Issue adding second domain controller.

[ChipStone]

I found a previous thread from CatCheeto that is a duplicate of my issue (but with no resolution) so pardon me if I plagerise.
I have an AD Domain with one server and apx 180 workstations. I've built a new box that I want to add as an additional DC.

I type DCpromo, select Additional. Type in my user, pass, and full DNS (domain.biz lets say) It says that it cannot gain access to the list of domains in the forest anf that the specified domain either doesn't exist or could not be contacted. 2 things that are weird to me, I am logged onto the domain and the 2nd it filled in the domain name for me. So, I try just typing in "domain" without the .biz and it works. It then asks for the domain I wish to join and it has Domain.biz and it pop's up with "Domain cannot be contacted. Ensure DNS domain name is type properly. So I try server.domain.biz thinking it needs a computer on the domain. That doesn't work. Then I go with just "domain" and it tells me that the domain name "domain" refers to "Domain.biz, and is that what I intended. I hit yes. It ask where I wan't everything stored and I do the defaults, enter the defualt password for restore mode. It starts to try to transfer files and says "op failed. Failed finding a suitable DC for the domain domain.biz. It either doesn't exist or couldn't be contacted"

I've checked DNS and the Forward Lookup appears correct. Do I need to add anything to the Reverse Lookup?

I've run NSLOOKUP from both servers (both are in the domain, however, the new one won't promote) and receive the following:Can't find server name for address xxx.xxx.xxx.xxx. Non-existent domain....

So, sorry for the long drawn out, but I wanted to give as much info as I could. I could ping the server, and the server could ping the new DC. I have domain admin rights with the user I am typing in and the user I am logged on to. Would any other info be helpful?

It initially sounds like the server you are trying to promote is not using a DNS server that is AD integrated into your Domain. So my initial step would be confirming that it is.

Will I need to rebuild DNS completely if it isn't?

Thank you for you assistance!

One thing you need to do before you run dcpromo is to make sure you set "Allow dynamic Updates" to "Yes" in the properties of your forward and reverse lookup zone.

Did you get DNS working before you ran dcpromo? It is recommended because if DNS isn't working correctly you will never get AD to work properly.

I found a TID from MS that walked through a complete rebuild of DNS for AD. Followed the procedure on the working DC and then attempted the add the second DC. Everything went smoothly! Still don't know the true source of the problem other than DNS wasn't functioning properly on the DC>

Thank you DVNT1 and MEESE for your input.

DVNT1, I'm glad you don't sleep

Glad you got it to work ChipStone!

Chipstone,

Can you post the TID from MS that you followed?

Chipstone,

I to would like a link to the TID from MS.

Congrats on getting you second DC up and running!!
