<\/a><\/p>\nFor some reason, I got the following message regarding my IP address assignment. I only had one NIC, and while the interface was using DHCP, I configured the interface with a static address before I started this process.<\/p>\n
I am getting caught up on some old notes I had not finished up. The following is the procedure I used to add a second domain controller and DNS to an existing domain with one domain controller and one DNS. This environment was all Windows 2008. I am not sure whether it was R2 or not, but I the procedure should be very similar for either version.<\/p>\n
From the newly created member server:<\/p>\n
Go to “Server Manager” and click on “Roles.”<\/p>\n
Click on “Add Roles.”<\/p>\n
Select “Active Directory Domain Services.” This will install the domain services. Since this is a second domain controller being added, you will not be asked to install a DNS server like you would if it was the first domain controller in the domain.<\/p>\n
Once completed, you need to run dcpromo.exe to make your server an active server as an active domain controller in your domain. I chose to “Use advanced mode installation.”<\/p>\n
You will need to choose your deployment configuration (Existing forest or new domain in a new forest). Click “Existing forest” and “Add a domain controller to an existing domain.”<\/p>\n
Enter the name of the domain. Note: this will already be populated correctly, if you had previously joined the domain as a server.<\/p>\n
Under “Alternate credentials”, click “Set…” and enter Administrator level account credentials for the domain and click “Next.”<\/p>\n
Under “Additional Domain Controller Options”, I unchecked “Global catalog” but left “DNS server” checked because I wanted to add another DNS to the domain. I did not want a “Read-only domain controller (RODC).” <\/p>\n
If you receive the following message, you need to choose appropriately. I decided to “Transfer the infrastructure master role to this domain controller.”<\/p>\n
