Can I migrate Exchange 5.5 SP4 Servers (NT4.0) to Active Directory (Windows 2000) architecture without upgrading to Exchange 2000 on Win2K servers?

Had to re-read your question because I misinterpreted it the first time (maybe I still am).

If you are asking whether Exchange 5.5 on an NT4 server can exist in an Active Directory domain, the answer is yes.

If you are asking whether the server that hosts Exchange 5.5 can be upgraded to Win2K in an Active Directory domain, the answer is still yes.

However, Exchange 5.5 cannot be made to use Active Directory for its directory information. It will still maintain its own directory services.

To totally integrate Exchange into the Active Directory environment, then you would need to migrate to Exchange 2000 (Which must be installed on a Win2K Server).

I hope this answers your question.

Answer one has already answered the question. I just want to add my 2 cents. If you use Exchnage 5.5 with Active Directory you will have to install Active Directory Connector which will synchronize Exchange 5.5 with AD, Exchange 5.5 will however still use it's own directroy. Active Directory Connector will just make sure that when you create a new user it will add it to Exchange 5.5.
