Hello, Al. I am not getting the TTL angle. Since all he is changing is really the DNS servers and the clients's IP are not changing, I'd say bring up the new DNS server, copy the zone to the new server (secondary promoted to primary), reconfigure the DHCP scope to now hand out this new server as the DNS server, then restart dnsclient services on the clients or reboot them. Sincerely,

Kind of a belts and braces approach. I've typically done this by keeping both DNS servers online until I knew that all clients had been updated. Zone xfer works wonders. Once the clients are using the new server, give it until TTL has expired before sunsetting the original DNS server.

Is there anything else i should do to insure a smooth transition? should I lower the ttl for the zonejust incase clients have changed ip's via dhcp or anything else? thanks List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
