using dynamic dns and dynamic dhcp to replicate client A records between sites

Hi, i wonder if anybody can help, i have a question regards using dynamic
dns and dynamic dhcp, instead of using wins. I have recently setup a test
win2k server and started playing around with dynamic dns (integrated ad dns
zones as well) and dynamic dhcp, this all seemed great and worked a treat,
but i then started wondering how this would work at the other sites i have.

At the moment im running windows NT 4.0 servers across WAN links to 4 other
sites, they are all currently using wins and the wins databases are
replicating to our central site, all hunky dorey i thought, but i then
started thinking about how dynamic dns may do this instead when i move to
win2k and came across the problem that you cannot have multiple pri dns
zones with the same name, you can only have secondary zones, but these are
read only, so how would the dc's at the remote sites write to the primary
dns zone?.

The only way i can see this working is if the remote sites dont have a dns
server and instead all point to my central site which hosts the pri dns
zone, but surely this would mean an increase in traffic?

If anybody can clarify this for me then i would be very grateful.

A slightly worried and confused techy! :-),

Paul.

In Win2k on Domain controllers, make the zones on all DCs/DNS servers AD
integrated. The zones are all writable and are replicated to all DCs in the
same domain through Active Directory. You don't use secondary zones and zone
transfers can be disabled. Only DCs can have AD integrated zones.
Does this help?

Just to add, if WINS is abolished and this is an enterprise environment
(more than one subnet), then you will lose the ability to "browse" to your
resources that exist in one subnet from the other. That is still required
for this feature.

Also, when using a secondary, and a registration request is sent, the MNAME
value is queried on the secondary, which is the Master zone, and then the
reg request is sent to that server in the MNAME value, it's then registered,
and thru the zone transfer process, the seconary gets the update.

hi, somebody posted this as a reply to my question regards dynamic dns and
dynamic dhcp instead of using wins (see below), can anybody confirm or deny
this?, it seems mad that microsoft have given you the option of using
dynamic dns instead of using wins but havent come up with a way of being
able to "browse" the network to see available shares. i realise that ad
gives you the ability to add shares in and thus a client machine could
potentially browse to a share using this facility (i think, or am i wrong??)
but i didnt really want to take this step at this point, and would prefer to
carry on using netbios name resolution until im ready to do the switch.

any replies would be very much appreciated.

many thanks,
paul.
 
Hi Paul,

I posted that Paul.

Dynamic DNS just allows registration of machines into DNS. That's it. Has
nothing to do with the Browser service. Read that article down below that I
posted for specific info on how the whole Browser service works.

Sorry to repeat this, but I want you to undeniably understand that it has
nothing to do with DNS.

The requirement of NetBIOS support for the Browser Service is a well know
fact from the LanManager days of old.

The Neighborhood relies on the Browser Service.
The Browser Service relies on NetBIOS broadcasts.
Routers do not pass NetBIOS Broadcasts. So therefore, we need something to
support that. The *easy* answer to that is WINS. The *hard* answer to that
is LMHOSTS files.

In response to the bit about DNS updates to the primary DNS, clients don't actually have to point to the primary DNS server in order to update their records
dynamically. Clients query for the SOA record of the zone they need to register in. The SOA will point them to the primary and they will then register directly
with the primary at that time. This only applies to W2k, XP and 2003 machines though as only these machines support dynamic updates. It is possible
however, to have the DHCP server update the record dynamically if the DHCP server is a Windows 2000 machine.

Thank you,
