This article will tell you about registry keys that are responsible for whether your DCs use Dynamic DNS (Dynamic DNS) to register records on DNS servers or not.

Domain controllers register or update their DNS records on DNS servers every hour. He does this with DDNS (Dynamic DNS). Dynamic DNS must be enabled on the domain controller, after which they will be able to register their DNS records dynamically.

You can find out whether domain controllers use Dynamic DNS to register / update their records on the DNS server by viewing the following registry key:

Section Name: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Netlogon \ Parameter
Parameter Name: UseDynamicDns
Type: REG_DWORD
Value: 0 (disabled) 1 (enabled)
Always check the above option if domain controllers do not perform dynamic registration.
