I recently had a new job in the it department at some company, so I started to check what the previous administrator did of configuration for a Microsoft windows 2003 based network, I’ll explain a bit about it :

·         We have one forest:

World.com

·          two domains:

1-      [strong]world.com     ???????[/strong]

2-      Tokyo.world.com

The world.com  and the  world.com  are in the same physical location, Tokyo.world.com is in other physical location.

·         The servers are:

Jon.world.com = 192.168.5.1

Mic.world.com = 192.168.5.2

Chan.tokyo.world.com = 192.168.180.1

Jon.world.com = root + DNS + DC + GC

Mic.world.com = file server

Chan.tokyo.world.com = DNS + DC + GC

So first in  world.com  I checked the DNS by using nslookup on jon.world.com here are the result :

Nslookup

>default server:jon.world.com

>address: 192.168.5.1

>192.168.5.2

Source:jon.world.com

Address:192.168.5.1

Name: mic.world.com

Address:192.168.5.2

>mic.world.com

It gave a correct IP which is 192.168.5.2

So I tried the following :

>192.168.180.1

Source:jon.world.com

Address:192.168.180.1

***jon.world.com can’t find 192.168.180.1 nonexistent domain

>chan.tokyo.world.com

Source:jon.world.com

Address:192.168.5.1

Non-authoritative answer:

Name:chan.tokyo.world.com

Address:192.168.180.1

>world.com

Gave me two IP  192.168.5.1  192.168.5.2

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

I open dns console on jon.world.com:

Forward lookup zones are fine, but the reverse lookup zone are missing all the subnets in the world.com location, except for the subnet of the servers which is 192.168.5.X

I open dns console on chan.tokyo.world.com:

Forward lookup zones are fine, and the reverse lookup zone contain all the subnets in the Tokyo domain.

!!!!!!!!!!!!!!!

at the clients side is the following:

When I press Ctrl+alt+Del at the logon screen window, and checked the logon to, I see two domains ( [strong][em]London[/em][/strong] , tokyo), when I asked a user in the location where world.com is located what is London, he told that this is the domain name that they logon to since a long time, and its working fine, he logged on successfully .

I checked the TCP/IP settings of the net adapter in the DNS suffix written world.com

But in the Tokyo domain the dns suffix at the clients side is Tokyo.world.com

Well the root is world.com but the domain in it should be London.world.com and the server name is jon.london.world.com?????????!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Am not sure if I understood the previous conf, could any body expalin plain text, help plz.

thank you in adv.
