Dynamic Update question
ACE-Joe
servers, accept dynamic updates?
Scenario: Main hub office with two dns servers (pre-Active Directory)
three other hub offices in geographically separate locations, each with two
dns servers setup as secondary DNS Servers.
Clients configured for their secondary (Secondary) DNS server as the primary
(preferred DNS Server) in their IP configuration. In this scenario will
dynamic updates work for client DNS? Or will they all need to be pointed to
the first dns server in the main hub office thats setup as the primary?
Also, can you have more than one primary DNS server in this scenario? We
are migrating to AD, but in stages, DNS first, then AD, then Exchange. So
whats the best way to setup internal DNS?
Thanks

Well, what happens is the client will ferret the MNAME record from the
secondary zone so it can send it to the server holding the writable zone.
Then zone transfer occurs and the secondary will be updated with the new
data.

No, the secondary is fine. But keep in mind, if the WAN link goes down,
nothing will get registered.

NO. Following based on the RFCs. there can be only one (sounds like the
"Highlander" TV show).

Once you've gone to AD, and install DNS on the DCs, then you can use AD
Integrated zones and all DCs will automatcially have a copy. No need for
secondaries.

(How to configure a forwarder):
Also: Recommendation - Point all machines only to the internal servers, and
configure a forwarder to your ISP's DNS. This way all machines query your
DNS and if it doesn;'t have the answer, it asks outside. If the forwarding
option is grayed out, delete the root zone, (it looks like a period),
refresh the console, and try again. If not sure how to configure this, this
