I have one primary server and 2 secondary dns servers. Now i would like to
make them AD integrated.
Firstly what i was thinking was to make the primary AD integrated and wait
about 15/20 mins and then one by one change the other secondary dns servers
to AD integrated.

If i do it in this order will this have any implecations on the
network/domain while i do this or shall i wait till after hours.

Please advice.

Thank you

No don't change the secondary DNS to AD integrated, delete the secondary
zone, the AD will get replicated. Win2k will usually convert the zone to AD
integrated if you restart the server.
If you try to convert a secondary zone in to AD in Win2k3 it will cause an
error, that there is two zones of the same name in AD.
 
You mean delete the forward look up and reverse look up zones in the
secondary DNS servers first then change the role of primary dns server to AD
integrated.
And this should automatically generate/re-create the AD integrated zones on
the current secondary servers.

I have win2k domain

Yes, in Win2k AD integrated zones will automatically want to replicate to
all DCs in the same domain with DNS installed.
If the DNS is not on a DC, it won't replicate to that DNS through AD in
Win2k.
 
Thank you very much,

But this is the first time i am trying to change the primary to AD
integrated and when i come to apply it it comes back with a warning. ' A
zone with this name already exists in Active Directory. What do you want to
do? and the two options are a) Discard the new zone, and load the existing
zone from AD b) Overwrite the existing zone in AD with the new zone.'

Just would like to know what will be the the better option and also can you
please explain exactly what each option will do.

And also does that mean that I will not be able to have DNS on other servers
which are not DC's.


Also please can you reassure me that If i change from primary to AD live on
the network that i would not encounter any disruptions.

Thank you once again.

If you are getting this obviously you've had AD integrated zones before and
they were changed.
What do
you want to do? and the two options are a) Discard the new zone, and
load the existing zone from AD b) Overwrite the existing zone in AD

Use this:
b) Overwrite the existing zone in AD with the new zone.'

No it does not, but under Win2k only DCs can have AD integrated zones, non
DCs or DCs in other domains will have to use Secondary zones because Active
Directory won't replicate to them.
Also please can you reassure me that If i change from primary to AD
live on the network that i would not encounter any disruptions.

You should be just fine.
 
Thats excellant, worked brilliantly. Thank you for the re-assurance.

one other q;
The secondary DNS's on non DC's they will be updated as they are,
automatically?

Any secondary zones will by default use the refresh, retry and Expire values
on the SOA record for their zone updates. Optionally, you can enable notify
on the Zone transfer tab to notify the secondary zones to do an incremental
zone transfer. Using the notify option may cause 3000 run time events on the
secondary DNS server due to the continual incremental zone transfers due to
DDNS registration, you can ignore the events and keep in mind as long as you
are getting 3000 and 9999 events the secondary zone has current data. (the
9999 event is caused from the event log ignoring the 3000 events)
