We have a large pure Windows 2000 AD running in native
mode. The company recenty went through a merger and as a
result the companies email addresses and web page address
are changing. Unfortunately it would dappear that
changing our windows 2000 domain name is not going to be
as easy. This presents us with a problem as our previous
system meant that users used their email address to logon
to the AD. Is there any way that we can maintain the
current AD backend but have the users appear to logon to a
new domain i.e the front end looks like it is logging onto
a new domain but infact it is still logging onto the
original domain name. hope this isn't to confusing
 
Hi,

in Windows 2003 you can change the domain name. However. If you are talking
about that the user log on with the UPN you can change the UPN suffix to
your new domain. Your can also modify the email adrresses to the new mail
domain by adding a new entry to the recipient policy.

if you're just going to change to domain name (web site ,
exchange - mail) you should register your new domain at
your ISPs and create new mx record.

Good Luck

I would assume that when you mention that users use their
emails to login you meant that they log in with the UPN ie
(e-mail address removed) as the username.

If that is the case you can use AD Domain's and Trusts to
create another UPN suffix that will match the new domain
name and then assign the new suffix to each user account
in AD.

To create a new UPN suffix:
Open AD Domain and Trusts
Right Click on 'Active Directory Domains and Trusts' (Left
tree)
Select Properties
Add new UPN suffix

To assign to new UPN suffix to accounts:
Edit user properties in AD Users and Computers
Account Tab
Use drop down list on User logon Name to assign new UPN
suffix. (you might want to script this step with ADSI if
you have lots of accounts)

Hope this helps

Yes Paul you are quite correct our users do use their UPN
to Logon. I had thought about creating a DC with the new
domain name and then trusting the new domain. The issue
then is what would happen to all the policies that run as
the user logs on in the old domain. Creating all the
policies again in a new domain would be very labour
intensive as there are 70 sites covering 6 countries. I
would be very interested in your feedback.
