Start by checking your DNS setup on the NICs of your domain controllers. The vast majority of replication issues are caused by misconfigured DNS. Verify that first and we can go from there.<\/p>\n\n \n

You should never manipulate sysvol or any folders in DCs as they are automatically created and managed by DCs<\/p>\n

Check your DNS IP addresses in all the DCs ?

AD1 WAS replicating at one point, but is no longer replicating.<\/p>\n
All domain controllers have migrated successfully to the Global state (‘Eliminated’).<\/p>\n
