Child Domains in Active Directorry

By michaelh ·
My whole objective here is to have server1 as our accounting / file server, server2 as our CRM, and server3 as our internet-intranet and email server.
I'm also using a private IP address of 192.168.0.2 on the primary server and the other 2 are dynamically assigned, however I do have 3 public IP's for these servers as well for other purposes
I recently setup Active Directory on our Primary Server, we'll call xxx.com, I want to add my other 2 servers to the domain tree as x2.xxx.com and x3.xxx.com as child domains, however I'm not able to complete the entire process, I keep getting an alert that xxx.com either does not exist or can't be contacted. Do I have to do something about the DNS Forward/Reverse Lookups?

What am I missing? Michael.

You are missing the name of the parent domain. In a "Contiguous namespace", the name of the child object in an object hierarchy always contains the name of the parent domain.

Hi,

your problem sounds like one that I had in the past, and it was DNS related. You must ensure that the servers you wish to create the child domains on can contact the DNS entries that your original AD Domain Controller created. Check the IP based properties for these machines and check that they point to the same DNS Server as your original server. If this doesn't work then either your DNS server is offline, not enabled for Dynamic Updates, or enabled for secure dynamic updates.

To fixthis go to the DNS snap in on your DNS server, right click on your DNS zone and select properties. Ensure that Dynamic updates are selected, but turn off secure dynamic updates.

Thank
