Problem Installing Active Directory on Windows Server 2008

Hi,

I'm learning on how to install and run Windows Server 2008 in a non production environment to make sure I understand how to configure it. This is a brand new environment – there are no other AD or DNS servers. I'm running the AD DS wizard (I have not installed DNS on this server yet – it mentioned it would set up DNS during the AD DS setup – should I have set it up first?)

A delegation for this DNS server cannot be created because the authoritative parent zone cannot be found or it does not run Windows DNS server. If you are integrating with an existing DNS infrastructure, you should manually create a delegation to this DNS server in the parent zone to ensure reliable name resolution from outside the domain mydomain.local. Otherwise, no action is required.

Do you want to continue?

My new domain is abc.lan. During the add wizard process it is examining the DNS configuration and comes back with this message – A delegation for this DNS server cannot be created because the authoritative parent zone cannot be found or it does not run Windows DNS server. If you are integrating with an existing DNS infrastructure, you should manually create a delegation to this DNS server in the parent zone to ensure reliable name resolution from outside the domain abc.lan. Otherwise, no action is required. I saw some people posts that I should ignore this, but I wanted to make sure. Please help.

Thanks.

  • This is quite common and known issue please go through the fallowing link for more detail.
  • The error occurs when: 
  • The Active Directory Domain Services Installation Wizard (Dcpromo.exe) has been configured to install the DNS server role.
  • Enough delegations do not already exist between DNS servers in the immediate parent DNS zone and the subdomain where you are installing the new domain controller.
  • The domain controller you are installing is unable to create a delegation to the DNS subdomain on a DNS server that is authoritative for the parent zone. 
  • Dcpromo.exe tries to create the delegation to ensure that computers in other domains can resolve DNS queries for hosts, including domain controllers and member computers, in the DNS subdomain.
  • Dcpromo.exe can auto-create such delegations only on Microsoft DNS servers and will always fail if the parent DNS domain zone resides on third party DNS servers such as BIND.

Once you have installed the server 2008 then the first thing you need to do is to make it a part of some domain on make a domain on it you can use DCPROMO for this purpose. And after you have a domain as you mention in your problem then you need to install the DNS first and then you can configure it also. As if you have a domain as abc.lan and now you want to add a DNS then you can first install it and then you can implement it. If you have already setup a DNS then try to remove it and make a new copy for that and it will not happen manually but you need to configure it your self to do this first go to add remove components and then install the DNS from there if it is already installed then well and good now once you have installed DNS then you can configure it manually as per your requirements.
