I can't reproduce this on 1.7.9 using a domain user following the steps you
outlined above.  Perhaps there's something hidden in your cygcheck output
and passwd and group files that would help?  The only thing that occurred
to me is that my user is part of the local administrators group.  I'm not
sure yours is.  You might investigate that.  Or try with a local user (with
and without admin privs).  Alternatively, if you only care about Windows
permissions and not POSIX ones that Cygwin prefers, you can use the "noacl"
to tell Cygwin to not use POSIX permissions on any part of the file-system.
See <http://cygwin.com/cygwin-ug-net/using.html#mount-table> for more
details.  I recommend this option only as a last resort of course.
