Check the User Guide:
http://cygwin.com/cygwin-ug-net/ntsec.html
Specially the part about not wanting to be 'None':
Unfortunately, workstations and servers outside of domains are not able
to set primary groups! In these cases, where there is no correlation of
users to primary groups, NT returns 513 (None) as primary group,
regardless of the membership to existing local groups.
when using mkpasswd -l -g on such systems, you have to change the
primary group by hand if `None' as primary group is not what you want
(and I'm sure, it's not what you want!)
Solution:
edit your /etc/passwd and change your primary group to 544
(Administrators)
