Where do you get this message and how?  Can you a bit explain how you test
it and send the matching strace snippet?

Are you running the services as SYSTEM or as another user account?  In
the latter case, you must add the SeTcpPrivilege to that account.
Otherwise I have no idea what's wrong for you.  I have five systems with
four different OSes (2K, XP, 2K3, 2K3 R2 x64) running with
subauthentication and I only had problems on 2K3 with two facts, the
first being that the account was missing the SeTcbPrivilege, the second
being that the subauth DLL must be built as 64 bit DLL to run correctly
on 64 bit Windows.
