Re: The difference between Mixed and Native Modes in AD vs Exchange

You are comparing apple to oranges.

Native mode for AD is not always the same as Native mode for Exchange. native mode Exchange 2000, means that you will no longer be able to install exchange 5.0/5.5. Unless there is some reason that you foresee maintaining backwards compatibility with exchange 5.5, go ahead and advance to 2000 native mode.

With active directory running in a domain with 2003 FMSO master, native mode requires no more DC's running either NT/server 2000, but you can bring it to mixed mode. Bringing exchange native mode at the 2000 level would be supported in a mixed mode domain with W2K and W2K3 servers.

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 Directory 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?

I want to bring all of them to Native Mode. Can I just upgrade all 4 of the
existing 2000 servers to Native mode in the AD properties? 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.

I appreciate any help and direction you can give me.

Thanks in advance,
