Setup.exe /forestprep for Excahnge 2003 in WIndows 2000 Domain?

Hi All,

I keep reading different articles from Microsoft regarding installing Exchange 2003, therefore help is required urgently.

I want to install a Windows 2003 Cluster and Exchange 2003 into an Existing Windows 2000 Native Domain.  There is a current Exchange 2000 single node server running in this organisation and there is just the one domain in the forest.

We do not yet want to install any Windows 2003 DC's, due to budget constraints.

I was under the impression that you only had to run the /forestprep and /domainprep from the Exchange 2003 CD to extend the current schema?  I thought the ADPrep utility was for installing Windows 2003 systems as DC's?

Do I need to run both forestprep's and domainprep's from Exchange 2003 CD and Windows 2003 CD?  And/Or will there be an issue if I was to run Exchange forestprep and not ADPrep when, in the future, I want to install a Windows 2003 DC and therefore will have to run ADPrep?

Thanks in Advanced.

    You need to run setup /ForestPrep and setup /DomainPrep to allow Exchange 2003 servers to be added to your domain.  the adprep /ForestPrep and adprep /DomainPrep aren't required.

    there are two schools of thought here.

    One is that if you are making a number of changes to the schema, you could incorporate adprep into this and have one lot of domain replication.
    The other is that you don't want to complicate matters now by running adprep unneccesarily.

    I would be tempted to run ADprep now and get it over and done with.

    This is what I thought but unfortunately time is somewhat against us.  Are there any MS Article's to support this?
