Hello @Cuong. Tao Minh - CTS TSD ,
I am sorry for the late reply.
Thank you for your update.
1.Did you logon the root domain DC and child domain DC with the same credential?
You can logon the root domain DC and child domain DC with the same credential (such as: root domain Administrator credential) to check if the issue persists.
2.And if you connect root DC and child DC through ADSI of root DC, and then check if the issue persists.
Should you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
