⇒ A computer is having Windows server 2008 or 2012 versions edition.

⇒ Install DNS server before Active directory installation.
⇒ Minimum 5GB NTFS Partition of disk space is required.
⇒ Check all the Pre-requisites are fulfilled and Log in as Administrator.
⇒ First you need to ADD ROLE of “DNS” and Then “Active Directory Domain Services”.
