Got a DNS ??

Currently DNS runs on my Win2k server but because of the
load of other apps on it, I want to move the DNS service
to another server.

1.) Can't I just install the service on another server,
creating all the records and the like?

2.) I can also update the DHCP service to point to the new
server.

Thanks.

Sure. If you only have one (or a few) zones, you might also consider
making the new server a temporary Secondary to the first (for each zone)
and then just let zone transfer handle the records themselves.
2.) I can also update the DHCP service to point to the new
server.

Of course, try to do this well before you remove the old DNS so that
clients will always point at a functioning DNS server.

Yes.
You can install DNS on the 2nd machine and either create secondary zones (if
the 1st uses standard primaries) or AD integrated (if thats what the 1st
uses) and let the data replicate across.

Once thats done you can remove the 1st DNS service and convert the
secondaries to primary zones (or do nothing if you use AD zones)

2.) I can also update the DHCP service to point to the new
server.

Yep.

Shorten the lease to a couple of days so that you can move the clients from
one server to another more rapidly

The earlier suggestions will likely do the job for you or you can use a
script I wrote for this purpose. To locate and download the script,
simply google for "dnsdump".

Is either of these machines a DC?

Depending on the answer to the question I asked the second can be added as
either a secondary or AD integrated.

You may want to just add the second server then add it to the Scope in the
Preferred position with the current DNS as alternate, especially if the
current DNS is a DC with an ADI zone.
 
There is also a Knowledge base article on this subject. 280061 HOW TO: Move Windows 2000 DNS Zones to Another
Windows 2000-based Server http://support.microsoft.com/?id=280061.

Basically, set all the zones on the current DNS server to standard primary zones and stop the DNS service on both servers.
Copy all the zone.dns files within winnt\system32\dns to the new DNS server in the same location. Export
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DNS\Zones from the registry on the old DNS server and import it
on the new DNS server. Start the DNS service and the new DNS server is ready to go. There is no need to rebuild the zones.
Of course, make sure all machines now point to the new DNS server, either via a DHCP update for DHCP clients or via manually
adding the new DNS server on your static machines. If you are hosting any Internet domains, you'll need to update your
registrar with the new IP address of the new DNS server.
