I'm a bit confused as to exactly what you're asking, but let me give you a generic answer and maybe that will do: In general, when a DDNS client wants to submit a DDNS update, it uses the regular DNS resolver on the host to lookup the SOA record for the domain in question. It then contacts the primary nameserver listed in the SOA record and submits the update to that server. The resolving/caching DNS servers the DDNS client's host is configured to send queries to have no necessary relationship with the DNS servers the client sends DDNS updates to. Also keep in mind that, in the above, "DDNS client" is the host submitting the DDNS update, which may not be the same any other host you're calling a "client". In particular, your "DHCP server" will often be a "DDNS client". > Basically - the local office with the two secondarys are going to pull DNS > from the AD DNS systems but are these records going to accurate company > wide? As long as your master/slave configuration is proper, the slaves should have an exact copy of the DNS zones the AD-integrated master's have, which will include any DDNS updates. > Can 4 servers located in different geographical areas have the same AD > integrated forward zone?

The only caveat is that an AD-integrated DNS zone must be hosted on an AD DC. I've also never been able to find out if a DDNS client can submit DDNS updates to any AD DC, or if it only submits DDNS updates to the SOA server. Not that I've looked very hard. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | ------ You are subscribed as [EMAIL PROTECTED] Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=nt2000&text_mode=&lang=english To unsubscribe send a blank email to [EMAIL PROTECTED]
