We have this setup:
one server with Windows Server 2012 and Hyper-V that runs 2 WServer 2012 VM's, one of them is the primary domain controller which is working fine and other that runs SAP
one physical server that we use for other system, and as a secondary domain controller, which is NOT working well since the domain's administrator account password was changed.
The issue is that when we connect remotely to the secondary domain controller, it still accepts the old password, and not the new one. It also has an outdated version of AD users and and old version of the DNS server, it is like it has stopped updating itself from the primary domain controller.
This change was made by an old employee and he did not document it, so I don't really know what procedure he followed.
How can I make it updating again from the primary DC?
