Hello There,

Sorry i'm newbie on managing windows Actove Directory.
We have single AD DC on winserv 2019 with hostname DC1 then we want to make redundancy/fault tolerant to this domain, so we create secondary Domain Controller (DC2) to achieve this goal.
I follow video tutorial on Adding Additional Domain Controller on this youtube video (link)

But, unfortunately after promoting secondary server to a domain controller finished, i checked the DNS Server there is empty/no DNS record on this DC2, not same with the video tutorial.

When i run command repadmin /showrepl, it's show successfully replicate. but
When i run command repadmin /syncall, it's show error like this

"C:\>repadmin /syncall
CALLBACK MESSAGE: Error contacting server <object guid of NTDS
Settings object>._msdcs.<forest root domain>.<top level domain>
(network error): 1722 (0x6ba):
The RPC server is unavailable."

How to properly solved this problem.
I know maybe this fault came from DNS issue, since there is no/empty record on second DC, but how to fix this problem properly?

Thanks, hopefully anyone who can help my problem.
