I have a AD integrated DNS server(2000 advanced server) in
my firm which is running in a compaq pc with ip address
172.22.6.111.Now I got a new HP Proliant DL 380 SERVER and
I want to install the new machine as the DNS server with
the same ip address and same name with the same database
because I don't want to disturb my hundreds of
clients.Actually it should be a replacement for the old
one.
 
Now you know why people use DHCP.

If you need to run both servers in tandem for a while,
about the best I can suggest is that you use
RRAS on the AD machine, or a router, to port-map
and forward incoming DNS requests on TCP/53 on the
existing IP to the new box temporarily while you
convert. (You put the new server behind this routing
of course.)

Once your conversion is finished of course the IP
and name can (and usually should) be the same.

Normally, a server swap is done overnight or over
a weekend, and this sort of artifice isn't useful.
Indeed, because DCs can't be renamed this is
often the only feasible way to migrate platforms.

Just to add What Steve started. Can you just add it to the current domain,
DCpromo it, add DNS, Switch the roles over to the new pc (RID, PDC and
Infrastructure roles) allow all the account to replicate over night, set the
DHCP scope and all options, but do not activate it. Once the replication has
been verified, DC promo the old box.
