In need to migrate my Domain Controller to Windows 2003 R2 to Windows 2008 R2 I followed the nice tutorial, written by TigerMatt: http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Windows_Server_2008/Q_23582347.html # a22052091

I did everything step-by-step, no hurry, however when I disabled the old DC to verify that the new dc was functional, the AD did not rise. and the following message appears:

Naming information cannot be Located because...

Then I click OK and the AD is empty.
Then I click change domain controller, Active Directory users and computers and the same is empty, do not seem to be connected anywhere, when what I expected, is that he was the Operations Master, and Domain controller after all the main steps followed in the aforementioned tutorial.

Some have a clue?

Can you confirm ( please check - dont answer without checking) that you did the global catalogue and FSMO role migration from the old DC ?

Can you also check that you did the DNS section of the guide ?

it looks like at the very least that the DNS server either isnt available, or doesnt have any SRV records...

Can you use DNS manager, and connect to the new server and show is the forward and reverse zone information?

specifically that it has

Forward Lookup Zones/Domain_Name/_msdcs/dc/_sites/Default-First-Site-Name/_tcp
Forward Lookup Zones/Domain_Name/_msdcs/dc/_tcp

better still, follow the guides here http://support.microsoft.com/kb/816587 and verify that your DNS server (should be AD integrated) is working. If it is, then we can look at the FSMO role stuff, if its not then potentially either the DNS hasnt moved correctly, or you have missed a step.

I think I got it!
I checked the new DC, the PDC and Infrastructure were still with the old server as a master of operations.
So I went in the old server, Operations Master and changed pointing to the new server.
deactivated the old DC and went to the new dc. In the new DC, when I opened the AD found that he was still "empty", clicked change Domain controller and found that they had to appear in the list the DC's assets was written: Type the directory server name. I typed the name of the new DC and it connected!

Want to know what was the problem? Too lazy to read. LOL

Thanks for the support

Yep - though as much. For problems as you describe its also a FSMO placement, or a DNS issue. Glad i could help.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Here is the first problem you should never just shutdown a DC.

First thing check your DNS settings on the servers they should be pointing to themselves as primary in TCP\IP settings for DNS. There should be no external DNS servers listed.

Make sure your new DC is a Global Catalog. Make sure the new DC holds on FSMO roles.

Run dcdiag post results.

I thought the problem was "PDC and Infrastructure master" still on the old server, if so, i mentioned that as my first post ? why close, rather than award points ?
