Hello Friends,

Sometimes life is so uneasy that you didn’t get time for the work which you like the most. Now those days are gone so I am back.It’s been months I haven’t written anything . I have received lot of mails through blogs and LinkedIn which I tried to reply.

So, How to Install Active Directory in Windows Server 2012?. I will try to provide exact way to install and configure Active Directory in new world.

3) Select Forest functional level and Domain Functional Level. Here I am considering that all my servers are server 2012 . If there are server less than window server 2012. We should consider for backend Compatibility and level should be considered accordingly.


a) As it is the first Domain controller there is no option to check or uncheck . But for future ADC we need to check or uncheck these option as per need.


b) Kindly provide the DSRM password. It commonly known as passphrase earlier. Which is used while adding or removing any additional domain controller to have administrator authentication.

Note: Kindly note the password for future perspective.
