Hi,

I need to setup a Windows DNS for our setup until the AD goes in.

I will have 2 servers 1 at each site.

The first site (site a) will have windows DNS and primary zones

The second site (site b) will have windows DNS and secondary zones read only
copy of the primary on site A's server

I want to enable dynamic DNS updates for my DHCP clients

Site a clients will point at site a server as primary and site b server as
secondary

site b clients will point at site b server primary and site a server
secondary.

My question is what happens when a site b client trys to initiate a dynamic
update?

Does the site b server send the client onto the state of authority or does
it refuse the update?

If it refuses the update does it then try the secondary DNS server specified
in DHCP assigned to the client?

Thanks!

Giorgio

are you having DHCP server do the DDNS registrations, or the clients
themselves?

The Client will look up the MNAME (Primary master on the SOA) record for the
zone it wants to register in, and send its update request to it.

Be aware, when you enable DDNS, I'd recommend using ADI zones over
Primary/Secondary zones. When a Primary is updated, it increments the zone
serial, causing the Secondary to request a zone transfers quite often
causing numerous zone transfer events on both the Primary and Secondary,
this leads to Run-time events on both servers and can fill the event log
quite rapidly. With ADI zones, there are no zone transfer events because the
zone data is replicated through Active Directory.
