Active Directory Windows 2000 - do I need to upgrade to bring a Windows 2003 into the mix?

I have an Active Directory domain, single tree, single domain, made up of a couple of Windows 2000 servers.

Now I want to bring a Windows 2003 server into the mix.

Does it play nice with the 2000 AD? Do I need to upgrade the other servers or can they stay as Windows 2000?

    They do play quite nicely together -

    However, if you want to make the 2003 server a Domain Controller you do need to update AD. There's no problem with the other servers remaining as Windows 2000.

    There are two commands to do this:

    adprep /forestprep

    The first one must be run on the Schema Master in the domain - if you haven't moved the role this will be the first DC you installed.

    adprep /domainprep

    This one needs running on the Infrastructure Master, again this will be the first DC unless you've moved it.

    The adprep command is located in the i386 folder on the Windows 2003 CD.

    One final note, it is a good idea to wait an hour or two between running the commands to give everything time to propogate.

    There's an article on Petri regarding this too:
