How does DNS resolve hostnames during a forest down? -
Beschreibung
In the case of a forest down, where all DNS servers are unreachable, how does the RMAD Forest Recovery console resolve hostnames? -
Lösung
Hostnames are cached at two points when configuring the project.
1. During a full "Verify Settings" of the project, hostnames and IP addresses are cached and stored for later use.
2. In Forest Recovery console, go to Tools > Manage > DNS Client Settings
This will also collect and cache the IPs and hostnamesIf all configured DNS servers are unreachable when a restore is initiated, the stored IP addresses are used for restore procedures instead.
Either Verify Settings, or going into the DNS Client Settings should be done at regular intervals, especially if the DC IPs may regularly change.
