Changes

*To set up the domain controller we need to add a new role to the server- 'AD DS role' Go to Server Dashboard-> Add roles and features. A window will pop up asking to add roles and features. In the installation type tab select role based installation. Select the server in the next tab. In the next tab there will be a list of roles that one can add. For this installation we need Active Directory Domain Services(AD DS). After selecting AD DS it will pop-up to add other AD DS related tools. Click on Add Features. In the features we do not need additional features than those that are selected default. Click Next->next->Install. (machine may restart)

*Once the installation of AD DS role is done, there will be a notification on the server dashboard to promote this machine to a domain controller. Click on that option. A window will pop to set up the Domain controller. In the deployment configuration tab select create a new forest as this a completely new domain. Give it a name, in our case it is 'ad.mcnaircenter.org' . In the next tab set up a password for the DSRM. I gave the same password as the machine. there will a DNS warning click on next. It will suggest a NETBIOS name AD0 in our case click next . If all the prerequisites are checked click on Install.
