    Dear All,

    I installed new child DC and want to move some users to new child DC by
    using ADMT. However I cannot see my new child DC in source and target domain
    in ADMT. Can I know is there any method to make it appear?

    ADMT uses NetBIOS to resolve the names. Also a two-way trust must be
    established prior to running ADMT.

    Instead of the website you're using, I suggest to use OEx (Outlook Express

    Newsgroups. It is FREE and requires NO ISP's Usenet account. OEx allows you
    to easily find, track threads, cross-post, sort by date, poster's name,
    watched threads or subject.

    I can see the trust relationship is created by default. will it problem
    related to DNS or something else?

    Actually since it is only using the single name in ADMT, it is relying on
    NetBIOS, not DNS, as I previously mentioned. There must be a two way trust.
    Go into the trust on both sides and Verify it. IF there are any firewalls in
    between, that may cause problems too. If on multiple subnets, you'll need

    Otherwise, if still having problems, you can always dissolved the trust and
    recreate it.

    It seems that I can remote the trust in Active directory Domain and Trust
    because it is dim.
    Another concern is that the account I would like to move is from HK to UK.
    So, will the router need to open any port in order to make it appear in ADMT?

    I'm not sure what HK and UK is. Are they domain names?

    If you are trying to do this across a router, you'll need WINS to resolve
    the names.

    I now realize after re-reading your original post that you are doing a intra
    migration (within an org or forest), and not inter migration (between orgs).
    SO the trust is already in place, and that trust is based on Kerberos and
    DNS. For ADMT, the current trust will work fine, but the BIG factor is that
    ADMT must have NetBIOS resolution support, and WINS is the answer here.

    that mean I need to setup wins in source and target domain?
    Can I know what is the step to make new child DC appear in ADMT?

    Setup one WINS server. COnfigure ALL machines to use this one WINS server.
    Very easy to setup WINS. It is a common tool used by numerous organizations.
    It is a NetBIOS database of NetBIOS names (not DNS names). ADMT requires the
    ability to resolve NetBIOS names, and that is what WINS will give it.

    Even install the WINS, still cannot see,
    However, I manually enter the domain name in target domain, it promts the
    target domain is not native mode, whether it is a must to set target computer
    to be native mode?

    For ADMT to work, yes the target domain MUST be in minimum 2000 native mode.

    I can use ADMT to move user from different site with mixed mode in testing

    The "Source" domain functional level doesn't matter. The "Target" domain
    MUST be at least 2000 native.
