You cannot retain your NT4 domain with SBS2k. You can migrate the NT4
Domain to Win2k AD with SBS as your PDC. It is possible to deploy
stand-alone Exchange 2000 in an NT4 network, but my understanding is that
this functionality is there only to assist larger organizations with
migrating their domains to Win2k AD and Exchange 2000, and is not a
recommended long-term setup (but I could be wrong). Since Exchange 2000
requires AD, certain things need to be done to have Exchange work in an NT4
Deploying Exchange 2000 in a Windows NT 4.0 and Exchange 5.5 environment
does not require that the Active Directory infrastructure be fully deployed.
Because Exchange 5.5 and Windows NT 4.0 have been so popular and widely
deployed, Exchange 2000 has been designed to enable a company to begin
deploying Exchange 2000 without requiring the full Windows NT 4.0
infrastructure to be upgraded first. Active Directory Connector can be
configured to create disabled mailbox accounts in Active Directory while
existing Windows NT 4.0 user accounts can be retained for logon validation.
It is, however, important to note that Exchange 2000 users go to Active
Directory to retrieve address book information. So, the company still needs
to deploy servers running Active Directory to support the Exchange 2000
If you decide to deploy stand-alone Exchange 2000 in this manner, you will
need to make sure and do your homework and proper planning when this NT4
domain is migrated to AD, so you retain your quasi-AD that Exchange is using
and do not create a new AD forest . . . MUCH simpler route would be to
migrate the domain to Win2k AD, with SBS as your PDC. Win2k (and thus SBS)
suppports mixed mode, which let's you use your NT4 server in your Win2k
domain, although I would recommend upgrading that box to Win2k as well if
you want to keep using it.
