Re: Confusion between Mixed and Native Modes adding a Server 2003

Hi,

Thanks so much for your response. I had a feeling and by reading
everything I can get my hands on that Mixed/Native was a different
animal for AD vs Exchange. The do want me to change their older DC's
to Native Mode so that's what I'm going to do first. They do not have
any NT boxes so we should be OK with that.

Cool beans.

Since the only machine I will be promoting is the 2003 server. One of
the server 2000 boxes has Exchange and is already a DC so I won't
have to worry about promoting it. Thanks for the warning about
promoting an Exchange Server to a DC.

....or demoting it to anything else. :-)

If I understand you correctly what I'm going to do is the following:

1. Since all the 2000 servers are in AD Mixed mode I will change one
of them to Native Mode (not the one where Exchange lives). This
should propagate to all the other 2000 domain controllers. Are there
any caveats I should be looking for when I do this? I will have a
complete backup of that server before I do anything just for safety
sake. If you can think of anything else please let me know.

You aren't changing any *server* to native mode. You're changing the
*domain*.

2. Once the change to Native Mode has propagated to the other DC's I
will take the server 2003 disk and run adprep /forestprep on the
server 2000 domain controller that I changed to AD Native Mode. Also
after backing up once again.

Sure.

3. I'm pretty sure and correct me if I'm wrong that once everything
is OK I should be good to go to promote the 2003 server to a domain
controller using dcpromo.exe and, in a sunny day scenario, I will be
good to go.

I'd say so, yes.

The link you gave
http://technet.microsoft.com/en-us/library/aa996524(EXCHG.65).aspx is
not an active link. Did I type something in wrong?

Hmm....works for me from here. Try again?

Thanks again for your help,

Hi,

I just started a 6 month job at a company to do some Windows work
for them. The company has 4 Windows 2000 server machines with
replicated Active Directories. One 2000 server is the master AD and
also is running Exchange 2000. My task is to bring up a new Windows
2003 server box and get AD on it.

I'm confused about the difference between Mixed and Native Modes
with 2 different aspects.

As I said above there is an Active Direct
ory instance on the exchange
box and 3 other Domain Controllers.

When I go into the Active Directory Users and Computers properties
it says "Mixed mode (supports both Windows 2000 and pre-Windows 2000
domain controllers)". However when I go into the actual Service
Manager for exchange on the same Exchange Server box the properties
tell me the following: Native Mode (no pre-Exchange 2000 servers).

I'm unsure what the difference is between the two modes in the two
different locations on the Exchange box. Does anyone have any clue
of what I should do?

You're mixing up Exchange's mixed/native mode with AD's mixed/native
mode. You're in Exchange native mode, and AD mixed mode.

AD: http://windowsitpro.com/Articles/Index.cfm?ArticleID=7156
Exchange:

I want to bring all of them to Native Mode.

OK, that's fine....but why? It isn't relevant to your task at hand.

Can I just upgrade all 4
of the existing 2000 servers to Native mode in the AD properties?

If you do this on one of your DCs it will be done for all of them,
as it's a domain level thing.

The
reason I have to do this is that I have to run the 2003 dcpromo.exe
/forestprep on the old Exchange AD to be able to promote the 2003
server to a Domain Controller.

You mean *adprep,* I think, yes?

(Never ever run dcpromo on any box running Exchange. Exchange
shouldn't be running on a DC anyway (you *can* but it's not great
practice), but if it is one already leave it that way.)

I appreciate any help and direction you can give me.

Thanks in advance,

See if this helps. http://www.petri.co.il/windows_2003_adprep.htm
