How to troubleshoot and fix Active Directory replication issues on Windows Server 2012 R2
Support NLB Solutions –
In this video I am going to show you an issue with my Active Directory replication between my two DCs and how I managed to resolve it. Tips and tricks for demoting a DC:
1. Always try graceful removal 1st, if you are not able to gracefully remove the DC proceed with Force Removal.
2. If you are performing a Forceful removal disconnect your DC in order to prevent corruption on your working DC.
3. Perform matadata cleanup from AD Users and Computers, DNS and AD Sites and Services when possible. If not you can proceed with ntdsutil /metadatacleanup.
