Getting "the replication operation encountered a database error" when promoting a tree domain controller

Question

Hi
I am trying to promote a tree domain to an existing domain controller forrest but are getting this error. The event log shows event id 2140, 1173, 1168, 10000 and 1202. Can you advise?

Hello @LangeMuller ,

Thank you for posting here.

To better understand our issue, would you please confirm the following information at your convenience.
1-Is your AD environment a single forest with a domain or multiple domains before promoting a tree domain controller?
2-What is your forest functional level and domain functional level?
3-Which step did you encounter this error above? Please provide the screenshot if possible.
4-If it is a single forest with a domain with multiple DCs, or if it is a single forest with multiple domains, before we do any change in existing AD domain environment, we had better do:

1.Please run net share on all DCs to see if SYSVOL folder and NetLogon folder are shared.
2.Please run Dcdiag /v on all DCs to see if there is any error message.
3.Please run repadmin /showrepl and repadmin /replsum on PDC to check if AD replication works fine.
4.Please run gpupdate /force on all DCs to see if GPO can update successfully.

From the error message, it seems there is issue related to AD replication and DC database.

Should you have any question or concern, please feel free to let us know.

Best Regards,
