Let me guess a bit (because I've had the same issue myself): You're on an NT
workstation, with an NTFS filesystem, in an NT domain, and you as an NT user
are local administrator of your workstation? Furthermore you have set
"CYGWIN=ntsec"?
If that's the case be sure your /etc/passwd and /etc/group files are set up
properly, that is by:
mkpasswd -d > /etc/passwd
mkgroup -d > /etc/group
(as is indicated in the User Guide at
http://cygwin.com/cygwin-ug-net/ntsec.html). Then quit cygwin and restart
it. This should have two effects:
1) you will no more get Administrator in your prompt, but your NT user name
2) you will be able to access your files correctly
Oh, but wait a minute; if I understand correctly what you've said, you
should be using a samba share between your Linux box and your Windows
system, with a windows mount of th esamba share as drive E:?
Then the problem may also be (in addition to the above) that your samba
server is not correctly configured to match your NT user name with your
Linux login. Then it may be samba that refuse the access (although in this
case you should not be able to create new files on the share also).
Please could you be more explicit on the exact setting of your system, as
here there is several piece of software that are interacting and any one can
be the cause of the problem.
