Q: After demotion, under the name servers tab, I still see the old 2003 dc listed as a dc under all DNS?
A: We can clean up server metadata by using several methods, please follow below link to force remove your demoted DC.

You can safely delete old 2003 dc entry from nameserver. Also it might be possible the OLD DC entries are still there in AD, DNS, sites and you need to perform metadata cleanup.

It seems the DNS configuration is not proper, to properly diagnose this problem, we'll need to see this information:
1. Ipconfig /all from your DCs (unedited).
2. List of forward lookup zones in your local DNS server.
ipconfig /all should have a Primary DNS suffix that matches exactly your Active Directory Domain name, and your Forward Lookup zone in DNS. DNS should also have one additional Forward Lookup zone named _msdcs..
Most important thing is DC should point itself as a primary DNS and another DC as secondary in NIC. Do not add public DNS IP in NIC. open cmd> run "ipconfig /flushdns & ipconfig /registerdns", restart DNS and NETLOGON service.
First of all, I’d like to explain that if there are errors in the System log viewer, DCDiag will detect those errors and report a failure for the Systemlog test. Once we clear the System logs, the systemlog test will work properly. Please try this, to see if helped. In addition, please also let me know if you have any other errors when running DCDiag command.
Please reference the following article and thread link to fix your problem:

the old domain controllers have been deleted? if so it looks like you may have some metadata left for them, you should go through and clean out all your DNS entries for DC's that no longer exist and make sure no metadata remains.

First of all is this the only domain controller having this issue or do all domain controllers show this error?
The test checks the to make sure that for each NS record there is a corresponding glue record .

Thank you for reply.
Yes, I have checked on several DCs - the same results.
I have the next structure of Forward Lookup zone:
Is there something in structure of forward lookup zone wrong?
Should I have glue records for all dcs in domain? Or maybe only for external trasting domains?
Inside I see NS records of current and old domain controllers of my domain.
Will it cause problems?

Can you run the following command where you replace with the actual name of the DC you performed DCDIAG on, and post back the results.
Sorry for long delay - I have tried to find and delete all old domain controllers in all DNS. No result. Still have broken delegated domain errors (see above).
The result of the command dnscmd/EnumZones is:

Give this a read about metadata cleanup.
OP StandingForChildren
The server is not available to be deleted via any of these methods, it's just hanging around in DNS delegation somewhere
M Boyle
The Metadata cleanup is run on an existing DC.
You're looking for any remnants of the old server that are hanging around in AD and deleting them.
OP StandingForChildren
I was running the tests on a DC - can't find sing ADSIEdit either.
OP StandingForChildren
OK, found the record tucked into the greyed out _msdcs folder in MYDOMAIN.LAN
Removed reference to old name server and tests now pass bar one warning

Secure way of transferring files
Hi all,I have 2 separate networks (separate DCs) that I need to be able to securely transfer files to and from, we currently have a Windows FTP set up to allow us to do this, which everyone has access to everyone's folder (as users need to be able to drop.
We have one server running Windows Server 2012 R2 which is the DC in our Windows Domain. Up until this past week everything has been running fine.
I noticed the issue upon trying to setup a new workstation using WDS. The OS installation was fine but after the deployment completed I noticed none of our software was on the deployed machine. (I deploy all of our software over GPO). Upon further inspection I found none of our workstations are able to update group policy succsesfully.
At this point I believe I've pinpointed this to be an issue within DNS. Regardless if there is something else broken, I'm pretty certain DNS needs to be fixed first.
I am attaching a DCDIAG /test:DNS for review. I would greatly appreciate if something would help me fix the broken delegation. I tried attaching a text document with the results but it would not let me, so I am pasting below.

If you use the Code box for the output of DCDiag it makes it a lot easier to read.
As for your errors, it is saying you have multiple interfaces configured. Is this DC multi-homed? It is also saying that you are getting an IP dynamically for this DC.
Do you have multiple DCs?
If you do your DNS settings should be
Primary DNS: IP of other DC
Secondary DNS: IP of local DC or localhost.
Can you post the output of the following command?

Here are some items you need to address.
I've found that if you use a loopback address, (127.0.0.1) as a dns server in your NIC Properties, AD Does not like this. Utilize the exact IP address of the server itself, in your case 192.168.1.254. That IP Address in particular, it normally refers to a Firewall or Internet Gateway. I'd change that to a number between 192.168.1.1-10 unless your Firewall or Internet Gateway is on 192.168.1.1 For the servers Alternate DNS Server, use your backup Domain Controller. Make sure that on the DNS Tab of your NIC, that you have the proper radios and checkboxes selected. The Local Server is at the top and the backup DC is at the bottom. Specifically Register this connections addresses in DNS. If you fix that, the error regarding your PTR Records will clear up too which is on the loopback address. It also should clear up your other errors.
This is the only DC within the domain. I'm hoping to add another in the near future for redundancy.
I have a static entry set for the server on our Sonic Wall, which is our DHCP server. I can't recall why, but I remember there was some type of issue when I tried setting static IP settings on the server itself.
Primary DNS: 192.168.1.254
Secondary DNS: 127.0.0.1
The DNS server is not open to public - only internal resolution.
I've already double checked the interface settings and they are set according to recommended best practices.
DNS is set to to serve using only the ipv4 address (192.168.1.254)
Here's the output from dcdiag /v /c /e /q
The addresses in the events are the IP addresses I have configured within DNS - forwarders. - See attached. es in the events are the IP addresses I have configured within DNS - forwarders. - See attached.
Also , the server fails NS resolution. I think this is part of whatever is broken. Please see attached.

