I’ve put together a couple of how-to instructions intended as a guide to install Active Directory on a Windows Server 2008 R2 server from scratch – that is installing a first domain in a new forest.
Make sure you have a static IP address on your server machine before proceeding with these instructions.
The first part is to install the Active Directory Doman Services role, and to then promote the server to a Domain Controller. This ‘promotion’ phase is where you actually install configure an Active domain along with a DNS server. You can’t continue with installing an Active Directory domain without a compatible DNS server. Since we’re starting from scratch we don’t have a DNS server (one that is compatible with Active Directory), we get to install both in one step.
The second part will install the DHCP server role on the Domain Controller and configure a DHCP scope, i.e. the range of IP addresses the server will lease to clients connected to your network.
