Question: AD DNS vs Primary/Secondary

[SteveC]

Hello,

What pros and cons are associated with running an AD DNS versus the
traditional primary / secondary DNS?

Does AD DNS replicate faster? Faster zone transfer?

Does AD DNS replication use less bandwith? Zone transfer use less
bandwidth?

Is the registration of SRV records quicker?

Is DC location slower with traditional DNS?

On WinXP, if I change my AD domain, does my DNS zone domain switch over as
well?

Is DC registration and record replication quicker?

On a traditional DNS system, if a DC Secondary DNS ServerB boots up in
Europe, does it register with DC Primary DNS ServerA located in the US.
ServerA would then push the updated records to ServerB?

Is this one of those questions that best answered specific to each network?
A dual server network with a single DNS domain would use one implemenation,
while an enterprise network with 1 parent domain and 25 child domains would
use another?

The differences between AD and primary/secondary seem trivial. Maybe I'm
missing something.

While I'm on the subject, is there any danger in switching an AD DNS to
Primary DNS? An AD DNS to Secondary?
Will it affect workstation logins, DC registrations, AD replication?

Can a AD DNS and traditional DNS for the SAME zone co-exist? Some servers
use traditional, others use AD?
This would mean more work to keep records in synch, but is it doable?

Hopefully, I posted some thought provoking questions. Or maybe I'm just
asking something silly.

SteveC

DNS zone info replicates as normal AD data during AD replications (i.e. its
just some more elements to replicate.) Those replications are optimized and
scheduled. So if you have AD and std XFR, you still have to do AD
replication *and do XFR or IXFR so your running two different replication
topologies. So you don't save anything with std zones ontop of DCs, but you
do gain AD's replication topology and the use of multi-master zones with
ad-integrated zones (which helps with DRA and speed of host updates).

Thanks so much for the insight.

In a AD DNS with several DNS servers, can I safely change 1 server to
primary, perform a file copy of all the zone files (no
modifications), and change the server back to dns?
Basically, I wish to get a copy of the zone files for my records.

Can the reverse be done safely?
Change to Primary, add 100 new entries to a zone file, increase the
serial number, change back to Primary, expecting the new entries to
replicate?

I would not try that too much. I would setup a std secondary for that if
you want copies, or use w2k3's dnscmd /export when you want a backup.

Thank you. You've been very helpful.
