    We are looking at replacing our 1st domain controller
    with a new server. The current DC is our pdc emulator
    and Start of Authority for everything. It is our main
    DNS server as well. It's OS is Windows 2000. We want to
    replace it with Windows Server 2003. We are currently in
    Windows 2000 mixed mode. We have a second DC which is
    our Exchange Server. We have about 10 other domain
    controllers, mostly at remote sites. How complicated is
    this going to be? Are there resources on how to do it?

  2. IF you have the option to run both old and new hardware simultaneously,
    simply add the 2003 server into your domain as a member server, then perform
    the 2003 upgrade from a relatively clean box. This process is pretty well
    detailed in the following KB:

    Once you've upgraded the domain, you can transfer over any FSMO roles using
    ntdsutil or the relevant MMC snap-ins. At that point all you're worried
    about is DNS, and if it's Active-Directory-integrated it should be fairly
    seamless.

    Here's an illustrated step-by-step for replacing a single DC:

    As it's 2003, run the prep (Laura gave you the link, I believe), etc. and
    then follow the above steps.
