Preparing DNS for AD Domain Rename
So I am currently gathering information in regards to renaming our AD domain name from company.net to company.local.
I am reading through the docs on technet.microsoft.com and It states that I would need to prepare the new DNS zones before executing the domain rename.
The question I am asking about is regarding the _msdcs subdomain
_msdcs.company.net
I have read posts of forums where people reported issues after renaming their domain and not having the _msdcs subdomain forward lookup zone. Some even reported that an _msdcs subdomain is created but inside
Obvisouly _msdcs is needed So should I create two forward lookup zones like so;
_msdcs.company.local company.local
When the domain name rename has been executed and the DC are restarting will they auto generate all the relevent _msdcs records in the new forward lookup zone _msdcs.company.local or will I have to create them myself.
Many thanks.
Solution 1:
First of all, please read my blog post about how to name your AD.
Ok, so now you're hopefully ready to name your AD ad.example.com
or corp.example.com
. Good choice, that's very reasonable of you.
To answer your actual question, after you complete the domain rename and reboot the DCs, they will self-register everything necessary in the _msdcs zone.
A word of warning, do this in a test lab two or three times first. You only get one shot, don't screw it up!
