Creating a backup domain controller in w2k

I've been assigned a project in where I have to install and create a win2k server with Exchange 2000 server and migrate our exchange 5.5 users and folders.

I wondering how to go about doing this, the current exchange server(5.5) is currently running on a windows NT server and is also our primary domain controller.

I have installed w2k on a new server and i'm in the midsts of installing AD but the problem that I'm running onto is that whenever i choose "additional domain controller for an existing domain" i get a message saying.. 'the domain "abc.com" is not an active directory domain, or an ac domain controller for the domain could not be contacted.

Right now i'm doing this on a test environment where I have a win NT4 server running exchange 5.5 that is also a primary dc.

All I really want to to do is make the w2k a backup dc and migrate all the users/folders from exchange5.5 on winNT and once all has migrated I want to make w2k a primary dc.

Any ideas??

You need to use the Active Directory Connector to attach the two.  Here: http://www.microsoft.com/technet/treeview/default.asp?url=/technet/itsolutions/guide/deploy/d_02_tt1.asp

The problem is that NT does not support Active Directory, therefore as long as you run an NT server and a 2000 server in the same domain you will not be able to promote the 2000 server to a domain controller.  2000 can only be promoted to a domain controller if it is the only server in your network or if all other servers are running 2000 as well.

jehob.. what is mixed mode for? It's not for supporting legacy clients, it's for replicating to NT 4 DCs.

Here is a Microsoft article which outlines exactly what you are trying to accomplish:

By the way MSGeek, I didn't mean to sound like I was disagreeing with your answer....you are aparrently just a faster typist than me so I didn't realize anyone had answered yet!

Yes it does--use the "refresh this question" link at the top left.

As for what you're trying to do, we're in the final stages of doing the very same thing. Basically Exchange 2000 really needs to exist on a native mode Active Directory domain--it doesn't like mixed mode at all--so you first need to get your domain updated to Active Directory. (You can do this by upgrading your NT PDC to Windows 2000, then replacing all the other NT BDCs with 2K boxes and converting). You will also need the Exchange 5.5 Active Directory Connector installed on a domain controller before you switch the domain to native mode.

Elcuco:

If you have a BDC
1) Promote your BDC to PDC (which automatically demotes the PDC)
2) Upgrade your PDC to Windows 2000
3) Install the AD connector on your BDC/Exchange 5.5 server
4) Build a Windows 2000 Server and join it to the domain as a member server
5) Install Exchange 2000 onto the Windows 2000 member server
6) Move users mailboxes and public folders onto the Exchange 2000 server
7) After a period of succesful running, remove Exchange 5.5
9 Switch Exchange 2000 to native mode
10) Upgrade your old PDC now BDC to Windows 2000
11) Switch AD to native mode


If you don't:
1) Build a BDC
2) Promote it to a PDC (which automatically demotes the PDC)
3) Repeat steps 2-11 from above


Just make sure you do periodic backups through the migration process and have a backup plan!

Simon, that's a great answer.  It tells you how to do it, but he really needs to understand how the connector works, that is where most foul ups occur.

Question... what needs to be done regarding the hostname on the w2k server?  I want to use the same hn as the nt server so that all users do not have configure anything on their side.  So lets say my NT server's name is websrv and I name the Bdc websrv1 will I able able to change the Bdc to a Pdc with the original nt hostname which is websrv?

What would users have to configure if you had a different hostname?  Things are a lot different in AD domain.

You didn't tell us that.  I am fairly sure you will need to clean install 2000 on an different box, then install Backoffice Server on it, the upgrade Exchnage.
