Active Directory not functioning

I cannot use AD Management tools.  When I try to run AD Users and Computers, I get
Server is running Windows Server 2012 and I do not have a good backup of AD.

DCDIAG output shows error 1355 that it cannot contact the GC.

Here is the output of a couple of NLTEST commands:

nltest /DSGETDC:seward.local
Getting DC name failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN
The command completed successfully

nltest /DSGETDC:seward.local /PDC

In addition, the NIC is stuck on the Public firewall profile.  I've tried putting Letwork Location Awareness on Automatic Delayed start, but it still won't come up as a domain for the firewall profile.  I've tried turning the firewall completely off, but still get the same responses as above.

What is your primary DNS server?

DNS Server is set to the IP of the DC.

Install rsat on a workstation. To remotely manage the AD in the event the access is impacted by profike corruption.


nslookup -q=SRV _ldap._tcp.dc._msdcs.youraddomain.local

Make sure the system dies jot have external public servers.

Check the event log for errors, indications what might be going.

It seems you have a problem with DNS. try using the IP with your AD management tool. does it work?
Check if DNS is up and running.
how many DCs have you got? are you trying AD management froma client or from DC itself?

Yes, the domain controller responds to ping over IPv4 and IPv6.  Looks like I may have a mismatch on the IPv6 address in my DNS server.  Is there an easy way to properly update the IPv6 records in DNS?

arnoldCommented:
Ipconfig /registerdns. Or something like that.

Do you actually assign IPv6 IPs through dhcp?t

Server ip, static? Add directly in the DNS interface aaaa record.

It's only a six station network.  Thanks for the suggestions, but I'm going to cut my losses on time here and just create a new AD and migrate the users to it.  I have tools to reassign their old profiles in the new domain and I think that's going to be my path of least resistance here.  I simply can't find the reason AD won't resolve and I don't have anymore time to chase it.
