Do DNS and DHCP have to run on the PDC?

[none]

Hi

When setting up a new win2000 pdc, is it necessary to have DHCP and DNS
for a domain running on the same machine? Can I have the primary dns
and dhcp services running on a different machine or do they have to run
on the PDC in order for the PDC to function correctly?

Thanks for your help

T.

No but you need to make sure the PDC points to the DNS server (for DNS in
the properties of TCP/IP) along with all other AD clients.

No.

It is not uncommon but it is not required.

It is necessary to have Dynamic DNS somewhere if you
have AD, and when you are creating the first DC in the
domain, the most natural place is to put it on that new
DC.

There is no real relationship between DNS and DHCP
except that DHCP might register the client addresses in
DNS (if configured to do so), and might give out the DNS
settings that clients use.

There is no relationship between AD and DHCP except
that AD Authorization may be required for DHCP.

There is also a (relatively) minor security issue with doing
that if you use Dynamic updates from the DHCP server AND
use the DNSUpdateGroup.

Can I have the primary dns
and dhcp services running on a different machine or do they have to run
on the PDC in order for the PDC to function correctly?

There is no "PDC" in Win2000 domains, and the "PDC Emulator" is
not related to DNS nor to DHCP.

Thank you both for the reply. We are creating a new domain along side
an existing domain. Is it feasible to point both domain master browers
at the same DNS and DHCP server - then get the DHCP server to serve one
range of IP addresses to one domain, and another range of IP addresses
to the other domain?

No. DHCP is not domain aware (except for authorization.)

DHCP doesn't not care which domain, or even which operating
system the clients use.

You can only make such distinctions IF you use separate subnets
for the machines of each domain.

One can use "DHCP user [defined] classes" but these do not work
for the IP range itself nor the subnet mask. (Classes do work for lease
periods and other options.)

BTW, if you have the clients on the same subnet, why would you
care which addresses they receive? (I can conceive of such being
important, but it would be a very special case.)
