HI, All,

My case is that, I have two domains now, let's call them
domain1.com and domain2.com. Now I want to make
domain2.com as the child domaino f domain1.com , say
domain2.domain1.com.
From the book, I know I should uninstall AD on
domain2.com and reinstall it as the subdomain of
domain1.com.
The questions now is that :

1. Does there have any method to keep all domain2's user
accounts ?

2, if both DC of domain1 and domain2 are fileservers,
after making domain2 become the subdomain of domain1. How
can I make both domain1 and domain2.domain1.com's users
to access both server's resource? eg, users in domain1
can access file on DC of domain2?

No. You may migrate them to the first domain using a migration tool, but
you cannot preserve the actual accounts once the domain has been removed.

Through standard file sharing. If the two domains are in the same forest,
then the users can access the shares in another domain through the built-in
trusts.

child2.com and migrte the accounts.

Yes. But you can that already using trusts (either default trusts
within forests or NT4-style explicit trusts.)

Hi, SenSei,

Thanks for your reply.

1. It seems that when I remove directory from one DC, all
domain account will become local account ? is this right ?

2. If the fileserver is DC of a domain, will the 'default
domain controller policy' protect user from parent domain
for accessing the DC?

Hi York

I am trying to do the same thing as you have outlined
below. I have yet to do it but one solution I have read so
far is as follows:
if the domain is in mixed mode,
create a BDC on a NT 4 box in the domain that is to be the
sub domain,
syn the BDC with the DC,
uninstall Active Directory from the DC (in theory the
user, groups, share & security permissions etc, should
stay intack because of the BDC),
reinstall Active Directory and pick the subdomain option.

This option should work with Windows 2000 however I have
been told that Windows 2003 Active Directory (which I
have) is great when two companies merge their networks. In
this case one forest should be able to be rename and added
as a sub domain to the parent companies Domain. So far I
can not find a how-to on this.

Hi, Chris,

thanks for your help !

Do you know that when you remove AD from one DC, wil all
domain account will become local accounts ? if so, when
you install again, those account will become AD account
again ?

Thanks
