    Change of Forest Functional Level may cause problem with trust?

    Hi at all,
    I would to know if is there some critical issues with pre-existent external
    Trust when you change Active Directory Forest Funtional Level (from Windows
    2000 to Windows 2003 Native Mode)?

    The doubt is in general if it is necessary to recreate the external Trusts
    or no impact is expected.

    Thanks!

    Hi Maurizio

    No issues with the different levels. The Levels only affect the way the
    forest/domains within function and has no impact of external trusts

    Maurizio,
    once you switch to the Windows Server 2003 forest functional level, you
    might be able to take advantage of the forest trust relationship - which
    gives you benefits of transitivity and Kerberos authentication (providing
    that the "other" forest is also operating on Windows Server 2003 - or
    higher - forest functional level)
    Note that this is not a requirement - but simply an additional option you
    have...

    Hello Maurizio,

    Does have no impact on the existing trust. Just as Marcin said check out
    the new options you have. The link includse an overview from all levels up
    to 2008 R2:

    You can break a trust if one of the trusts is to an older NT domain.
    Windows 2003 enforces a stricter security policy.

    If this trust is with an NT domain I have an article on how to configure it
    at:
    http://www.pbbergs.com/windows/articles.htm

    Select NT4 -v- Active Directory Trust
