SYSTEMS AFFECTED

  Win NT
  

PROBLEM


    A unique  machine SID  is created  when machine  is installed  and
    never changes.  User SID's  are extended  versions of  the machine
    SID.  Generally, an SID  from one workstation never finds  its way
    onto another, but this can  happen in rare cases and  could result
    in one user getting another's access permissions.

    To verify this, check out MS Knowledge Base article: Q162001.



EXPLOIT

  

SOLUTION


    This is possible  to occur in  very rare cases,  but no valid  fix
    for now.
