Any disadvantages of using AD integrated DNS?

[aftertaf]

I know of the advantages of this practise, but does anyone know of or have experience in certain scenarios where ad integrated DNS can have its disadvantages?
ive googled all over the place and can't find anything.
We're in a multinationaal, multisite 2003 ad environment

the only one i can think of is the dns servers have to be DCs in order to have read/write zone data.

I've not come across any down side to it. As you say there is the requirement for the server to be a DC, but depending on how you look at it that is more of a technical requirement than a down side.

Gaining the security of AD Integrated should probably outweigh needing a DC.

I hope you find this post helpful.

from Microsoft:

ADI zone will cause some AD repl overhead, for very large AD deployment, recommend primary/secondary zone topology.

I agree with that. unless you are very confident about the WAN won;t be sarturated.

aftertaf,

The only advantage that I'm aware of is if you have any DNS servers in any of your sites that don't run Windows.

Unix/Linux DNS servers would not get zone transfers from AD-integrated DNS servers, since DNS replication is integrated with AD replication. Otherwise, the only concern would be WAN traffic.

thx to all...

the extra replication bandwidth was the one i could come up with..
then again DNS will also replicate and if it is done thru AD intersites, then you have better replication & compression..

and using application partitions you can replicate certain geographical dns zones to those you specify...

we have ~20 sites...
and ~8 separate zones (.fr / .nm / .com )

not the easiest to implement to begin with but better in the long run to administer (as long as you write it down!!!) ;-)

thx again guys
