Basic Installation of Microsoft Windows Server 2012 R2 in VMware Workstation

If you haven't changed the server name after installation, go to Server Manager > Local Server 

Click on the Computer Name and give a name of your choice & restart the server..

Before installing the services like DHCP & DNS, you will have to assign an IP address to the network interface like the way you do in your Windows PC.

To install Active Directory, DNS and DHCP; click on the Manage > Add roles & features on the Server Manager dashboard.

It will prompt "Add Roles & Features" wizard. Basically you will need only to hit Next until where you will asked to select Server Roles..

Select the roles and hit Next all the way to Install. 

When adding roles, it will ask about the features, mostly you will have to continue with Next..

After the installation process completes, you will need to do 2 things which are marked in blue color in the results page. Click on Promote this server to a domain controller..
Because this is a clean installation (no domain nor forest), I am selecting Add a new forest & giving Root domain name as roshanznet.local

Give the DSRM password on the next page and click Next..
For the next pages, you will mostly hit Next until you find the page to Install..

After the reboot you will a yellow flag icon on the Server Manager dash board asking to complete DHCP configuration. Mostly for a basic setup it will just be few Next Nexts..
