how to connect two dc's of different domains

I have two domain controllers running windows 2003 server. Assuming, 1 is
1.local and 2 is 2.local. They are both private organizations in the same
tcp/ip stack. Now they want to merge and share information. I assume I need
to create a trust. Does anything need to be done with DNS? How about with the
clients from either domain?
These domains are two separate forests.

Any help would be greatly appreciated.

 

hello,

what do you mean by "in the same tcp/ip stack" ? same subnet ?

You will have to make each domain be able to resolve the other, by
configuring zone transfer or forward.
Then you will make a trust between both.

1/ what do you want to access from the other domain ?
2/check the clock between domains (<5 mn)

 

Yes, same subnet. Which is more efficient? I prefer a forward, but have never
done either. How is this done?

Do you mean to make both clocks the same time???

 

Are they on the same lan (vlan / switch) or separated by firewall ?
Same time means that both domain clock must be near in time. No more than 5
minutes between computers of both domains

 

Yes same switch.

 

ok, i was afraid of firewall and duplicate network address.

Should be ok

 

How do you setup a forward? Does it need to be setup on both dcs?

 

You should do it on all dns server of both domain

On the DNS MMC, right click property on the server,
forwarders tab
new
type in the dns domain of the other AD domain
add the IP of the other domain dns servers

Do the same on all dns server on both side

then test dns resolution

 

Thanks!

 

I want to connect two domain controllers both domain controllers present on same location, office but on different subnets
explained below:

abc.com
OS: windows 2003
IP: 192.168.xx.x/24
Gateway: 192.168.xx.xx [*ip of the DSL router]

****************


xyz.com
OS: windows 2003
hosted in VMWare
IP: 192.168.xx.x/24
gateway: 192.168.xx.x [*ip of the router]


*both IPs are from the same router

How can I connect two domains and share the resources with each other.

Regards,

Rashid
