    we have an external trust between two AD (2003 (Dom1) and 2008 (Dom2)).

    Our users from Dom1 are able to connect from a computer member of Dom2
    only with the UPN format .

    If they select the Dom from the drop down list in the logon windows, it
    doesnt work . (and if I remember well, the drop down list use the
    Pre-Windows 2000 format "Dom1\username")

    Do you have any idea on how be able to logon to the domain by selecting
    the domain in the drop down list ?

    Thank you

  2. Hello Eric,

    See here about the different options:

    In Vista/server 2008 that way of logon is not longer available.

    Note The logon interface is different in Windows Vista. Therefore, this combination
    will not be available in future Windows releases.

    Best regards

  3. Is there NetBIOS support between both forests, such as WINS replication
    partnership? The drop down box are the NetBIOS domain names, and requires
    NetBIOS support.

    However, as Meinolf mentioned, moving forward, this feature will be phased
