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 ?
