Serious NT / W2k / Exchange 2000 problem

Here's the scoop:

I am adding this domain via a new server as a child to a parent domain - W2k domain - tree is child / parent domain is forest.  In the parent domain I have an Exchange 2000 server that houses all my companies email (including other child domain in the forest).

The parent/child setup works fine.  The problem - I cannot use Active directory migration tool to move the users from the parent to child (forest to tree) because I cannot put my 2000 server in native mode.  This is due to having to run an NT server as a member server on the domain that controls a critical piece of equipment that we cannot move at this time.

so - I can recreate all my users on the new domain and log in with that option.  that's fine - the problem is the email.  Everytime I create an email account (whether from the AD wizard or on the exchange server) it tells me I cannot log onto to the default exchange files when I try to setup the user account in outlook or that the username cannot be resolved.

any ideas?

Sorry, wrong thread.
Im not to clear on your network design.

Is there an AD structure already in place?
Are you trying to move emails to a new email server?
Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

make sure you have a DNS entry in your Child Domains DNS Conroller for the Master DC and Exchange Server.
Have you created a recipient update services ( in exchange system manager - > recipients ) for the new domain - otherwise exchange won't add them to it's address list - or even assign them addresses ( hence lack of resolution ).
Switch Windows 2000 Server into Native mode.  The whole mode's issue is related to domain controllers ONLY!!!  If you have any NT4 DC's then they cannot pull a copy of the domain data, and thus perform domain functions if Win2k is in native mode.  If you have no NT4 DC's then switching over to nativ emode will have no effect on your environment.

In the setup you mention, the NT4 box is a member server, ie configured as a client like Win2k or WinXP  so switching to native mode will have no effect on this box.
Good Answer.. sometimes it's as obvious as the nose on your face.
