Promoting a domain controller in a site that does not see the master RID

The company I am working for has multiple sites in China, US and NL. Because there are problems establishing site-to-site connections with CN, we only have one MPLS connection between CN and US ant a site-to-site VPN between US and NL. The master domain controller was installed in CN and I created another one in US without problems. Now I am trying to set one in NL. The NL site is not seeing the CN site, so it is not seeing the RID master. When I try to promote the server in NL as a DC it is failing for this reason.
Is there anything I can do to bypass this issue?
All the the servers are 2019.
Thanks,
Mugurel

AFAIK, the domain controller need to contact the RID Master to receive the RID Pool.

If the DC is not able to contact the RID Master, it will never work.

Might check the logs for details

  • %systemroot%\debug\dcpromo.log

  • Event viewer\Windows logs\System

  • Event viewer\Windows logs\Application

  • Event viewer\Applications and services logs\Directory Service

  • Event viewer\Applications and services logs\File Replication Service

  • Event viewer\Applications and services logs\DFS Replication

I was afraid that is the case, just trying to see if there is any workaround. With the current setup, the RID Master is not going to be visible in NL :-(

Thanks
