Primary and Secondary DNS
Posted on 2006-11-06
In in a windows environment, I have heard that once the primary DNS server becomes unavailable, the client will use the secondary DNS server for resolution, and will continue to use the secondary DNS server until IT becomes unavailable. This of course would cause havoc on networks setup by techs who use an external dns server as a secondary in an active directory enviroment.
I'm looking for a microsoft article that confirms the primary is no longer polled until the secondary becomes unavailable, or the workstation is rebooted.
