How to install Active Directory on Windows 2008

Before you start following this article you must be aware this is simply a lab setup and you need to assign relevant ip address, hostnames & domain names which are relavant to your enviroment / organisation.

I will be using the following:

Hostname=PILOT-DC-01
IP address=192.168.1.200
Subnet Mask=255.255.255.0
Domain name=PILOt.LOCAL
Forest = New
Partition: NTFS ( 60 GB )

The Virtual machine used has been installed as of date when this article was written with a default install of Windows 2008 R2 x64 BIT + all MS critical updates.



Configure IP Address details as required. As this is the only DNS server and the first DC we will point the DNS to itself.

We have used the default name PILOT as the NETBIOS name, you can change it if you choose too.



Set you FFL right now we have decided to use Windows 2008 R2 as that is the first DC + no other
DC in this domain. We also would like to research and test the new FFL features. Please make your
