need to change Domain controller - old system going bad - need advice

    testing scenario in my home domain I have domain name as DOMAIN before
    trying this at work
    Domain Controller is named Harper.domain
    2nd server is named dataserver2.domain

    on dataserver2 I run dcpromo - start the process but when i get to entering
    domain name it will not allow me to use DOMAIN as it already exists so I
    have to name it HOME.

    at work dataserver1 is running WIn2000 adv server as stand alone Domain
    Controller - the only thing it's running is TrendMicro network anti-virus
    server
    dataserver2 is Win 2003 Enterprise Server running Terminal Server Services -
    Terminal Server licensing Server - Print Server - File Server - Web Server

    this gets scary when thinking about doing this at work since all the active
    directory users and Terminal Server Licenses are in DOMAIN domain and if I
    make dataserver2 at work a domain controller I have to use a new domain
    name, then all our users and Terminal Server Licenses would be lost for new
    domain????

    I have found some tools such as Active Directory Migration Tool and Domain
    renamer that can be used.

    This is not as simple as I thought - my plan was to disconnect Dataserver1 -
    run DCPROMO on dataserver2 and make it the domain controller - did not
    realize the problems involved.

    the other solution I have found is to leave dataserver1 running - run DC
    promo on dataserver2 giving it a new domain name.
    after that process finishes - allow time for replication to occur - then on
    dataserver1 run the Active Directory Migration Tool - check that it worked -
    then demote dataserver1 - if what I read is correct on next reboot
    dataserver2 will popup message it is converting to Primary domain
    controller - then run the domain renamer tool to put the domain name back to
    DOMAIN so all workstations logons and accounts will not be affected.

    Does this make sense?

    If you want to keep the same domain w/o migrating anything.

    Run dcpromo and tell the wizard that the new DC is in the same domain. It
    should be that simple. Once done wait a day for replication and if you want
    to remove the old dc demote the old machine by again doing a dcpromo. Make
    sure that before you demote you have enabled the Global Catalog on the new
    server. Also make sure any dc services on the old dc have been moved
    elsewhere.

    I am looking at your web site for setting Global Catalog but it does not
    appear in my AD Sites and Services

    I highlight Dataserver2 - then how do I get to the option to set global?

    many thanks to both of you for helping me with this. I have my child DC
    setup and all users replicated fine - I have turned off the PDC downstairs -
    this is at my home test lab - I have to be certain I understand everything
    before doing this at the office
