2 Forest in one network. Not able to connect domain


C

commander data

We currently have a W2K Native Domain/Forest (domain1.com)
Now I have created a new W2K8 Forest (domain2.com)

I have run adprep /forestprep on the W2K Forest and all was successful

So now we have 2 forest. I can connect by IP address to the newly created
W2K8 domain controller. But I cannot join that new W2K8 domain. The only
Domain/forest I see is the W2K Forest.

Both of the Forest domain controllers uses the same IP Private range:

W2K DC: 192.168.0.1
255.255.255.0
192.168.0.254

DNS: 127.0.0.1

W2K8 DC: 192.168.100.50
255.255.255.0
192.168.0.254

DNS: 127.0.0.1


Is this a problem? As I said, I can ping both domain controllers from my
workstation. My workstation is not a member of any of the domains (is in a
workgroup) Only the W2K Domain I can join. The W2K8 in the other forest I
cannot join

help would be appreciated

Hello commander,

You can not join one forest into another. That is not possible. You have
to create a 2 way trust between them and use ADMT to migrate them.

Thank you for the quick response Meinolf
I have looked at a trust between the W2K Forest and the W2K8 Forest
But there is no Trust Forestrelationship possible because it's a W2K Forest

How should I proceed? Do I have to creat an external trust between them?

And if there is a trust, than I can join a computer to this new domain?

I have ran adprep /forestprep on the W2K Forest (updated to 44)
Should I also run the domainprep? We are not planning to install W2K8 DC in
the W2K Forest

Thank you in advanced!

this is fine
you can not join one workstation to the w2k8 domain as the the wrkstation
is still using the DNS server in w2k domian
change the dns server setting for the client you should be able to join this
pc to W2K8

the interesting part would be when you cteate a trust and start migrating
users form one domain to another
let us see what challenges do face in this process

Hello commander,

Sorry i overead the part with the workstation. To join a workstation to the
2008 domain configure it with the correct ip addresses from the 2008 network.
Also for the DNS on the servers i prefer the use of the real ip address,
it works with the loopback address.

Create a 2 way external trust.

Best regards

Hello commander,

You do not have to do anything with the schema on the 2000 domain when joining
a workstation to another domain. Workstations are not effected from the schema.

Ok,

I'll well create an external trust between those forest.
But how about dhcp? I have both dhcp servers running in both domains
Both dhcp servers have a 192.168.x.x range Will it give any problems?

Hello commander,

When you run to different subnets in one physical network with DHCP servers
you can not achive that clients will get the correct ip address for the subnet
you need, use fixed ip addresses for all or separate the networks with router's.
