Migrate users from one DC to another on the same domain

Discussion in 'Active Directory' started by Phil Buzzette, Sep 29, 2006.

  1. I have 2 domain controllers on the domain. The primary and the secondary. I
    want transfer the users, etc. from the primary to the secondary and make the
    secondary the new primary. How can I go about this? When I added the
    secondary as another domain controller, I thought it would do this, but
    whenever I open up AD, I can see that it is reading the account information
    from the current primary.

    All you are seeing is that you are attached to the DC. AD is a multimaster
    database, that replicates its data to ALL dc's. What you are seeing has
    nothing to do with how data is distributed between dc's.

    To attach to another dc while in Active Directory Users and Computers, right
    click and select "Connect to Domain Controller" and key in the dc you would
    like to attach to.

    AD uses multi-master replication meaning there is no primary or secondary..
    Are you referring to Winnt 4.0 ?

  4. I get an error message that says the domain controller can not be contacted.

    The RPC server is unavailable.

    Sounds like it is having problems promoting itself to a dc. Are there any
    messages in the Event logs stating NTFRS or NTDS replication isn't working?

    Run diagnostics against your Active Directory domain.

    If you don't have the tools installed, install them from your server install

    Run dcdiag, netdiag and repadmin in verbose mode.
    -> dcdiag /e /c /v /s:DC_Name /f:c:\dcdiag.log
    -> netdiag.exe /v > c:\netdiag.log
    -> repadmin.exe /showrepl dc* /verbose /all /intersite > c:\repl.txt

    If you download a gui script I wrote it should be simple to set and run
    (DCDiag and NetDiag). It also has the option to run individual tests
    without having to learn all the switch options. The details will be output
    in notepad text files that pop up automagically.

    The script is located in the download section on my website at

    Just select both dcdiag and netdiag make sure verbose is set. (Leave the
    default settings for dcdiag as set when selected)

    When complete search for fail, error and warning messages.

    Are you suggesting that AD is not multimaster, really the only way you could
    say you have a primary is by the location of the fsmo roles or the GC.