I have double checked the configuration and I have allow the appropriates boxes checked and settings configured as depicted in your post.

Your forwarders are fine. You can ignore those errors. That is just Windows being stupid trying to talk to non-windows DNS servers with Windows protocols.
When is the last time this server was restarted? Can you do lookups against it.Nslookup 192.168.1.254
Verify your SRV records
You can also try on the DC.
Also if your Firewall is doing DHCP make sure it is handing out option 15 with your domain name.
Also check to see that your firewall is running the correct profile.

DNS services are all running? How about in the event viewer, any DNS events, or others of interest?
Only use one NIC on a DC, statically assign the network configuration to it and disable the other one.
Also in the future, when you have a 2nd DC, make sure their primary DNS are set to eachother, then secondary to themselves. Common configuration mistake!
Jason7658
Community Testing in progress on the Spiceworks Servers was giving me some problems giving you a response. If it were me, I'd have your Domain Controller handling your DHCP. If you are having the Sonicwall/Firewall passout IP Addresses, dynamic registration is not taking place. This means that when a DHCP lease it up, the Sonicwall/Firewall does not have permission to re-register those DNS names on the DNS Server. What is the IP address for the firewall?
One quick way to get another Domain Controller up to help for redundancy would be to make your current DC a Hyper-V host. Legally, if you are running Windows 2012 R2 server Standard, you can have up to 1 host and 1 VM use the same license. It's generally best to have Microsoft run the core network services like DNS and DHCP. That way you can control how DNS entries are handled through DHCP which can server as a Proxy for updates. It helps keep stale entries out of both. Also by using the DC as the DHCP server, you can use AD Secure DNS entries. Take a look at this- You have to remember, non Microsoft nodes cannot utilize dynamic DNS. A DHCP Server as a Proxy can.
Also if your Firewall is doing DHCP make sure it is handing out option 15 with your domain name.
Also check to see that your firewall is running the correct profile.
Our Firewall is not handing out option 15 but I am hesitant to change that at the moment without first resolving the issues at hand. I have never had that option enabled and things have been working fine for almost two years.
Here is the output from nslookup on the DNS server itself and then one from a client. As you can see, the server itself fails but resolution seems fine on the clients.
I think I am missing some reverse lookup records.
Justin1250
Are you running Windows firewall on that box?
It looks like your reverse zone is there. Your PTR records would be there but pointer records should not cause what you are experiencing.

What records do you have in your reverse lookup zone? Is there a PTR record in there for your DC.

1> Looks you have multiple adapters and DHCP Ip configured on DC, nslookup will not resolve unless a reverse-zone + PTR is not created and IPv6 unchecked
There is a PTR record but am not certain if it's correct.
What confuses me is the _msdcs zone under our domain, and then there is the _msdcs.domain zone as well.

JitenSh wrote:

also check
My understanding is that best practice is to use a static IP address to avoid a situation in which the system is assigned some random IP address from the DHCP server when the client machines are looking for a specific address. I just do not think this is a concern due to the fact that the server has the correct IP address it is supposed to have and that client machines look to.
Is may be a violation of recommended configuration best practices - yes. Is it impacting the current situation? I do not think so.
Unless there are other reasons I am not aware of there is no point to continue discussion about the server being assigned an IP address over DHCP.

We only have one DC in the domain - it is also the server running DNS. When I restarted the netlogon service I see Event ID 5781.

JitenSh wrote:

I have tried running nltest.exe /dsregdns to no avail.
Are you talking about turning off ipv6 for the NIC? I already have ipv6 disabled for DNS, so it is only listening for DNS requests on the ipv4 address.

I demoted my last 2008 R2 domain controller, DC-01, a few hours ago. Everything went fine with that, the two new 2012 R2 domain controllers (DC-1 and DC-2) have been running for a few weeks. Replication tool reports no errors, a plain dcdiag is happy too. However, I've found that dcdiag /test:dns is showing this:
It's been a while since I dealt with demoting a DC - what'd I miss?

I know if I opened the properties of the NS record, there was an option to add name servers, though I did not try it. I guess I was curious why everything else removed DC-01 correctly, but not this. I also got myself a bit confused when searching about it since there seemed to be some references to deleting and creating a new delegation. On the upside everything seems to be working.
Will check the PTR records in the morning, thanks.
PTR looks good, there are the two NS records there as expected. There is a PTR for the old DC as well but not NS.
I came across this thread, which had a ton of great information:
And ultimately, I did add the new DC to the list and removed the old one. Every test I've done now is passing. Still not sure why that would be the only thing that didn't happen automatically, but oh well.
