Hello,
I tried to find an object to which error message refers (CN=Domain System Volume (SYSVOL share) in ADSI, but there is no such an object, there is only object 'CN=File Replication Service,CN=System,DC=domain,DC=com' without any child objects
This is normal.
Ensure you are running with the right permissions, Domain Admin, EA...
Determine if the existing domain controller has inconsistent objects (https://video2.skills-academy.com/en-us/previous-versions/windows/it-pro/windows-server-2003/cc785298(v=ws.10)?redirectedfrom=MSDN).
Check if you need to perform a metadata cleanup (https://video2.skills-academy.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc816907(v=ws.10))
Check to make sure SYSVOL is shared, check the next value, if not set it to 1.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\parameters
Value SysvolReady
= 1
Please check what is the migration state using:
Dfsrmig /getmigrationstate
Also check to see if the you get any errors with this command:
Dcdiag /e /test:sysvolcheck /test:advertising
