003 and 2 windows xp as guest.
i have converted server to DC and installed DHCP and more other service. my problem is i want assigen IP to XPes with DHCP server 2003.
now what do i do to confige NIC on server and XPes(bridged , NAT , ...). i don't need to access internet in my simulated network.!!!

Use the internal network adapter in the guest settings and make sure that all guests use the same "intnet name"
The easiest and for most the best way to use and test Windows domains in VirtualBox
Setup Windows Domain in VirtualBox
Don't add the ICS/pFsense if you really don't want the Internet on the test domain.

i'm confuse. i set server and XPes NIC to "internal network", but no client get IP from Server.what is my problem?

That would be a configuration error on the server dhcp.

when i set IP manually , the server is pinged but automatically doesn't
your idea is problems from DHCP? my XPes are memeber of DC but i don't know my problem is from where.

[Perryg]

A server should always be static and not dynamic. The guests will then get their dynamic addresses from the server, if you have set up dhcp on the server. If not then they would need to be static as well. This has nothing to do with VirtualBox but how to configure and use Windows/servers in a domain.
