Hi,

You may have misread the original question (and its subject): the POSIX 
permissions are 070, not (0)700.  These files are accessible to one or 
more of the groups the owner is a member of, but not to the owner.

+1 for the ICACLS workaround though.  I was bit by this recently when 
setting up openssh, which cares about locking down access to keys.  I 
needed to get rid of those group access bits, but chmod left them 
unchanged.   I used ICACLS to remove ACEs for 'NT AUTHORITY\SYSTEM', 
which (based on experimenting) were affecting the 'group' triplet of the 
POSIX permissions.

Cheers,
Tim
