Dear All,

We are Planing to Have One Forest, with Multiple Domains Trees as the
following :-

1. KTC.COM
2. MUX.COM
3. TRU.COM
4. LON-UK.COM

and Each one of the abouve Domain have 25 users as the following :-
1. KTC.COM ( Have 25 Users ).
2. MUX.COM ( Have 25 Users).
3. TRU.COM ( Have 25 Users).
4. LON-UK.COM ( have 25 Users ).

So the Total Users will be 100 Users.

i am going to install KTC.COM as the Forest Root Domain, & Install DNS
server on one Machine and configure one Forward Zone with name of the Forest
Root Doamin which is ( KTC.COM) and this DNS server is the Root ( .) .

and i found that its Working and the Forest Root is Working and the Domain
Controller is Able to communicate with the Default DNS.

All of 100 users in the Same Network with this IP-Address Schema (
192.168.1.X ) / 24.

Now, i want to install the Domain ( MUX.COM) as New Domain Tree in the
exsisting Forest to share the same Exchange Box.

so what i did is :-

1. Bring New Server.
2.Install Windows Advanced Server 2000 Enterprise edition.
3.Put this IP-Address 192.168.1.20 & the DNS For this server will be the
Same which is 192.168.1.20.
4. Install the DNS on that Machine.
5.Run this Command ( DCPROMO).

Here is the Problem, i found that , while i am trying to install the domain,
its display error message which is ( The Domain Controller for Domain
KTC.COM, is Not available ).

so when i face this situation, i said to my self, this is because the Domain
( MUX) is unable to find the DNS and then unable to find the Domain
Controller for KTC.

( Because the Role is , the Active Directory Clients - WinXP-PRO, Win
Server, Win2000 Pro, Win98 ...ETC, should first ASK there DNS server to Get
from him the Specifc Resource Recourd , and in this Case i was installed DNS
on This Machine and i made it as Root , which is Wronge ).

So what i did is :-
1.uninstall the DNS server from the Domain ( MUX.COM )
2.Create Forward Lookup Zone with this Name ( MUX.COM).
3. Configure the Server to register him self in the DNS of the Domain
KTC.COM ( By Changing the IP-Address of the Preferd DNS server, to be the DNS
server of the Domain KTC.COM , instead of MUX.COM ).
4. Run again the DCPROMO Command .

then i found that its working Perfect. without any problem and the Trust
Relation ship is created automatically and the Users in Both Domains are able
to access each other .

=====================================================

My Questions is :-

1. Can the DNS Host Multiple Domains like My Situation , or Not ?

2. is there any Problems i will face it in the Future from this Design ,
with One DNS Server and hosted Multiple Domains on it , and the clients for
MUX , will recorde them self only in MUX.COM Forward Lookup Zone, and the
users of KTC.COM, will register them self in the KTC.COM Forward Lookup Zone.
, do you excepect any Problems in the Future ?
=====================================================
I tested it from The Clients which is they are register them self in The
Forward Lookup Zone of the domain KTC.COM, by using the command NSLOOKUP, and
i found that they are able to commnuicate with the DNS server & can see each
other in this Forward Lookup Zone only with the name of the Domain ( KTC.COM
), while they are unable to see any Resource for the domain ( MUX.COM ) at
all, and the same situation for MUX.COM, they are able only to see the
Resouce in the Domain MUX.COM only and unable to see the Resource in KTC.COM.

so do you think i am correct , or not ? Please Help ?

Hi - you finally made it to a relevant group. :)
Why so many domains? You're making life pretty tough on yourself. What's the
reasoning behind this?

Hi Mohammed,

Remember that to have 4 domains you at least need 4 DCs (1 DC per
domain). However it is recommended to have at least 2 DCs per domain
for redundancy purposes. With 2 DCs per domain you still have 1 DC if
the other one dies.

At least have 2 DCs for the root domain! If that one dies and your
backup is bad the rest of your forest is screwed too!


When accounting for redundancy for each domain you will need at least
8 DCs, just for 100 users. In my opinion, that is a lot of money on
hardware and licenses for just 100 users.


I’m very interested in the answer to the following question:

Why are you installing a total of 4 domains in one forest for a total
of 25 users per domain (100 user for the whole forest)?


Cheers ,

DNS can host thousands of domain names (zones).

My question to you: What is the design requirement leading to multiple
domains for 100 users? I believe you can easily create one domain for all
100 users, set them in their own OUs, control access permissions on
resources by the respective groups you create for the 4 domains originally
intended.

Otherwise, can you enlighten us on your reasons behind this?

Thank you.

=================================
 
My answer has not changed just because you are now asking in
the correct newsgroup; i.e. if you must have all those domains,
since they are on local on that small private IP network, just
let the DCs of the forestroot domain act as the only DNS servers
for the entire forest, that is your most simple route.
