Thanks for a prompt reply.
do you mean Registrar = DNS service (Windows 2003)? or i need to buy
another software?
Can i use the DNS services in Windows 2003?
Because of limit space & costs, can i assign a server with 2 true IP to
avoid "2 server".
Thanks a lot.

Just to clarify, you can buy a domain name via a Registrar's website and
typically they will host the dns side on their system, plus the domain
name is "known" at root / tld server level. You can usually choose to
forward dns requests to your own server but you must have mx, web, name
servers confirgured the instant you do it or your domain will not be
found by the rest of the world or not issue answers to queries for where
your domain accepts email, where the website is hosted etc. If you have
a simple setup / requirement you're probably best leaving dns with the
Registrar and simply map your website, email where you want them to go
and benefit from the Registrar's fault tolerance and server
distribution. If you have a complex setup like alot of mail boxes then
the Registrar is probably going to charge and so the total cost starts
to climb whereas if you host your own dns, you have total control and
can implement changes quickly - but note you also have the
responsibility for good configuration, security, downtime etc.
