Sometimes you just want a new Domain created quickly for a bit of testing. Given that Windows 2008 ships with server core, a light footprint version of the OS, it’s ideal for being the domain controller. As I am fairly inexperienced with Server Core I had to search all over the place to find information on how to go from a vanilla server core build, to a dc running a brand new domain. I figured out a set of commands that achieve this, so thought I would share them with the world.
Netdom renamecomputer <OldName> /NewName:<NewName>
netsh int ip set address "Local Area Connection" static 192.168.0.210 255.255.255.0 192.168.0.1 1
Netsh interface ipv4 add dnsserver name=”<idxname>” address=<IP Address> index = 1
Install DNS Role
start /w ocsetup DNS-Server-Core-Role
Create New Domain
Another cool Server Core reference can be found on Mark’s blog here:
Hope this helps
One of the things I have pointed people to a few times recently  is the Windows Server Core document
The Read-only Domain Controller is one of the new and most existing features of Windows Server 2008.
In my case i have seen that i had to first disable the firewall on the server core, only then could i ping that machine...is that a requirement?
