Hello.
I actually have a multipart question. I am about to
create a Windows 2000 Active Directory domain structure,
and need some general help. I actually need a YES/NO
reply to my questions below!

I will have a FatherDomain with 2 SubDomainss.
FatherDomain.com is the first domain controller of my
FatherDomain.com, while Child1 and Child2 are sub domains
"i.e child domains"

FatherDomain.com (Subnet 10.10.1.x/24)
| |
Child1 Child2
(Subnet 10.10.2.x/24) (Subnet 10.10.3.x/24)

DC01 hosting FatherDomain.com will host my DNS, DHCP, and
WINS. Each domain is physically located on a different
floor (and also different vlan) connected with a
layer3 Cisco router, but they are in the same office, i.e
not geographically distant.

Q1:
Do I have to install DNS on each domain controller in
Child1 and Child2? and Why?

Q2:
If Child1 domain controller is offline for some reason,
would user01 coming from ClientPC.Child1 be authenicated
by FatherDomain without problems? I mean, would
FatherDomain work as an authenticating domain if its child
domain is offilne?

Q3:
If the above answer is YES, would users notice difference
in logon times?

Q4:
Can I use the FatherDomain GPO to propagate to all client
computers in Child1 and Child2, or do I have to deploy
a GPO on each domain?

Q5:
DC01 which is hosting the FatherDomain will act as a DHCP
server, releasing IPs to DHCP clients. How can I tell my
DHCP server to release a specific IP based on where the
DHCP request comes from? I mean, a computer coming from
the 10.10.3.x/24 subnet should get an IP like 10.10.3.21/24
and not 10.10.2.21 or 10.10.1.21

Thank you for your help.

You could. Eliminates query traffic across the routers.

would user01 coming from ClientPC.Child1 be authenicated
by FatherDomain without problems? I mean, would
FatherDomain work as an authenticating domain if its child
domain is offilne?

No. Different domains, therefore different user accounts.
Q3:

in logon times?

Non Sequitor...
Q4:
Can I use the FatherDomain GPO to propagate to all client
computers in Child1 and Child2, or do I have to deploy
a GPO on each domain?
Click to expand...

GPOs can be applied at Site, Domains or OUs. In your case, you would do it
by OUs in their respective domains only.

server, releasing IPs to DHCP clients. How can I tell my
DHCP server to release a specific IP based on where the
DHCP request comes from? I mean, a computer coming from

and not 10.10.2.21 or 10.10.1.21

You would use either mutliple NICs, one for each subnet (that;s the hard
way) or use DHCP Relay Agents.
Thank you for your help.

Your welcome. I tried to keep it to a simple YES or NO, but based on your
questions, I believed you needed a little understand and short explanation.
