A new domain controller has been added to your domain.

When a new domain controller is added to a domain, it is necessary to update the CyberArk infrastructure to ensure it can use the new domain controller for authentication. This involves updating the hosts file on the Vault server located at Windows\System32\Etc\Hosts to include the new domain controller’s details. Additionally, within the PVWA Application, you need to navigate to Administration > LDAP Integration > Directories > Hosts and update the information there as well. This ensures that both the Vault server and the PVWA Application are aware of the new domain controller and can authenticate against it1.
