Hello. Recently, I am studying about DNS. I have some question on the
Primary DNS suffix and connection Suffix. If I have set my Primay DNS
suffix(System --> Computer Name) and in NIC set connection suffix. Also
select "register this connection to DNS", which one will be use in DNS
registration?


Actually, I have done some test. Connection Suffix will override the primary
DNS on Client. But in DNS server, Primary DNS suffix will override it. But
still quite confuse about it. THanks.

If you have Register this connection's addresses in DNS selected in TCP/IP
the Primary DNS suffix will be used, if you have "Use theis connection's DNS
suffix in DNS registration" selected, and that zone supports DDNS both the
Primary and connection DNS suffix will be used in DNS registration.

Actually neither will override the other, the machine will attempt
registration using both domain names, if they are different.
DCs use a different mechanizm because on a DC there are two types of DNS
registrations going on. Netlogon registrations can only be disabled in the
Registry, TCP/IP registrations use a combination of both registry and GUI
settings (actually all are in the registry but some of the registry settings
are controlled by the GUI. For a DC to register its records, the Primary DNS
suffix must be a correct match of the AD domain name and forward lookup
zone.

What registrations should take place depend on the role of the server, if
the server is a DC most registrations can only be modified using the
registry. Clients use the GUI settings, which in effect control the
registry. If the client is a member of a domain, these settings can be
controlled by a GPO, which override the client settings.
