Run NETDOM QUERY FSMO to see the status.
If the Schema role is unavailable or associated with a system no longer available, you may need to seize it.
From a command prompt on the server run the following and confirm that the server knows where the FSMO role holder is:
netdom query FSMO
Verify that the server is configured correctly for DNS. If it's the only Domain Controller/DNS Server in the domain then it should be using itself for Primary DNS and using 127.0.0.1 for Secondary DNS.

While the question has already been answered by user @Tony, it is not clear enough about the actual reason:
One day someone turned on verbose logging of Kerberos events on the server.
And to disable it you should delete the following registry value:
Registry Value: LogLevel
As soon as you use Site to Zone Assignment List in a (computer) GPO: everything else is blocked including the built-in ones, and you cannot see the list.
I have to do some test to pinpoint exactly where this comes from but long story short: prefer using (user-side) Zone mapping GPO that is simply adding registry entries.

This crash occurs when trying to edit attributes of type "Numeric String" that are not "multi valued" with ADSI edit. Application verifier enabled for mmc.exe we can see a stack trace of this type of crash, it seems to crash on trying to delete an array of values:

To solve this issue, I had to consider several things:
IPv6 link local addressing is enabled regardless if we use IPv6 or not. So every server / host is going to have an IPv6 address and use IPv6 if it can.
Promoting a server to a Domain Controller w/DNS adds "localhost" as a DNS server on the local network interface for both IPv4 and IPv6. This ...
Leaving the default gateway blank is the best choice for two reasons
If there's a default gateway set, things will have to wait for a timeout whereas leaving it blank tells the OS there is "no route to host" and that will fail much quicker.
if some device ever gets that IP, it will start receiving unexpected traffic - probably ignoring it all but ...
For a DNS server's resolver, configure a different DNS server's IP address first, this DNS server's IP address second, and localhost IP third.
Even when the DNS service is restarting, it still can resolve from the remote server. Also when using AD DS, a different host first is less likely to cause replication problems.
Second, the server is preferring IPv6 ...
You can have multiple DC for a domain.
If you mean to do a migration your correct step should look that way;
I would add another step, 4.1, to test if the replication and all active directory is replicated correctly.
The part that is not wrote is that even if you have two domain named the same way, and account named the same in both, the GUID will not match,...
When KB5008102 (November 2021) is applied, this error will also occur if a user who is not in the "Domain Admins" global group tries to promote a domain controller. The update blocks the UAC settings up date with a message (on the DC you are replicating from/trying to update the computer object against):
The security account manager blocked a non-...
It really doesn't matter what you put as default gateway. All machines are in the same network thus no routing needs to happen so no gateway to another network needs to be contacted.
And yes, for DNS, if your server is hosting DNS and the other clients need it then the servers ip should be put into the clients' config as default DNS as you already ...
A Domain Controller is a server on the network that centrally manages access for users, PCs and servers on the network. It does this using Active Directory.
Active Directory is a database that organises your company’s users and computers. It provides authentication and authorization to applications, file services, printers, and other resources on the network....
When I ran into this issue it was specifically that I assumed I should quote the distinguished group name (since it contained spaces), however you specifically should not use quotes when it comes to Require ldap-group, see reference:
Once I removed the quotes I was able to use ldap-group ...
Right out of the docs:
[…] To modify an object property, you must use the LDAP display name. […]

Have you verified that you do not have a replication issue? (dcdiag /q)
Have you assigned the service account to AD computer object and installed it on the new server? If not, this could be a solution to your problem.
Run this with Domain Admin credentials:

Ugh, I keep meaning to write a blog post that corrects some of the poor formatting and phrasing in that article. And some of the other misconceptions I've seen elsewhere about configuring an NTP time source.
To cut to the chase - there are actually TWO GPOs you need to create. The first one is scoped to the PDCE with the WMI filter and the NTP time source ...
AGPM does much of that - it's a Microsoft tool that vendors like Microfocus leveraged off. It does all the versioning, check-in/check-out, approvals, roll-backs etc. It's not highly sophisicated, but it does the job.
The main drawback in a multi-...
Update: Using Windows Server 2016, I have no issue using a wildcard certificate for LDAPS. I am able to make a test connection using the ldp.exe utility on port 636 with "SSL" checked.
LDAPS works immediately after importing the wildcard cert into the Personal ("My") certificate store without any restart needed. I can confirm this is ...
This is default and expected behavior. You should avoid having the local admins burnt into image or provisioned with permanent static password.
Since you are in Hybrid mode, and according to best practices, please consider implementing LAPS (https://techcommunity.microsoft.com/t5/itops-talk-blog/step-by-step-guide-how-to-configure-microsoft-local/ba-p/...
You can rename a Win2008+ domain controller without major issues.
The preferred method is a three-steps netdom dance:
netdom computername <CurrentComputerName> /add:<NewComputerName>
netdom computername <CurrentComputerName> /makeprimary:<NewComputerName>
- reboot the DC -
netdom computername <NewComputerName> /remove:<...
No, you can't.
Some attributes are reserved and only the OS can manage them. Active Directory is not simply a user database, it also manages user authentication: you can't simply make some user account behave as it was someone else (SID / SID History), or fake user activities (such as last logon).
Also, there are no supported ways to manually edit the Active ...
The DC that holds the PDCe FSMO role is the authoritative time server for the domain. This is where the other DC's sync their time to. When you transfer the FSMO roles to SERVER3 you'll need to reconfigure the Windows Time service on SERVER3. Then when you move the FSMO roles back to the newly installed SERVER2 you'll need to reconfigure the Windows Time ...
