Hallo Vince,

I did that already:
Everyone:*:0:0:,S-1-1-0::
SYSTEM:*:18:18:,S-1-5-18::
root:*:544:544:,S-1-5-32-544::
admin:unused_by_nt/2000/xp:500:544:U-M111\Administrator,S-1-5-21-1801674531-1606980848-1708537768-500:/home/Administrator:/bin/bash
Guest:unused_by_nt/2000/xp:501:513:U-M111\Guest,S-1-5-21-1801674531-1606980848-1708537768-501:/home/Guest:/bin/bash
IUSR_M111:unused_by_nt/2000/xp:1003:513:Internet Guest Account,U-M111\IUSR_M111,S-1-5-21-1801674531-1606980848-1708537768-1003:/home/IUSR_M111:/bin/bash

But changeing the primary group in /etc/passwd won't do anything under
windows. The problem is that files created under windows have the
group None... Windows won't care for /etc/passwd and I didn't find a
way of setting "primary" groups under w2k.

I installed W2k and all its programs as member of the Administrators
group. Will Windows have set its own permissions propperly enough so
that changing ownership from None to root (group Administrators)
shouldn't be a problem? (where None is a user or group) I mean if I
leave IUSR_M111 (don't really know why IUSR_M111 is group Users when
he has access to SSH2 files...) and SYSTEM as it is.

So far nothing should happen, because of the file permissions
?rwxrwxrwx.
If I then change all permissions to 770 - will that work? Permitting
execution to all files is dumb, but saver.

However, newly creates files /installed programs will still have group
None.... :(

Are there good papers on windows (/Cygwin) file permissions?

Ciao
