  2. Hello Sam,


    !!!NEVER START BEFORE HAVING CREATED A BACKUP OF YOU DATA/MACHINE!!!

    One question first:
    Is one of the old servers also Exchange server and will it be taken out of
    the domain
    forever, when the new server is running?

    - On the old server open DNS management console and check that you are running
    Active directory integrated zone (easier for replication, if you have more
    then one DNS server)

    - run replmon, dcdiag and netdiag on the old machine to check for errors,
    if you have some post the complete output from the command here or solve
    them first

    - run adprep /forestprep and adprep /domainprep from the 2003 installation
    disk against the 2000 server, with an account that is member of the Schema
    admins, to upgrade the schema to the new version

    - Install the new machine as a member server in your existing domain

    - configure a fixed ip and set the preferred DNS server to the old DNS server
    only

    - run dcpromo and follow the wizard to add the 2003 server to an existing
    domain

    - if you are prompted for DNS configuration choose Yes (also possible that
    no DNS preparation occur), then install DNS after the reboot

    - for DNS give the server time for replication, at least 15 minutes. Because
    you use Active directory integrated zones it will automatically replicate
    the zones to the new server. Open DNS management console to check that they
    appear

    - if the new machine is domain controller and DNS server run again replmon,
    dcdiag and netdiag on both domain controllers

    - if you have no errors, make the new server Global catalog server, open
    Active directory Sites and Services and then double-click sitename, double-click
    Servers, click your domain controller, right-click NTDS Settings, and then
    click Properties, on the General tab, click to select the Global catalog
    check box (http://support.microsoft.com/?id=313994)

    - Transfer, NOT seize the 5 FSMO roles to the new Domain controller (http://support.microsoft.com/kb/324801)

    - you can see in the event viewer (Directory service) that the roles are
    transferred, also give it some time

    - reconfigure the DNS configuration on your NIC of the 2003 server, preferred
    DNS itself, secondary the old one

    - if you use DHCP do not forget to reconfigure the scope settings to point
    to the new installed DNS server

    - export and import of DHCP database (if needed) http://support.microsoft.com/kb/325473


    Demoting if needed

    - reconfigure your clients/servers that they not longer point to the old
    DC/DNS server on the NIC

    - to be sure that everything runs fine, disconnect the old DC from the network
    and check with clients and servers the connectivity, logon and also with
    one client a restart to see that everything is ok

    - then run dcpromo to demote the old DC, if it works fine the machine will
    move from the DC's OU to the computers container, where you can delete it
    by hand. Can be that you got an error during demoting at the beginning, then
    uncheck the Global catalog on that DC and try again

    - check the DNS management console, that all entries from the machine are
    disappeared or delete them by hand if the machine is off the network for ever



    Best regards

  4. Change that to:

    Never start before having created AND TESTED a backup of your data/machine

    Hi Meinolf,

    I am ruining C:\I386>adprep /forestPre on a member server windows 2003 .
    Trouble is that adprep/forestprep says that:
    Adprep cannot run on this platform because it is not a domain controller
    [Status/Consequence]
    Adprep stopped without making any changes.
    [User Action]
    Run Adprep on a domain controller.

    Thanks,

    Sam

  7. Hello Sam,

    You have ti run adprep on the schema master of the domain with an account
    that is member of the schema admins, not on a member server. To find out
    your schema master run on a DC "netdom query fsmo" without the quotes on
    a command prompt.

    Best regards
