    You're mixing two concepts here - the "defaultNamingContext" is a
    property of the GC / LDAP world - you won't have access to that
    through WinNT. There is no "defaultNamingContext" in WinNT.

    The WinNT world is flat - you have a server, with a bunch of users and
    groups - that's it - no hierarchy, no naming contexts, nothing like
    that. If you want to search, you'll probably just have to bind to
    "WinNT://<local machine name>" as the base path, and then specify what
    you want to search for. Not quite sure how you have to set up the
    filter - usually, that's an LDAP filter which has to be conformant to
    the LDAP search syntax (something like


    But again - since you're not using the LDAP provider, this probably
    won't work....
