Setting up DC roles in Server Core

One of the new features in Windows 2008 is Server Core - the "thin" layer of Windows operating system which bring benefits of:

1) Less resource hungry
2) More secure
3) Easier to manage (Patch management+++)

Yes, it is in a command shell, but still be able to do major and cools stuff, eg:

1) Domain Controller
2) DNS
3) Hyper-V
4) File Services
5) DHCP and more.

Its definately a great deals for branch office deployment.

However, after setting up Server Core, its only a command shell. How are we going to setup a DC?

In this post, we will like to share:

First of all, we will need to configure the IP Address and put in DNS configuration:

netsh int ip show config will show you the existing configuration.

To configure static IP address on an interface:
netsh int ip set address static

eg: netsh int ip set address "Local Area Connection" static 10.10.100.10 255.255.255.0 10.10.100.254 1

To configure DNS server: (let say pointing DNS to HQ DNS server)
set dnsserver "Local Area Connection" static 10.10.10.10 primary

After configure TCP/IP configuration, its the time to install AD.

Since this is Server Core, DCPROMO GUI will not prompt for you. You will need to prepare the answer file.

NOTE: Please ensure you make ness testing before the deployment. In this scenario, we are setting up additional DC (With same forest, domain with existing AD setup. This is a replica).

EG of the answer file

; dcpromo.exe /unattend:C:\AdditionalDC.txt
; You may need to fill in password fields prior to using the unattend file.
; If you leave the values for "Password"
; as "*", then you will be asked for credentials
[DCInstall]
ReplicaDomainDNSName=MyDomain.local
SiteName=Default-First-Site-Name
InstallDNS=No
ConfirmGc=Yes
CreateDNSDelegation=No
UserDomain=MyDomain.local
UserName=MyDomain\administrator
Password=*
DatabasePath="C:\Windows\NTDS"
LogPath="C:\Windows\NTDS"
SYSVOLPath="C:\Windows\SYSVOL"
SafeModeAdminPassword=MyP@ss123
; Run-time flags (optional)
; CriticalReplicationOnly=Yes
; RebootOnCompletion=Yes

Copy After the and before the . Save it into a file, eg: MyUnattend.txt in to the ServerCore C:\

Then you will need to run the following command to setup the additional DC replica in Server Core:

c:\dcpromo /unattend:MyUnattend.txt

You will then see the results. Happy DCing.Popularity: 1%
