My question is can I have active directory running on only one server in a NT 4.0 network? I will be adding a Win 2000 server to our network this server is also going to have exchange 2000, can exchange run with out active director?

Currently runnung exchange 5.5 with service pack 4 on NT 4.0 with service pack 6 Im not planing on upgrading this machine. I purchased a new server for Win 2000 server and exchange 2000.

Which would be the best way to configure this to my network with or without active directory?

1. A Windows 2000 Active Directory (AD) Domain Controller (DC) CANNOT exist in an NT4 domain.
2. To migrate from an NT4 domain to a Win2K domain, Win2K (and AD) MUST be installed on the NT4 PDC.
3. NT4 BDCs can exist in a Win2K AD domain.
4. Exchange 2000 MUST have access to AD to function (although it doesn't need to be installed on a Win2K DC).

At this point you really only have 2 options:
1. Convert your domain to Win2K and Active Directory.
2. Continue to use Exchange 5.5.If your primary goal is to move Exchange 5.5 off the server that presently hosts it, you can take your new Win2K server (leaving it as a member server) and join it to the NT4 domain; install Exchange 5.5 as an additional server in your current Exchange site; move all users and mailboxes to the new server; remove the old server.
