asked on

The specified domain either does not exist or could not be contacted" error message in Windows Server 2012

Hello,

My Current environment: We are having two windows servers 2012 (DC01 and DC02) acting as Domain controller and GC. One server is hosted on ESX01 and Second server is hosted on ESX02.

DC01 is Primary domain controller and hold all FSMO roles.

Veeam backup is used for backing up DC01 and We don't take backup of DC02.

Now, in my vCenter: I created a Test environment by configuring new vswitch so it will not touch production environment. I tried to restore DC01 from veeam backup on new Test Environment. Retore from Veeam was successfull on different location for Test.

But when I start my server (DC01-Restored) and try to start Active directory users and computers i got following error:

Naming information cannot be located because: The specified domain either does not exist or could not be contacted. contact your administrator to verify that your doamin is properly configured and is currently online.

Any suggestions?

Thx

Hi Sumitgupta85,

It seems in your case it cannot find AD DNS.
I would check the services that all services that are on automatic are started, and all dependecies are running.

Adding to my previous comment, it might also be your SYSVOL and NETLOGON shares are not available.
Please try to type in the addressbar of Windows Explorer: \\servername\SYSVOL\

Maybe to troubleshoot further, please post the output of DCDIAG

DNS is properly resolving names and all services are running fine.
Yes, on server SYSVOL and NETLOGON shares are not available. I can give you screenshots of Dcdiag command but i'm sorry it will be in french language. So shall I put screenshots?
What is primary DNS set on the server. Is it set to its own IP address or 127.0.0.1

Set it to its own IP address.
Yes its already 127.0.0.1. All the settings are same from running DC as its just a restored version.
@BM-vnext DCdiag Logs are attached in English. you can review them

Registry editing suggested by microsoft article solved problem. Use of Dcdiag to search errors on google.
