    We are planning on migrating from our existing SBS 2000 server to a new SBS
    2011 server sometime soon. Long story short, but we plan on starting fresh
    with a new AD. Copy all data & export mailboxes from the old server and
    import it all to the new server.

    My plan would be to stop/disable DHCP on the SBS 2011 server and plug it
    into our network. Both servers would be on the same network until
    everything is transferred over, at which point the old server would be shut

    My only concern is NETBIOS name. The old AD is named, while
    the new AD will be named ourdomain.local, so I don't think that will be an
    issue. But the NETBIOS domain name is OURDOMAIN for both.

    Is it a problem to have 2 ADs on the same network with the same NETBIOS
    domain name? Don't want to plug it in if it will muck things up.

  2. yes, it will muck things up. No, you can't do that. Copy what you need to
    copy to an external USB drive, or a workstation with a big hard disk, or
    whatever. But don't try to have both of them on the same network. Please.
