If I go for DNS-ADI, should I specify the DNS prim=DNScentral site

[Marlon Brown]

I have 10 branch offices and if I setup AD-DNS Integrated, I understand each
DC would hold a copy of DNS zones.

In that circumstance, should I point thousands of windows clients IP address
t as IP DNS Primary=DNSCentral Site ?
How clients would take advantage of multimaster and DNS-DC redundancy in
case the primary DNS goes down ??!!

Well, each DC on which you choose to run DNS server,
although that might be all of them it is not a rule.

??? You should generally point each client to the 'nearest'
(several) DNS servers -- they MUST be pointed strictly
to your internal DNS servers.

Part of the point of AD-Integrated is multi-mastered
registration -- clients can register AND resolve addresses
with ANY such DNS server.

How clients would take advantage of multimaster and DNS-DC redundancy in
case the primary DNS goes down ??!!

Since each DC (running DNS) is a DC, that IS the
basis of multi-mastering and it will replicate as
part of AD, efficiently and as described by your
in Sites and Services (Sites, Site Links with Schedules,
Costs, and Frequency.)

Thanks Herb.
That means that I need to change the settings for each of the subnets DHCP
server provides IP configuration to (since DHCP the device giving out IP
configuration information to clients).

Yes, each DHCP server should set the first (primary) DNS server option as the
local one. But also add the main site (or the closest physical site if it's
not the main site) DNS server as well.

All (DNS) clients should use multiple DNS servers for redundency.

Well, each DC on which you choose to run DNS server, although that might be all of them it is not a rule.

I'll elaborate on this too, if Herb doesn't mind [yikes!]

Each DC will hold the actual zone data (it's replicated as part of the
domain partition or, in 2003, it can be replicated as its own application
partition) but not necessarilly function as a DNS server with that data.

Obviously this statement only applies to DCs within the scope of the
partition.
