URGENT - I can't connect to domain inside domain controller
Hi all,
I am facing a strange problem inside an active directory server (domain controller - Windows Server 2012 R2), when I open "dsa.msc" and I receive a message, can't connect to domain.
Please, I need help. URGENT

What is the exact error message you're seeing?
A couple of suggestions: Verify the DNS settings on the NIC. Verify that DNS service is started.

So. The DNS is OK, running. The both domain controllers show this message. The network settings is ok.
The BPA show that AD is OK too. Help, I have 300 users stoped.

So, I can't connect to Users and Computers snap-in. Computers on network can't connect to domain. I've checked DNS settings and all are fine.
So, I can't connect to domain, If I go to domain controller and put DNS to 127.0.0.1, the server still continue showing message, domain couldn't be contacted.
Any suggestion?

Any suggestion?
Check the Windows firewall settings on the domain controller, set it to disabled. Make sure the network cable is connected. Make sure you can ping the default gateway, and any other machines on your network.

I did this. The issue persist.
On a client machine, run a command prompt and then run nslookup.
Enter the following commands:
server <ip address of your domain controller>
<hostname of your domain controller>
Does the address resolve correctly?
Next try to resolve this address (replace "example.local" with your active directory domain name):
_ldap._tcp.dc._msdcs.examp

server <ip address of your domain controller>
<hostname of your domain controller>

Next try to resolve this address (replace "example.local" with your active directory domain name):

Run the following commands on the DC
repadmin /replsum
repadmin /showrepl
repadmin /bridgeheads
DCDiag /v
Netdom query DC
Netdom Query FSMO
Also check your Directory Service Logs on this DC.
Make sure that the Netlogon Service is started and that the Active Directory Service is also start.

Asavener,
I tried your sugestion and the machine resolves name correctly.
Will,
Netlogon is running too, I tried to restart service, but same issue. The replication doesn't work.

Verify that the time is synchronized between the servers.

I solved the problem but the suggestions from experts didn't make effect.
Did you try to right click and select Change Domain Controller...?
