Author Deny Account FTP Access

W2003 Web Edition / IIS6 / Default FTP site / Guest account disabled

I have had to add another user account to the server to secure access for
certain web pages. The new user is not a member of any group and only has
read pemissions on a single directory well under the ftproot.

Suprisingly, although the new user has no effective permissions at the
ftproot level, they are still able to login and browse the full FTP
directory stucture using their username and password. Anonyomous access is
turned off. I can explicitly deny the new user access to the FTP root which
then prevents FTP logon, but surely this isn't the correct way to do this?
With no permissions at the ftproot level users shouldn't be able to logon.

Which account privileges are they assuming when they logon?

ACL for the FTP root has the following entries (it is the Web Root folder)

Administrators
ASP.NET machine account
IIS_WPG
INTERACTIVE
Internet Guest Account
NETWORK
NETWORK SERVICE
OWS_xxxxxxxxxx_admin
SYSTEM
u3822xxxx

The user who I wish to prevent from FTPing is not in the above list and is
not a member of any groups. Allow Anonymous FTP is not checked.

sorry, been very busy...

Mm... interesting.
Restart FTP service and try again. same?

if yes, then somehow and somewhere the user has access permissions. I can't
reproduce your claim. Can you pls verify again...... try a new user that
don't have permission on the path, can the new user able to login as well?
