Exchange 2000 in a 2003 Domain

By razz2 ·
A client has migrated from a 2000 Domain to a 2003 domain by
using 2 new servers. The addition of the 2 new servers went fine
as did their promotion to ADC's. The old 2 controllers will be
demoted in the end. The current setup is as follows:

ADC01 - New 2003 AD Controller

ADC02 - New 2003 AD Controller

PDC01 - Old 2000 DC still running AD for now but will be
retired

MailServer - Exchange 2000 and 2000 AD Controller. The server
will be demoted but stay running 2000 server and exchange
2000

All is running fine but now comes the Exchange System Manager
question. It must be installed to admin exchange from AD User
& Computers but can the exchange 2000 System Manager be
installed on 2003 server? I know about Exchange SP3 adding
2003 support but what about installing it? You can't install
Exchange 2000 on 2003 server so how do you admin it? You
can't install 2003 Adminpak on server 2000. Catch 22?

I am assuming the only way is from an XP workstation with 2003
Adminpak and Exchange System Manager but then, according to
the MS KB, you can't have outlook on the same box as any
exchange component. (OK, Outlook 2000 and 2002 have worked
and the client has 2002).

What about Exchange 2003 System Manager on the 2003 ADC
manageing the Ex2000 on Win2000? The issue there is licensing
if they don't have Ex2003.

Thanks for any ideas.

the Exchange System Manager stays on the Exchange box.

If you need to get in and manage Exchange, you have to do it at the Exchange box.

Thanks for the response CG IT. Perhaps my question was worded weird, sorry about that. I know the ESM needs to be on the Exchange Server and that 2003 does not support Exchange components being installed, but since the 2000 box does not support the 2003 admin tools how can exchange tasks be managed from AD Users & Computers? From XP I can always install the Admin tools and Exchange SM, but then Exchaneg ADUC admin can't be done in the server room. So, is there anyway to perform Exchange tasks from AD Users & Computers on a Domain Controller? For Example if the client owned a Ex2003 CD he could install the 2003 System Manager even if he was not upgrading to Exchange 2003 yet, correct? Is there anyway to to do this without using Ex2003 System Manager?

Thanks again,

razz

we do this all the time with the small business server edition which has exchange on the DC.

leave the production server which is the DC and has Exchange on the network. Create your new W2003 Server with Exchange. You have to use a different NetBIOS name and server name for this to work. you use the ADMT to move from the old production server to the new production server. then use exmerge to move exchange or better yet just have users save all their emails to a pst file then just copy them over to a user folder. once workstations are being serviced from the new DC, run outlook and import the pst.

This is what the ADMT and exmerge tools are for. I've done this and it works really well [except for the amonut of time it takes to move.

The thing is, your moving to a W2003 server. the tools are for W2003, your getting rid of the W2K so what's the problem?

Actually that is the problem. They are keeping the exchange 2000 on Windows
Server 2000. Only the Domain Controllers are going to 2003. Man, if they would
upgrade the Exchange to 2003 this would be easy.

(Side note:I have also used the exmerge etc although I have know those that
install a temp exchange server on the domain and move the mailboxes to it. And
then they re-install the server as 2003 and install Ex2003 only to transfer the
boxes back.)

Back to the question at hand. The 2000 (both server and exchange) is staying.
There will be no ex2003 on a Server 2003.

Now is the picture clearer? An Exchange 2000 server running on Windows 2000 in
a 2003 domain. AD on the 2003 server can't run the 2000 System Manager and
the 2000 server box with Ex2000 on it can't run the 2003 tools. Catch 22. Only
an XP box can run the 2003 adminpack and the 2000 system manager together.
That is what I was hoping to find a real world "work-a-round" for. I want to be
able to be in the server room, on the 2003 AD controller and be able to add a
user and mailbox at the same time.

It just may be a dream though.

I rated this for now but if I get no other ideas please post a small note so I can
give you the points.

Thanks again,

razz

ok

Exchange 2000 will run in a Windows 2003 AD environment BUT, and this isn't in regards to your question but important, the Exchange 2000 schema and the Windows 2003 adprep/forestprep and adprep/domainprep mangles attributes in Exchange.

here's a KB on this http://support.microsoft.com/default.aspx?scid=kb;en-us;314649

Exchange 2000 will run in a Windows 2003 AD environment. here is a Microsoft KB. down at the bottom is some white papers on Exchange 2000 in a Windows 2003 AD environment.

This is the best suggestion I can make for you. As I said you can have Exchange 2000 in your Windows 2003 AD environment and as far as the system manager tools, leave em on the Exchange box.

Exchange 2000 does intergrate with Windows 2003 AD so that when you create a new user a mailbox is created in Exchange.

I have the answer I need now, butI am interested in your response to this so I do
not want to close the question. Please either respond or at least just jot a quick
word or two so I can assign the points now.

Taking your talking points in order:

1) Exchange in a 2003 AD Domain.

I know about the mangled attribs and all that is done already. I ran the adprep /
forest, and adprep /domain and the prevent mangeled attribs scripts and the
integration is complete and great.

2) Leave the System Manager on the exchange box.

Then there is AD integration, but no User and Computers integration which takes
us to #3.

3) "When you add a new user a mailbox is created"

This is not the case. Sitting at the ADC01 with no ESM installed I created a user.
The normal " do you want to also create a mailbox" never appeared. The user has
no mailbox in ExSysMgr and it can't be logged into with Outlook WebAccess.
Moving to an XP box with all the tools if you go to the user in ADUC and select
Exchange Tasks the Create Mailbox is available. So, the conclusion is that
interactivly standing at a 2003 AD controller there is no way to add a user and a
mailbox. The Ex2000 integrates with 2003 AD and the global catalog, but with
out a System Manager component the only way to manage users along with the
standard Exchange Tabs in User properites is from an XP box. That is a reason to
upgrade alone in my opinion.

CG IT, thanks for your time. Like I say, if you have a comment great otherwise
just type a word or so so I have a response to assign points to.

Theres gotta be a way. Can't imagine Microsoft fumbling this one. What good is AD Users and Computers is a mail box isn't created simply because your running Exchange 2000.

the only KB I could come up with is this one

http://support.microsoft.com/default.aspx?scid=kb;en-us;821507

which I don't think addresses your problem but is close. Think I'll ask someone over at Microsoft about this and see what they say.

by razz2 In reply to

Yeah, I saw that KB article too but not really it. The answer to you question is ADUC is useless without ESM.

well this is what I got back from those in the know.

Install the Exchange System Manager from the Exch 2003 disks onto the DC
you have in mind to use that with.
