chmod, ownership, etc

[timcygwin <tim at thedorsetpagdens dot plus dot com>]

I have the following cygwin environment set up:

/etc/passwd hacked such that user tim has group 544 rather than 513
  tim:unused_by_nt/2000/xp:1002:544:tim
othy,U-olorin\tim,S-1-5-21-**etc**-1002:/home/tim:/bin/bash

cygwin installed on a shared Windows directory (E:\utils\cygwin\), with the
key Windows volumes made visible using links:
  ln -s /cygdrive/c /C
  ln -s /cygdrive/d /D
  ln -s /cygdrive/e /E
  ln -s /cygdrive/f /F
  ln -s /cygdrive/p /P
  ln -s /cygdrive/i /I
  ln -s /cygdrive/l /L
  ln -s /cygdrive/t /T

/home/tim 'remapped' to my Windows area
  rm -rf /home/tim
  ln -s /F/users/tim /home/tim

and to enable chmod'ing to work:
  export CYGWIN=smbntsec

Problem is that the existing files in my Windows area have user ownership
Administrators, group ownership None, e.g.,
  -rwxrwxrwx  1 Administrators None            5513 Jul 20  2005
set_from_reg.awk*

whereas new files created under cygwin have owner tim, group Administrators
  -rw-r--r--  1 tim            Administrators     0 Jan 25 08:51 rti

Before I run through a recursive chown & chgrp to have the ownership set as
desired (tim/Administrators not Administrators/None), is there something
that I need to do to fix the ownership rights to save having to recursively
set them. And will recursive chown & chgrp screw up the existing Windows
ownership?

Well I've had a quick play, creating files under Windows come up with
ownership Administrators/None, files created under cygwin come up with
ownership tim/Administrators, so I'd really like to have cygwin set up such
that it reports tim/Administrators rather than Administrators/None even for
files created under Windows - or perhaps the solution will be: What you need
to set up in Windows such that ownership  will be reported as
tim/Administrators.

Hope you can help...
